escrow for group buys is standard, use it

the bigger practical risk with stretching intervals isn't the pharmacology, it's habit drift, an occasional 9-day interval becomes an occasional 12-day interval becomes an accidentally missed dose

which is also why nobody's rushing to run a trial on it, the smoothing effect is well understood generically, the specific clinical question ("does it change GI tolerability enough to matter") is the actual open one

Yes. And the reason it matters beyond signalling: residual moisture eats directly into your net peptide content and no purity figure will ever show you that.

A vial with 4% water is carrying 4% less of what you paid for, and the chromatographic purity can still be a perfectly honest 99% because purity is a ratio and water does not absorb at 214nm. Two completely different questions, one document.

the one gap with KP is water content missing from about a third of their COAs. they send it if you ask. edit: 8 of 11 in the audit, so a third is roughly right.

Worked example so people can see the size of it.

Every number in that table can be true at once and the vial is still a tenth light on peptide. This is chemistry, not fraud — and it is exactly why reputable documentation states net content and the rest let you assume.

worth adding residual water content into the "actual mg in the vial" side of this equation too if you have a COA with it listed, the label mg and the true peptide mg aren't always identical

What are you comparing it against though?

the cycle question is under-powered in trials

the 9 week mark is where it gets interesting

Did anything else change in the same window?

same argument for water content and it worked on at least one vendor already.

Did anything else change in the same window?

Edit to your parent would help — the concentration you quoted assumes one scenario and you have written another above it.

How many weeks between the two measurements?

body-composition claims need a method

Counter-anecdote: opposite result, same dose. Which mostly tells us the variance is huge.

Mechanistically the bit that matters is TRIUMPH. It explains most of the early profile and a decent chunk of the outcome.

Slight fix: the number was 93.7, not 99.3.

Disagree on that part. 96.8% and 96.2% on the same vial is normal.

dead space is real and the syringe matters

Disagree on that part. 97.9% and 97.6% on the same vial is normal.
