interesting rodent data, almost no human data, both things are true
interesting rodent data, almost no human data, both things are true, which sounds obvious until you try to state the evidence for it.
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.
Short peptides in solution are subject to hydrolysis and, depending on sequence, oxidation. Storage state and time in solution are practical variables that this board almost never discusses.
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 me anything specific. Anything general I will probably get wrong.
best — the order this archive was captured in
Purity by area percent tells you the sample is homogeneous. Mass spectrometry tells you what the homogeneous thing is. For a short peptide, the second question is the one worth paying for.
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.
This. Mass spectrometry for identity, not just an area percent, because a pure something-else is still something else.

Agreed — cheap to make is a double-edged fact and it explains a lot about this corner of the market.
Was there identity confirmation, or only a purity figure?
Left up. It distinguishes rodent work from human work, which is the standard on this board.
Asked QYB for the theoretical mass alongside the certificate and they sent it without asking why.
ask for the mass spectrum, not just the purity number
Not convinced. A high purity figure with no identity confirmation tells you the sample is homogeneous, not that it is what you ordered.
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.
the tendon claims are the most repeated and the least evidenced
