Peptides, explained simply

A peptide is a small chain of amino acids — the same building blocks that make proteins, just shorter (usually 2–50). Their job is mostly communication: peptides act as messengers that tell cells to do something, by binding to specific receptors like a key in a lock.

We organise peptides by their primary research focus — body composition, healing & recovery, cognitive, anti-aging, immune, skin & hair, and more. A peptide can touch several systems, but its category reflects what it's most studied for. Browse by category to find what's relevant to your research interest.

Every profile states a research status. A few peptides are FDA-approved medicines (e.g. tesamorelin, bremelanotide). Many more are in clinical trials, and most are preclinical — studied only in cells or animals. We label this precisely because conflating these stages is the most common source of misinformation. Preclinical evidence does not establish human safety or efficacy.

With research compounds, what's on the label has to match what's in the vial. That's why third-party testing, HPLC purity verification, and a batch-specific Certificate of Analysis (COA) are the markers that separate credible suppliers from the rest. When you evaluate any product, look for those first.
