The peptide reference · 74 compounds mapped

Every peptide, graded by the evidence — not the hype.

A verified, plain-English reference for clinical peptides and metabolic therapies: regulatory status, human-trial data, and a tier rating for each compound. Built for providers and the patients they treat.

The rating system

Three tiers. Four evidence grades. No marketing.

Every compound is sorted by its real regulatory standing and the strength of the human data behind it — so a provider can see in two seconds where a therapy actually stands.

● TIER 1

FDA-approved / recognized

Approved products, or substances with established human-trial support. Prescribe and compound within the normal rules.

22 compounds in this tier
● TIER 2

Compoundable · emerging data

Lawfully compoundable under 503A/503B with a legitimate evidence base, but outside a full FDA approval. Use with informed consent.

5 compounds in this tier
● TIER 3

Information only

Research compounds with thin or preclinical-only human data, or an unsettled compounding status. Documented here for transparency — not a recommendation.

How to read this site

Compounding, in plain terms

Peptide legality turns on one framework most patients have never heard of. Here's the short version — the long version lives on every compound page.

01 / 503A

503A pharmacies

Compound patient-specific prescriptions. A peptide has to sit on an approved bulks list — or be an approved drug — to be made here legally. We flag each compound's 503A standing.

02 / 503B

503B outsourcing facilities

Make larger batches under FDA cGMP oversight for office use. Different list, different rules — a compound can qualify for one lane and not the other.

03 / The grade

Evidence grade A–D

Separate from legality: how good is the human data? Grade A is RCT-backed; D is mechanism or anecdote. Legal to compound and well-studied are not the same thing — we show both.
