ACE-031 vs GHRP-6
Both are discussed for muscle & performance. What this site records about each, side by side. Every figure is on the compound's own page with the source it came from.
| ACE-031 | GHRP-6 | |
|---|---|---|
| What it is | A myostatin trap that reached phase 2 in Duchenne muscular dystrophy and was stopped there. The muscle effects were real but never reached significance; the reason it stopped was nosebleeds and spider veins. | The oldest of the growth hormone releasing peptides, and the one with the strongest effect on hunger. That appetite stimulation is the defining fact about it. |
| EvidenceHow much human evidence exists, not how well it works. | Early human trials | Early human trials |
| Regulatory statusReviewed 2026-09-01 | Never approved anywhere. Development was halted in 2011 on safety grounds and permanently discontinued in 2013. Prohibited in sport at all times by WADA as a myostatin inhibitor. Material sold as a research chemical is not the clinical product and carries none of the trial's monitoring. | Not approved for human use in any jurisdiction. Studied in humans in early-phase research decades ago; development was not carried through to approval. Sold only as a research chemical. |

This page is educational. It describes what published research reports, not what you should do. Peptides discussed here are largely not approved for human use, and nothing on BioAlmanac is medical advice. Nothing here ranks these two against each other. A table can show that one has more human evidence behind it or costs less per milligram; neither of those is a recommendation, and the right comparison for any person is one their doctor makes with them.
