Second pass at: How to research a compound with no human data without deceiving yourself

Thymosin alpha-1 has a regulatory history in several jurisdictions and a real clinical literature, which puts it in a different evidential category from most of its neighbours here.

I would put this at better than even and not much better.

Research-use-only status is a legal classification, not a safety classification. It means the compound is sold for laboratory use and not for human consumption or treatment. The label does not tell you whether the molecule is safe, efficacious, or what its effects are.

I have deliberately not rounded that, because the rounding is where the argument starts.

Where a compound has a legitimate pharmaceutical form somewhere in the world, the labelling for that form is usually the single most useful document available and is almost never consulted here.

AOD-9604 is a fragment of human growth hormone and has been discussed as a potential weight-loss agent based on theoretical mechanism. The fragment hypothesis — that the fragment retains a specific property of the intact hormone — is not settled for this compound.

Stating my assumptions rather than smuggling them in.

This subcategory exists because some people will research compounds outside the main groups discussed here. The standard of evidence and honesty about its limits applies to everything discussed, not just to approved drugs.

Written from notes rather than memory, which is why the numbers are specific.

Worth stating the null on research a compound before we explain it: the observation may be nothing. That possibility deserves a sentence and usually does not get one.

Worth separating two things that post #57 runs together.

Research-use-only status is a legal classification, not a safety classification. It means the compound is sold for laboratory use and not for human consumption or treatment. The label does not tell you whether the molecule is safe, efficacious, or what its effects are.

On post #61 — agreed on the reasoning, with one qualification.

Building on post #68 rather than restating it.

I read the earlier replies on research a compound twice before writing this, because I had assumed the opposite and wanted to be sure I was disagreeing with what was said rather than what I expected.
