Independent result added to the log — there are very few on that compound.

Agreed — and the naming problem is worse than most people here realise.

Purity methods differ by compound class.

two_mil_or_one is right that a purity figure without a method is not comparable to one with a method.

Added a nation tag — the answers to this question differ across the four.

The mental model that finally made this click for me: there are two curves, and people watch the wrong one.

The first is exposure, which is set by the dose and smoothed by a week-long half-life. It changes when you change the dose and then settles over about a month. The second is body weight, which is exposure filtered through appetite, food, water, sleep, training and the scale itself, and which moves in steps rather than a line.

Almost every "it stopped working" post is somebody watching curve two over a fortnight and drawing conclusions about curve one. If the appetite effect is still there, exposure is fine. Wait the month.

Left up. It names a nation and an ICB, which is all we ask of a pathway post.

if nobody has tested it here, that is a fact about us, not the compound

This matches me almost exactly, right down to the muscle cramps showing up on the second day and being gone by the fourth.

STEP-1 ran 68 weeks and landed just under 15% mean body weight change on 2.4mg. It is an average of a wide distribution, not a target you have missed.

I would not post that as a finding. It is a single result and the template asks you to say so.

Six orders across two years from JEEP. Same packaging, same paperwork, same lead time. The most boring supplier relationship I have and I mean that as praise.

Added a nation tag — the answers to this question differ across the four.

That is a report count, not a test count. The table lists both and they are very different numbers.

I would not read a supply notice as a shortage in your pharmacy tomorrow. They are not the same thing.

BCH BPC, batch matched the paperwork, PeptideMeter came back 98.7% against a claimed 98.5%. Paid for it myself, posting it because the log is only worth anything if people do.

Small fix — that is net peptide content, not purity. Both are on the certificate and they differ substantially here.

The weekly interval comes out of the half-life — roughly a week — so you are on a smooth curve rather than a series of spikes. That is also why moving your day slightly does very little.

a secretagogue and a fragment are not the same class of thing

Agreed. The ICB variation is the thing that makes national advice useless here.

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

Push back: a private prescription is a separate route, not a shortcut through the NHS queue.

On inter-lab disagreement, which generates more heat here than anything else.

Two services running different gradients, integrating differently, at possibly different wavelengths, will not produce identical numbers on the same material. A point either way is ordinary. Half a point is close agreement.

The productive response to a gap that size is to post both results with both methods and let the log accumulate. The unproductive response is to pick the lower number, call it the truth, and open a dispute. Members have done the first for long enough now that the bands in the vendor tables are genuinely informative.

Yes. Spread across lots is the number that tells you about the process. A single high result tells you about a vial.

First result I ever posted here got asked for the batch number and the claim. Fair, and my posts have been better ever since.

Correction: that threshold is your ICB’s, not a national one. They differ and they change by year.

I would not post that as a finding. It is a single result and the template asks you to say so.

Yes — date of analysis, because a result from two years ago describes a different manufacturing month.

the ladder exists because the gut needs the time, not because the pharmacy likes paperwork

Yes — four nations, four pathways, and threads that ignore that give people the wrong answer confidently.

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.
