What a systematic review is, what a meta-analysis adds, why a paper titled "systematic review" sometimes isn't one, and what the published reviews of BPC-157, GHK-Cu, TB-500 and Cerebrolysin actually concluded.

Peptide names decoded: why it's called BPC-157, what INN stems like -relin and -glutide mean, how code names arise, and why a name never proves identity.
