How to research a compound with no human data without deceiving yourself

Asking directly, because I could not find a straight answer: How to research a compound with no human data without deceiving yourself

Session topic: STEP 2 (Lancet, 2021). Please read it before posting; the discussion is much better when everyone has.

The question I would like us to start with is what the trial set out to estimate, rather than what it found. Once that is on the table we can talk about whether the design could have answered it, and only then about the numbers.

Specific things I would like covered: the population and how far it generalises, how discontinuation was handled, whether the comparator was a fair one, and what the absolute rather than relative effect looks like.

I will summarise at the end and the summary will feed the relevant digest page.

Coming back to post #8, because the follow-up matters more than the original answer.

Melanocortin agonists: mechanism involves the melanocortin-4 receptor pathway that regulates appetite. The documented adverse profile includes blood pressure elevation and erections of sustained duration, the second of which is specific enough that it is the first thing worth mentioning.

Two things before anyone answers the substance.

First, the context in the first post is clear and specific. Second, the question is framed so that an answer can actually address it. Both are the norm here and both matter more than they sound.

For anyone arriving from a search: the marked solution above is the direct answer, and the replies underneath it add the caveats that make it safe to use.

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.

I read post #66 twice before replying, because I had assumed the opposite.

Reading a supplier's product description as a marketing document: that is exactly what it is. The hyperbole, the mechanism written as fact, the theoretical benefits stated as established benefits — all of that is marketing. Treat it as such and separate it from evidence where evidence exists.

How to research a compound with no human data: mechanistic plausibility is one input. Preclinical data is another. The honest position is that you are reasoning from theory, not from evidence, and the track record of such reasoning is unimpressive when tested against actual outcomes.

On post #99 — agreed on the reasoning, with one qualification.

Naming conventions for research peptides cause confusion because suppliers do not follow a standard. The same compound gets different names from different suppliers. If you are researching something, confirming the sequence or mass is more reliable than confirming the name.
