sequence — 10 things I got wrong before I got it right

Caution Clean Column ×2 Cold Box ×1

sequence — 10 things I got wrong before I got it right. Not a hot take, just something I have not seen said plainly here.

Every claim I could trace in this board went back to about four papers. That was a sobering afternoon.

Asked SWB for the theoretical mass alongside the certificate and they sent it without asking why.

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

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

It is a fifteen-residue peptide with a published sequence, which makes synthesis straightforward and makes identity verification the meaningful test rather than an optional extra.

identity, quantity, stability — three separate questions

What method produced that purity number?

Added a jurisdiction tag to the regulatory question. The answer differs and has changed.

Correction: that study was in rodents. Worth stating explicitly since the thread has been reading it as clinical.

Was there identity confirmation, or only a purity figure?

read the actual papers, they are more modest than the summaries

pentadecapeptide, fifteen residues, and the sequence is public

What jurisdiction are you asking about? The answer has changed in several.

u/ms_fragmenter26 points·1 year ago

Right, and regulatory status has genuinely moved in several jurisdictions. Answers from three years ago may be wrong now.

Regulatory classification differs between jurisdictions and has changed in several of them recently. Any answer to a status question needs a place and a date attached.

Push back: "no reported harms" in a literature with almost no human trials is not a safety finding.

u/teodor_szabo31 points·1 year ago

Do you have the mass spectrum?

replysharereportpermalink
u/arne_ilunga22 points·1 year ago·edited

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.

Has anyone posted an independent result on that batch?

no clinical trial has established what these threads assert

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.
