Why this site exists

Almost every peptide website is a store with an education tab bolted on. The dosing guide exists to sell vials, the database is a product catalog, and the "reviews" are written by the people selling the product. That makes it hard to find two things people actually need: an honest explanation of what a compound does and where the evidence stands, and a way to tell which vendors will ship what they say they will.

amino101 is a reference first. It does not sell peptides. Each entry says what a compound is, how it is thought to work, what has actually been shown in humans versus animals, what dose ranges show up in research and community use, and what people get wrong. The calculator shows its math. The glossary explains the jargon. The vendor list is short and has rules.

How it is funded

Some vetted vendors provide a promo code or referral link. When you use one, you get a discount and the vendor pays a commission. That is the only revenue. Vendors cannot pay to be listed, ranked, or kept on the list. See how we vet vendors for the checks.

What this site is not

It is not medical advice, and it is not a recommendation to use anything. Most compounds covered here are not approved for human use and are sold as research chemicals. Dose ranges describe what appears in published studies and community protocols so you can understand what you are reading elsewhere, not so you can copy them. Talk to a clinician who knows your history.
