Everything a new researcher needs to know: how to source verified peptides, reconstitute correctly, store for maximum stability, and administer safely. A complete four-step onboarding guide.
Source from a verified supplier
The most important decision you will make is where you buy your peptides. The research peptide market has no FDA oversight, which means product quality varies enormously — from pharmaceutical-grade compounds with third-party COAs to mislabeled or contaminated products.
Reconstitute correctly
Research peptides are shipped as lyophilized (freeze-dried) powder. Before use, they must be reconstituted — dissolved in a liquid solvent — to create an injectable solution. Bacteriostatic water (BAC water) is the standard reconstitution solvent.
Store properly
Lyophilized peptides: store at -20°C for long-term (up to 2 years), or 4°C for up to 3 months. Reconstituted peptides in solution: store at 4°C and use within 30 days. Avoid freeze-thaw cycling of reconstituted solutions.
