ABOUT US
IMPORTANT NOTICE — PLEASE READ FIRST: All articles and product information provided on this website are for informational and educational purposes only. The products offered on this website are furnished for in-vitro studies only. In-vitro studies (Latin: in glass) are performed outside of the body. These products are not medicines or drugs and have not been approved by the FDA to prevent, treat, or cure any medical condition, ailment, or disease. Bodily introduction of any kind into humans or animals is strictly forbidden by law. PrymaLab sells only to qualified laboratories and verified researchers.
Who we are
PrymaLab is a veteran-owned research peptide supplier in Ashland, Kentucky. We sell lyophilized research peptides, peptide blends, nasal sprays, preloaded auto-injector pens and capsules to laboratories and qualified researchers for in-vitro research. We are not a compounding pharmacy and we do not sell supplements.
Two things describe how we work. First, our peptides are made at synthesis facilities in the United States, and every lot is tested in our own laboratory before it is packed. Second, the results of that testing are public: each lot ships with a numbered certificate you can open, verify and download, and the specification it was tested against is printed on it.
Our own testing is exactly that, our own. It is not independent verification and we do not describe it that way. Where an outside laboratory has tested our material we link the report, and if you have a lot tested yourself and it does not match the label, we refund the order and the cost of the test. The rest of this page explains how the material reaches you and what the paperwork says.
The catalog is organised by research area: healing and recovery peptides, growth hormone and performance peptides, weight loss and metabolic peptides, cognitive, sleep and mood peptides, peptide bioregulators and research chemicals. The research hub holds the background reading for each range, the purity standard page states the specification every lot is tested against, and the research use and compliance page sets out what we will and will not sell, and to whom.
Where the peptides come from
We do not synthesize peptides in Ashland. The compounds in our catalog are made for us by synthesis facilities in the United States. We do not name those suppliers and we do not pass their paperwork on as our own; what we stand behind is what we measure. Each incoming lot is sampled and tested in our laboratory before any of it is labeled or sold under the PrymaLab name, and a lot that misses the specification is not released.
Everything after synthesis that we control happens in Kentucky: testing, labeling, lot numbering, packing and shipping. Nasal sprays and auto-injector pens ship cold chain. Because stock is held in Ashland, orders ship from inside the United States, with no customs step, and in-stock items can leave the same day.
How every lot is tested
Our laboratory, PrymaLab Analytical, runs five tests on every lot:
- Purity by reversed-phase HPLC on a Waters Alliance e2695 with Empower 3 software. The specification is 99.0% or higher, with no single impurity above 1.0%.
- Identity by LC-MS on a Waters Acquity SQD: the observed mass must be within 1.0 Da of the theoretical mass for the sequence.
- Water content by Karl Fischer titration, 5.0% or less.
- Bacterial endotoxin by LAL, 5.0 EU/mg or less.
- Sterility to USP <71>.
The results, the peak table and the chromatogram go on the lot certificate, with the analyst, the reviewer and the laboratory director who signed off. The laboratory is ours, so its reports are not independent of PrymaLab, and it is not accredited to ISO 17025; the certificate is the record of what we measured on the lot you receive, nothing more. The same laboratory tests outside samples through our lab testing service.
Reading a PrymaLab certificate
Every lot has a number in the form PL-2609-010 and a certificate number in the form PL-26-00010. The certificate has two pages. The first carries the lot facts (compound, label claim, dates, units in the lot and units sampled) and the results against each specification; the second carries the HPLC method, the peak table and the chromatogram. Both pages are on the product page and in its gallery, and every published certificate is listed at /testing/results/.
Each certificate also carries a verification key and a QR code. Enter the number and key at /testing/verify/ and the site shows the certificate as it was issued, so a copy cannot be edited and passed off as ours. The lot number is printed on the vial label. Partners who sell our material under their own brand receive the same certificate issued under their name, with the test data unchanged.
To read one, start with the lot number on your vial and match it to the certificate. Then read the purity (the main peak as a percentage of all detected material), the largest impurity, the observed mass against the theoretical mass, and the water, endotoxin and sterility lines. The date of analysis is on page one. Certificates currently state the label claim per vial; a measured peptide content per vial is being added to new certificates.
Guarantee, documentation and who we sell to
Third-party testing guarantee. Have any PrymaLab product tested by an independent laboratory of your choice. If the result does not come back as the compound named on the label, at the purity and amount stated, we refund the order in full and reimburse the cost of the test. Send the lab report and your order number to michael@prymalab.net.
Outside testing we can show. Janoshik Analytical tested our Semax 11 mg (batch 001) in January 2026 and reported 12.09 mg of peptide at 99.39% purity. The report is on the Semax 11 mg page and can be checked on Janoshik’s verification page. It is the only outside report we hold today; others will be added as they are done.
Safety data sheets. We publish a GHS-format safety data sheet for every compound and form we sell, 189 at the time of writing, each with a PDF.
Who we sell to. PrymaLab sells only to laboratories and qualified researchers, and every product is furnished for in-vitro research. Nothing we sell is a drug, a medicine or a dietary supplement; none of it has been evaluated or approved by the FDA to diagnose, treat, cure or prevent any condition; and bodily introduction of any kind into humans or animals is prohibited. We do not publish dosing or protocol information and we do not answer questions that assume a use outside a research setting. The research use and compliance page sets this out in full.
Partners. Research suppliers and stores that sell under their own label buy through the partner program: the same lots, the same certificates issued under the partner’s brand, and label artwork handled in the partner dashboard.
