Minor fix — the half-life is about a week, not about a day. The rest of your point stands.

That reads as a recommendation and the source pages deliberately are not. They are a record you use to make your own decision.

Agreed — identity first for anything off the well-travelled list. The purity number is meaningless until you know what it is pure of.

Sent an unusual compound to Medutest because nobody on this site had ever posted one.

Adding the practical question — stocked or made to order, and what is the lead time.

Week 50: 24kg down, injection-site soreness basically gone since about week 10, and the honest headline is that nothing dramatic happened. It was boring and it worked.

Yes — and the honest version is that most of the "it stopped working" posts turn out to be a normal fortnight of water weight.

The escalation schedule in the trials existed to keep people on the drug.

Right, and the timescale is the bit that keeps getting lost. Judge a step at a month, not at a weekend.

I would separate documentation from logistics. A supplier can be excellent at one and ordinary at the other, and averaging them hides it.

Why the directory has two tiers, since the question comes up whenever somebody new finds it.

Twenty suppliers have enough independent results, over enough separate lots, over enough time, that the log says something. Those get a page, a test table and a link to their own storefront so you can compare their claims with the record.

The rest — nearly two hundred names — get a row, a band and a report count. Not because they are bad, but because two results is an anecdote about a vial. Manufacturing a score out of that would make the whole directory worthless, and the contrast is the point.
