KNOWLEDGE BASE

FAQ

PrymaLab is an American-made research peptide supply company. We specialize in the purest research peptides, lyophilized peptide compounds, polypeptides, and liquid research chemicals for scientists, laboratories, and research professionals nationwide. Every product in our peptide catalog is manufactured in the USA, guaranteed to meet 99%+ purity verified through HPLC testing and third-party analysis, and supplied for research use only.
Absolutely not. Every product sold on PrymaLab.net is strictly for research use only and is not intended for human consumption under any circumstances. If any product is intentionally or accidentally ingested, contact a healthcare provider immediately. Any customer who indicates intent to consume our research peptides will have their order canceled and their account permanently suspended. PrymaLab will not discuss the potential effects of ingestion — doing so would be unlawful.
Most orders are processed and shipped the same day they are placed. Orders submitted after 12:00 PM EST ship the following business day (excluding Sundays). Because our research peptides ship from within the United States, nationwide shipping is exceptionally fast regardless of the payment method, such as credit cards, you choose.
We do not process orders by phone. Our professional answering service forwards inquiries to our support team, but all research peptide orders must be placed directly through PrymaLab.net to ensure accuracy and security.
Our reputation depends on delivering the purest research peptides available. Every product is tested with HPLC analysis and mass spectrometry to verify molecular identity and purity. We guarantee 99%+ verified purity on all research peptides — if any product fails to meet this standard, we replace it free of charge. A certificate of analysis is available with your order for complete transparency.
All of our research peptides and liquid research chemicals are proudly manufactured in the United States. PrymaLab is committed to American-made quality, ensuring every product meets the highest standards of purity, potency, and scientific integrity.
A certificate of analysis (COA) is a document that reports the laboratory test results for a specific peptide batch. Each PrymaLab COA confirms molecular identity, 99%+ verified purity, and potency using HPLC and mass spectrometry. A COA is available with every order, so you can confirm exactly what your vial contains before research begins.
If your order did not process, try clearing your browser's cache or switching to a different browser. When you successfully click "Process Order," a processing status bar appears and typically completes within 30 seconds. If it takes longer than 2 minutes, contact our support team. Check your inbox and spam/junk folders for the automatic confirmation email, which is sent immediately upon successful completion. Our live chat is available 9 AM–9 PM EST for real-time help.
Contact our support team as soon as possible and we will update your shipping information. If your order has already shipped with incorrect details, you will need to wait until the package is returned to our facility before we can reship it. We cover reshipping fees for domestic orders within the USA; international reship fees are the customer's responsibility.

No. All liquid research chemicals are stable at room temperature. We do, however, recommend refrigerating research peptides after reconstitution with bacteriostatic water to preserve stability.
Lyophilized is the scientific term for freeze-dried. It describes the state in which our research peptides ship and are stored. Lyophilized peptides remain stable at room temperature for approximately two years and don't require refrigeration until reconstituted. Freeze-drying preserves molecular integrity, purity, and potency throughout storage and transit.

ok i was honestly skeptical because ive tried SO many hair supplements and most of them do nothing. But the HHB blend is different, within a few weeks of my research protocol i started noticing less breakage and my nails stopped peeling at the tips. The janoshik COA gives me confidence im working with a legit product. Price is way better then the competition and i love that its american made. Already set up my monthly subscription

What really sets this company apart is the pricing, i compared it to 4 other sites and prymalab is cheaper accross the board. Will be a regular customer

This blend is priced better then buying the two compounds seperately from most other sites, which is wild. Packaging was solid, came with the janoshik report and everything looked great. I've tried 3 other suppliers for this same blend and prymalab is the best combination of price, quality and shipping speed. Veteran owned too which is always a plus in my book

This is my second order of the HHB blend and i have no plans to stop. The quality is consistent, which matters alot for serious research protocols. Both batches had janoshik COA's and both tested clean. I set up the monthly subscription after my first order and the savings are significant. Prymalab is genuinely the best supplier i've used in terms of price AND quality combined, usually you have to sacrafice one for the other

Really impressed with the quality here. The nasal spray format is so much more convenient for my research protocols and the concentration is exactly what the label says per the lab report.
