We verify every batch of every product with the help of accredited independent third-party laboratories. The equipment and methods required for each product vary widely. For this reason, we work with several specialty labs and PhDs in analytical and organic chemistry to design our analytical methods Analytical techniques we use include NMR, FTIR, HPLC, LC-MS, GC-MS, TLC, ICP-MS, Gravimetry, UV-Vis, Titration, Melting Point, Organoleptic. You can read more about our QC process on our Quality Control page.

A certificate of analysis, like any other certificate, is as valuable as the issuer and the trust you place in the issuer. A COA from a company that you do not have a relationship with and which does not have a track record of ethical behavior is unreliable. In the absence of trust, you can rely on raw analytical data and for that reason we generally try to provide this raw data or use well known contract labs for our third-party analysis. In the absence of trust and data you should not trust a certificate of analysis. A reputable company or lab should be able to provide raw analytical data. This comes up frequently in wholesale trade where a middle-man trading company provides a COA they made themselves in a PDF editor. Since the certificate is counterfeit they cannot provide raw data. They cannot tie it to a reputable third-party lab. They cannot answer technical questions. If pressed they may deepen the lie and steal a spectra or chromatogram from the internet and present it as their own. How do you know the spectra or chromatogram is not real? It is usually obvious, look at the dates, the file names involved, the sample name, run a google image search, or ask someone with the expertise to read analytical data.

Third party testing helps assure you are getting exactly what you paid for. A vendor can tell you whatever they want but if an independent third-party registered lab is certifying it, what they say will carry more weight. Let’s go into detail about what that means. A third-party lab is a lab that is not run by the vendor or the manufacturer (first and second parties). The third-party lab should also be independent, meaning they are not controlled by the other parties and have no conflict of interest about the results of analysis. It’s important the lab is reputable. If the lab doesn’t know what they’re doing or cuts corners it means their analysis might not be valid. There is a lot of fraud in the analytical chemistry industry, and it’s important to work with companies that value integrity and ethics. We’ve seen unethical labs ask their clients what they want the results to say, before they even get a sample in. We work hard to assure our contract labs are both ethical and use well validated analytical methods.

Generally, our single molecule product purity standard is ≥98% by HPLC and many times our products test ≥99%. Some products are standardized to a specific purity, such as Alpha GPC 50% or botanical extracts that have a more nuanced definition and involve multiple active components.

Yes, we verify every batch of every product. You can view independent third-party lab analysis on “OUR CERTIFICATES” Regardless of what vendor you use, you should always request evidence of independent testing. Anything coming from a manufacturer or Chinese trading company is a no-go. Look for accredited domestic laboratories that have tied their name to the lab report and who would be liable if the report was false.

There may not be a noticeable difference between ≥99% and ≥95% pure products. However, the problem is that you don’t know what’s in the impurity. It is usually residual reagents, byproducts or side products. In some cases, these impurities can be toxic. And to a degree, impurities cannot be fully eliminated. It is difficult to characterize every byproduct and side product of synthesis and some impurities are just too small to measure. But impurities can be minimized. For that reason, the standard chromatographic purity in the pharmaceutical and nutraceutical industries is ≥99%. Whenever possible we carry ≥99% products. If this is not possible at production scale we carry the next best option (e.g. ≥98%, ≥95%) and make this publicly known on our COAs. Where appropriate we test for specific toxic residuals, byproducts and heavy metals.

The answer is yes… and no. Where possible we provide easy to verify spectra e.g. NMR, FTIR. Where this is not possible because the third-party lab considers the data proprietary we do not. As you know, we publicly post lab reports, certificates of analysis, from independent third-party laboratories, the same reports which we use to approve and validate our materials and production processes. These reports are publicly available to you, dear reader. However, a certificate of analysis is not raw analytical data. And a certificate may not be worth much if it’s not tied to any certified, trusted body. To use a metaphor: an SSL browser certificate is required for your browser to trust HTTPS protocol pages. An SSL certificate from you or me with no reputation for browser security isn’t going to be as trustworthy as an SSL from Verisign which has a long-standing reputation for protecting its encrypted keys. That is such a consensus belief that your browser will just ignore SSL certificates from unknown entities and label the webpage as untrustworthy. Our certificates of analysis, our lab reports, are from trusted third party independent, registered laboratories. They are accredited for or compliant with relevant ISO standards. They are not something a fly-by-night trading company made at a moment’s notice. They are tied to unique lab IDs from an entity you can contact to verify, who is based in the EU and whose business depends on the validity of their statements, just like “Skylab”. Additionally, they include unique product batch and lot IDs that are printed on each product we carry – so you can look up the corresponding lab report for each product. All of this is tracked throughout our production process in a chain of custody with batch data going back years. You may want to check the quality of the product at: www.skylab.clinic , just by entering the unique codes on the website exact area for this need. But, you ask, why don’t you include the raw analytical data, analytical methods, spectra and chromatograms in your lab reports? Well, you probably already know this. Analytical chemistry is a big business. Accredited, validated methods can cost upwards of 20,000€ to produce. Most analytical labs are adapting methods from the scientific literature, which is a fast way to develop something that works. Exactly what methods they use are proprietary, they don’t want a competitor to know how they verified a specific material. So, they are unlikely to share this, or at least all of it. But, you ask, the lab could share the spectra and chromatograms? Yes, and typically we do request FTIR, LC-MS, and NMR spectra. In the case of HPLC chromatograms, they will be meaningless without additional information, such as the equipment used, blank runs for comparison, and analytical methods. In the past we have paid an additional fee to have HPLC chromatograms included in lab reports. But inevitably the lab will censor or omit details to protect itself. If you feel very strongly about this you can contact us and we can request chromatograms for specific reports at our expense. But, you ask, aren’t you just trusting the lab, why should I trust your analytical lab? Yes, that’s true. We trust, but verify. Besides doing due diligence on potential analytical partners, we interview their staff and cross-examine the lab reports they send us. In some cases, the reports are easy to verify, such as an NMR or FTIR spectra. With HPLC chromatograms that is not the case. We can send samples to other laboratories and confirm the result. And that is what we’ve done numerous times for each of our partner analytical labs. We have sent samples to trusted secondary labs to confirm their results and if there is a discrepancy then we know something untoward was happening and we won’t use that lab anymore. That is broadly our process for validating analytical partners. All publicly posted lab reports on our product listings come from these trusted laboratories that we have consistently cross-examined and verified successfully. So, beyond their long-standing reputation, this is why we trust the results we receive from partner laboratories. I hope that lends some insight into our analytical process and why chromatograms are not generally included in our lab reports. The data is not useful without additional information which, as a standard of industry, is unlikely to be divulged.

If we decide to carry a product we use our contacts and industry resources to search for suppliers. Once we compile a list we begin the vetting process. From the most reputable we request samples. If the samples pass verification we request additional samples. If the samples are consistent we make a larger order. Once we receive a raw material we quarantine it and evaluate it organoleptically. If it appears free of adulteration and contamination we send a sample to an accredited independent third-party lab for analysis. Our analytical methods are derived from the scientific literature where possible or else developed by PhDs in analytical and organic chemistry. If the lab reports match our specifications we OK the product for production. If any of that process fails we start all over.

Our products are made in an ISO:9001 compliant facility. While we’d like to provide more detail on our exact production, manufacturing processes and what equipment we use this is generally proprietary information we cannot share. We do discuss our QC processes publicly however and you can read more about them on our Quality Control page.

With the exception of standalone sterile pipettes our products are not sterile and we cannot make guarantees of sterility. That said we do make efforts to minimize the possibility of microbial contamination through the use of PCO air filtration and micropore filters in our liquid filling machines.

We encourage independent testing of our products. If you wish to verify our products with an independent third-party laboratory we are happy to replace any products used in the testing. Simply furnish us with a copy of the results of the test and give us the order number that it was purchased on and we will replace the tested products for free. We are very confident in the products that we sell and an excellent way of showing this is through independent blind tests done by our customers.

Yes, we do. Please visit the link “For Business” for more info. If you need additional price breaks or unlisted products please contact us and we’ll see what we can do for you.

Our products are not approved for medical use or for the treatment, prevention, diagnosis, or cure of any disease or illness. In addition to being unsuited and unsafe for human consumption, they are not approved for sale to, or possession by, anyone other than someone qualified to handle them in a laboratory setting. We encourage our clients to seek qualified legal counsel in reviewing their potential use of our products, but we cannot provide such counsel ourselves.

Liquid solutions are measured by volume. Volume can be measured by a graduated beaker, graduated pipette, etc. All of our liquid products come with a graduated pipette for measurement.

Liquid solution products are preferred because they have more efficacy absorbed by buccal mucosa and they bypass liver toxicity.

Besides the additional labor, materials and packaging, solutions also require additional quality control procedures. For comparison, to analyze a powder product, you only need a single sample sent out for analysis, even if the batch is 10kg+, provided the batch is uniform and the sample is representative of the whole.To verify a solution product, you must measure both the concentration and the uniformity. This can be done by sampling the mixing vessel before bottling or by sampling individual bottles. We do the former, though in the past we did the latter. Both are acceptable according to cGMP; however, we prefer the former because of the greater certainty it gives us about what goes into each individual bottle. When sampling a mixing vessel, you must take samples at different locations in the vessel and then each must be within the acceptable error bound (±10%) of your expected average concentration. When sampling bottled products, you must sample a sufficient number of them that you have statistical confidence in the sample mean – this usually means about 3 samples per 1000 bottles. The latter is more expensive and less certain. In addition to verifying concentration and uniformity, we also audit our finished inventory and send randomly selected finished products out for analysis.

We provide proper storage instructions on each product listing and on product labels for each product. Generally, store in a cool, dry place away from heat, moisture and sunlight.

The fastest way to determine if we sell a product is to use our website’s search feature which can be accessed from the main navbar menu. Look for the magnifying glass.For FAQ search purposes we will include a list of keywords we do not carry here: nolva, tamox, clomid, climid, clomo, clomifene, pct, post cycle therapy, tamoxifen

Yes, all of our products come with a 14-day money-back satisfaction guarantee. If you are at all unsatisfied with your product within 14 days of delivery (receipt of goods) we will issue a refund or provide a remedy.

You can determine the date of manufacture of your product by reviewing the batch specific ID report which is dated with the product manufacture date at www.skylab.clinic You can then match up the lab report using the “Lot Number” found on your product label. All lab report titles contain a number which will correspond to the lot number on your product label and a date when the lab analysis was conducted. This date can be used as the date of manufacture. All our products though, have on their label’s expiry date and not even a batch of product stays more than 8 months.

Unfortunately, we are unable to accept payments sent via PayPal. This is not by our choice. As a general policy, PayPal has made a willful choice to not work with the majority of bulk chemical vendors. While some smaller vendors in and out of our industry are able to offer PayPal, it is only because they have not triggered PayPal’s internal audit thresholds. We encourage additional questions or feedback regarding this policy to be directed towards PayPal’s customer support team.

Unfortunately, we are unable to accept payments sent via Amazon and Stripe for the same reason we cannot accept payments from PayPal. We encourage additional questions or feedback regarding these policies to be directed towards the respective customer support teams of those companies.

Fortunately, we can accept Western Union or MoneyGram. Please contact us to discuss on this subject.

Yes, we do.

Our checkout prices are denominated in BGN (Bulgarian Lev). Prices may be displayed in your local currency if our multi-currency system is enabled. Any way, you should receive an email indicating the price you paid/pay in € (Euro).

We ship from Bulgaria. Please review our shipping policies for more details about estimated shipping times.

This depends on the courier, service and destination you select. The easiest way to determine shipping cost would be to add products to your cart and go to the checkout page.

We primarily use BG Post Services. We also offer services by GLS. Please visit the following page for more details like estimated arrival time: Shipping & Returns

Yes, we offer free BG Post Services Priority Mail shipping on EU orders over €100 and free GLS Express International shipping on orders over €200.Yes, we do.

Your order should ship within 1-3 business days. If there is an issue we will notify you.

It takes 7-14 days to all points in Europe an order to arrive to its destination. If it takes longer, we are going to take an action, to send a request to the freight forwarder to search for the package and to have an update for its actual state. After 30 days of missing information about the package we are going to consider it lost and we resend it for free.

Unfortunately, no. We offer BG Post Services shipping for EU orders which is the fastest service BG Post provides. For most packages this takes 5 – 10 business days with delivery confirmation and tracking. Estimated arrival time is NOT guaranteed, and is only accurate about 70-80% of the time. While it’s true BG Post has a 30-day refund guarantee. We will not refund if the package is late. We would love to, but BG Post makes it difficult to claim a refund, usually requiring phone calls and a wait of several weeks. GLS has 99% on time delivery without any lost.

X-Stream Force packaging is non-descript and there are no markings that suggest the contents. The shipping label mentions – herbs. We use plain shipping materials including padded envelopes, mailer boxes, zip lock bags, and BG Post flat rate packaging.

We cannot ship products without labeling. The products we sell can be harmful if used improperly and as a matter of regulatory compliance we label them so that proper warnings are visible. We apologize for any inconvenience that this may cause. For international orders we modify labelling in a way that is expedient while remaining compliant with declarations and customs requirements.

Yes, we will send you a tracking number as soon as the order ships within 1-2 business days and provide regular email updates on the tracking status from then on.

You should start receiving tracking updates via email within 1-2 business days of your order being paid. To look up your order tracking, please visit the following page: Track My Order Alternatively, registered users can find their tracking on their order history:

1. Log into your account
2. Go to theOrder History tab
3. View your most recent order
4. Your tracking number will be in the order details

There can be a delay of up to 48 hours in a courier’s online tracking system. A tracking number that is “not found” means the courier does not have the tracking number in its system yet or the tracking system is down, which happens frequently. A tracking status of “info received”, “waiting for shipment”, “accepted”, “no information”, means the shipping label has been paid but the package has not yet been scanned in by the post office. Since couriers can (and do) miss scans a package can have these statuses and still be in transit. In that case you need to allow a few days for the status to be scanned again and update.

If there has been a mistake with the address provided for shipment, or a shipment was unable to be signed for, the Postal Services will generally return the packages to the sender. Once the package has been returned to our shipping facility, we will notify the customer by the next business day. We will offer a reship one time, at our expense, either to the same address or an updated address. Updated tracking information will be provided once the package has been reshipped.

We will not keep your payment if you never receive the goods. If package tracking stops updating for over 15 days domestically or over 30 days internationally, we will review the case for a reship. We will offer at least one free reship. If the second shipment fails we will consider options including changing destination address, changing shipping service and issuing a refund. If the issue is related to international customs we can typically improve the odds of passage by changing the shipping service or courier.

Some orders may require a signature confirmation for delivery, depending on the order value and courier used.

If the tracking says Delivered but you have not received the package there are a few possibilities. It’s possible the package was received by someone else. Couriers can drop off packages at the wrong address, street or mailbox and this is unfortunately common. It is also possible your neighbor, a front desk, receptionist, mailroom, doorman, HOA or colleague received the package. We recommend asking around before concluding the package is missing. If you still can’t find the package you should contact the courier directly, our tracking emails will provide contact information. Couriers will have precise GPS coordinates for every tracking scan and can tell you where the package was scanned when the status was changed to Delivered. Be sure to have your tracking number on hand. Tip: If Postal services delivered your package it will be easier to call or visit your local post office and ask to speak with the Postmaster about your missing delivery. If you suspect the package was lost or stolen please file a claim with the courier and/or a police report. We typically recommend waiting 1-2 weeks for the package to turn up, usually a neighbor or colleague has it. If it never turns up please get in touch with us and provide proof you filed a claim or police report. We will handle this on a case by case basis and may require you to sign a legal affidavit to submit to our insurance company, so we can issue a free reship.

Delivery Exceptions are events that may delay the delivery of a shipment. They can be triggered by a customs issue, the recipient not being available to sign, holiday delays, natural disasters, shipment refusal, invalid addresses, returns to sender, etc. In the event of a delivery exception you will be automatically notified by email via our tracking update system. We will also receive the same email and may contact you about it if further action is required. Most of the time no action is needed on our part. However, for Returns to Sender, Refusals and International orders there is often some further processing.   If the tracking says Delivered but you have not received the package there are a few possibilities.
