why does nobody talk about tendon
The title is the whole question — why does nobody talk about tendon — but here is why I am asking. Kept a reconstituted vial too long out of curiosity and learned something about solution stability I would rather have read. Assumed regulatory status was static and it was not. Checked again this year and the answer…
The published literature is overwhelmingly preclinical, largely in rodent models. Translating a rodent result into a human expectation is not a small step, and almost every confident claim here takes it silently.
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.
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.
pentadecapeptide, fifteen residues, and the sequence is public
Cosigning that the papers are more modest than the summaries of them. That is true across this whole site and especially here.
Was there identity confirmation, or only a purity figure?
identity testing matters more here than purity does
The published literature is overwhelmingly preclinical, largely in rodent models.
Adding the standing caveat — research material is not approved for human use, wherever you are.
Correction: that study was in rodents. Worth stating explicitly since the thread has been reading it as clinical.
Reconstituted or powder, and how long has it been in solution?
I would not extrapolate a mechanism from a model system to a person in one step, which is what that comment does.
short peptides are cheap, which cuts both ways
That claim traces back to a single preclinical paper that says something considerably narrower.
preclinical enthusiasm is not clinical evidence
Small fix — fifteen residues, not seventeen. The sequence is public and easy to check.
the tendon claims are the most repeated and the least evidenced
