The peptide database

Graded on who it was tested in.

Grade A means an approved drug or several human randomized trials. Grade D means the evidence stops at cells and animals. Most popular research peptides sit at C or D.

What changed for peptides in 2026.

Dated, sourced, and checked against the agency page where one exists. The legal-status guide carries the full timeline.

  1. July 23, 2026

    FDA advisers vote 8 to 6 on BPC-157

    The Pharmacy Compounding Advisory Committee recommended adding BPC-157 to the list of bulk substances pharmacies may compound from. The vote does not bind the FDA, and it does not make BPC-157 legal to compound.

  2. April 2026

    Five peptides leave Category 2

    FDA now lists BPC-157, TB-500, CJC-1295, KPV and MOTS-c as nominations that were withdrawn. GHRP-2, GHRP-6, ipamorelin, kisspeptin-10 and MK-677 remain in Category 2.

    First oral GLP-1 pill for weight loss approved

    The FDA approved orforglipron (Foundayo) for chronic weight management. It is a small molecule, not a peptide, and it is taken by mouth once a day.

  4. February 6, 2026

    FDA moves against mass-marketed compounded GLP-1s

    The agency said it would restrict the GLP-1 ingredients used in mass-marketed compounded drugs. The semaglutide and tirzepatide shortages that allowed compounding ended in 2025.

Peptide tools

The math, done for you.

A vial labeled in mg, a draw written in mcg, a syringe marked in units. Most mixing errors start there. These tools show the arithmetic step by step. They give numbers, not dosing advice.

Frequently asked questions
Does Staate sell peptides?
No. Staate does not sell peptides, link to sellers or take affiliate payments. It is a free reference: each peptide page lists the published studies, the legal status and the known side effects, with a source for every claim.
Are peptides legal?
It depends on the peptide. Some are FDA-approved prescription drugs, such as semaglutide and tesamorelin. Others are approved only outside the US, some are still in clinical trials, and many are sold online as research chemicals that are not approved for human use. Each peptide page states its US status, whether pharmacies may compound it and whether WADA bans it in sport.
Why are dose tables behind a free account?
The tables record the doses that published trials and approved labels used, with the source for each row. They are a record of research, not dosing advice, so we show them to signed-in readers alongside that context. The account is free and needs no card.
How are peptides graded?
A means an approved drug or several human randomized trials. B means at least one human randomized trial. C means small or open-label human studies only. D means animal or cell data only. The grade measures how much human research exists, not whether it found a benefit; the evidence summary on each page says what the trials found.
Is this medical advice?
No. Staate explains published research for education. Decisions about starting, stopping or dosing any drug belong with a licensed clinician who knows your history.
