stalled for 9 weeks at 1.0mg and I refuse to panic this time

Question

stalled for 9 weeks at 1.0mg and I refuse to panic this time. Making the case below, and I expect to lose some of it in the comments.

Numbers, in the order they matter: 9 weeks and 1.0mg.

Paid for identity confirmation rather than just purity for the first time here. Worth it, and it is not the default on most certificates.

Ask for the theoretical mass alongside the measured one. It is a one-line addition to a certificate and it converts a purity claim into an identity claim.

Happy to answer the boring questions. Those are usually the ones worth asking.

Research-use-only material is not approved for human use. In this board that is not a formality — it is the reason the clinical evidence base is as thin as it is.

Went and read the primary rodent papers after arguing about a summary for a week. They are much narrower than the threads suggest.

Agreed — and the preclinical to clinical gap is where nearly all the overclaiming happens.

Yes — the rodent literature is real and it is rodent literature. The gap to a human claim is enormous and it gets crossed in one sentence here.

Careful. Regulatory status differs by jurisdiction and has changed; a confident global statement is going to be wrong somewhere.

Was there identity confirmation, or only a purity figure?

slow_logbook_ftw is right that a pure something-else is still something else.

slow_logbook_ftw is right that a pure something-else is still something else.

This is the point that should be at the top of every thread here. Identity first.

preclinical enthusiasm is not clinical evidence

ask for the mass spectrum, not just the purity number

About c/bpc157

BPC-157 as it actually is: a pentadecapeptide with a genuinely interesting rodent tendon-and-gut literature, near-zero controlled human data, a naming and sequence mess in the supply chain, and a regulatory status that changed sharply in several countries.
