Staff post. Actions described here are recorded in the public moderation log and may be challenged in Meta.

Anything not covered by a dedicated subcategory, including research-use-only material with no human data.

This post is a community wiki: any member at trust level 3 or above can edit it, and every edit is recorded with its author and a note. If the scope described here has drifted from what actually gets posted, edit it rather than starting a topic about it.

What belongs here

Questions specific to other compounds, with the units and the context stated.
Reports and datasets, with the collection method stated.
Disagreement about the substance, conducted in public.

What belongs elsewhere

Anything urgent belongs in Safety, immediately, and not here.
Anything about how this site works belongs in Meta.
Requests for a maintained page belong in Wiki requests.

Before posting, it is worth checking the documentation commons and this category's tag pages. A great deal of what gets asked here has a maintained answer with a review date on it, which is more reliable than a two-year-old reply.

Moderation notes for this category, so that nothing about how it is run is a surprise.

Topics get moved into and out of here regularly. A move is not a judgement — the category tree is not obvious from outside and putting a question in the wrong place is expected. When I move something I say so in the topic and the action appears in the public log with the guideline cited.

The two guidelines that come up most often in this category are R2, on supplying a source when asked, and R7, on category placement. Neither is used punitively.

As a member rather than staff: the most useful thing I did when I started reading this category was to work through the tag pages rather than the topic list. The topic list shows you what is recent. The tags show you what is settled.

Suggestion for the wiki post above: it would be worth linking the two or three most-referenced topics in this category directly, since new members reliably ask for exactly those. Happy to make the edit myself if nobody objects, with a revision note.

Colour in a lyophilised cake is worth noting for the less common compounds specifically, because some of them are genuinely not white and a member expecting white will report a problem that is not one.

Worth separating two things that post #2 runs together.

The tanning compounds carry a specific practical point that is not pharmacological: any change to a pigmented lesion is a reason to see a clinician, and that is not a matter of opinion or of dose.

Collapsed as off-topic by two members at trust level 3 or above

This follows post #4 rather than contradicting it.

Several compounds discussed here have no published human pharmacokinetics at all. That means half-life claims in circulation were derived from an animal model or from nothing.

Worth checking against a second source before it gets quoted onward.

Useful. I have added it to my own notes with the date on it.

Post #6 answers the question as asked. The question underneath it is different.

PT-141 was developed from the same family with a different receptor profile, and it has a considerably better documented human evidence base than most compounds discussed in this subcategory.

I have left out the parts I could not verify.

On post #6 — agreed on the reasoning, with one qualification.

Anything in this subcategory with a published trial behind it should be discussed separately from anything without one. Mixing them produces a discussion where the confident claims come from the compounds with the least evidence.

Reading it again, the caveat matters more than the finding.

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.

Posting it because the silence on this was starting to look like agreement.

Research use only, not approved for human use, and in this subcategory the compounds vary enormously in how much is known about them. It is worth establishing which end of that range a specific compound sits at before anything else.

It reads as pedantry until the day it does not.

Reading rather than contributing, but this is the most useful thread I have found on it.
