This is a side-by-side of what is documented, not a ranking. Different compounds are studied for different things, in different people, at different amounts. A row that looks stronger for one compound does not make it the better choice for anyone.

| What is not known | No completed human clinical trial administering Ac-SDKP itself (at any dose or route) was identified in the sources reviewed for this entry. A 2006 published review (Cavasin, PMID 17083265) explicitly states no clinical trial data existed supporting its use for cardiac healing at that time,... | What BPC-157 binds to. No receptor has been identified, no binding affinity measured, and no knockout or knockdown experiment has shown a required target, after roughly 230 papers. Whether it reaches the circulation in a human being. The only human measurement by any route found... |
