Every major peptide and compound people ask about, grouped by goal and rated by how much human evidence actually backs it. Neutral, no hype, no doses. Free to use and free to download.
This is the strict version of the reference below. Every count was checked directly on PubMed and ClinicalTrials.gov as of September 2026, for the compounds audited so far. The directory further down is broader and simpler; this table is the sourced, checkable core, and it answers one question honestly: how much human evidence supports actually taking each compound, rather than measuring the body's own version of it.
| Compound | PubMed papers | Human trials in people | Registered trial giving it to people | Results | Evidence rating |
|---|---|---|---|---|---|
| Epitalon / Epithalamin | ~50 | 2 RCTs, both on epithalamin (the pineal extract), one research group | Pre-registry era; none current | Yes, small and single-group | Preliminary |
| MOTS-c | 255 | 5, all measure the body's own MOTS-c; none administer it | 1 — NCT07505745, Shenzhen, recruiting | None | Registered only |
| TB-500 | 26 | 0 | 1 — NCT07487363, Shenzhen, recruiting (heart biomarkers) | None | Registered only |
| Thymosin β-4 (not TB-500) | 1,055 | 7, for dry eye and venous ulcers | Different molecule from TB-500 | Yes (dry eye, ulcers) | Established, other use |
| Semax | 231 | 4, all Russian-language (stroke, motor neuron disease, optic nerve) | 0 registered anywhere | Russian-language only | Preliminary |
| GHK-Cu | 99 | 0 | 1 — NCT07437586, Shenzhen, topical gel, recruiting | None | None |
Three of the four registered trials that actually administer these compounds to people are in Shenzhen, China, all recruiting, none with posted results as of September 2026. These trials are recruiting and will eventually report, so the table is dated and re-checked quarterly. Last updated September 13, 2026.
The verified audit ends here. The six compounds in the table above were checked directly against PubMed and ClinicalTrials.gov on September 13, 2026. Everything below is a broad orientation directory, a map of what people ask about, not an evidence assessment. The colored dots are a rough, unverified guide, most of these compounds have not been through the evidence audit, and a dot should not be read as a verified rating.
Unverified. A broad map of the compounds people discuss, grouped by goal, to help you find a topic. It is not a rating of how well any of them works.
Listed as talked-about, not endorsements. Combinations are rarely studied for safety.
