Peptides 101
What peptides are, what they aren’t, and how to read everything else on this site.
What is a peptide?
A peptide is a short chain of amino acids — the same building blocks that make up proteins, just fewer of them. Your body already makes thousands of them. Insulin is a peptide. So is the GLP-1 your gut releases after a meal.
The peptides on this site are mostly copies or tweaks of signals the body already uses. That is the appeal: rather than introducing something foreign, they turn up (or down) a process that already exists — appetite, repair, growth hormone release.
What they aren’t
- Not magic. They nudge biology. Sleep, food and training still do most of the work.
- Not all approved. A few are FDA-approved medicines; most are not. Every page says which.
- Not all equally studied. Some have large human trials; others are mostly animal research and real-world experience. Every page tells you where the evidence stands.
How to read a peptide page
Each peptide has a dossier. The panel on the left is the quick reference: what it is best known for, how often it is taken, how long a typical run lasts, and its approval status. The numbered sections on the right go deeper — how it works, who uses it, the shape of a typical run, what to watch for, and the evidence.
The run profile shows the shape of a typical build-up — start low, step up in phases. For the exact amounts for your vial and your situation, use Ask.
Three habits worth having
- Start low, go slow. Almost every protocol begins below the target and climbs. Tolerance first, results second.
- Change one thing at a time. If you start two compounds on the same day, you will not know which one is doing what.
- Keep a log. Dose, day, how you felt. It makes every later decision easier.
