FAQ

PrymaLab is an American-made peptide research supply company. We specialize in providing the purest research peptides, lyophilized peptide compounds, and liquid research chemicals to scientists, laboratories, and qualified researchers worldwide. Every product in our catalog is manufactured in the USA and guaranteed to meet 99%+ purity standards verified through HPLC testing and third-party analysis.
Absolutely not. Every product sold on PrymaLab.net is strictly for research purposes 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 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 will ship the following business day (excluding Sundays). Because all of our research peptides ship from within the United States, delivery times are exceptionally fast regardless of your chosen payment method.
We do not process orders by phone. We utilize a professional answering service that will forward your inquiry to our support team, but all research peptide orders must be placed directly through our website at PrymaLab.net to ensure accuracy and security.
Our reputation depends on delivering the purest research peptides available. Every product is tested using HPLC analysis and mass spectrometry to verify molecular identity and purity. We guarantee 99%+ purity on all research peptides — if any product fails to meet this standard, we replace it free of charge. Certificates of analysis are 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.

No. All liquid research chemicals are stable at room temperature. However, we recommend refrigerating any 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 are shipped and stored. Lyophilized peptides remain stable at room temperature for approximately two years and do not require refrigeration until reconstituted. This method preserves molecular integrity, purity, and potency throughout storage and transit.
