What is a secretagogue? The meaning and origin of the word, the main classes from growth hormone and insulin to gastric acid, how secretion is measured in the lab, and what the label leaves out.
Bradford vs BCA assay: how each protein assay works, why the standard skews results, and why both can mislead you with short synthetic peptides.
Peptide purity explained: what an HPLC area-per-cent figure measures, why it is not net peptide content or identity, and what a high number can hide.
FDA published substance reviews for seven research peptides in July 2026. What they found on human data for BPC-157, KPV, MOTS-c and more.
A goods-in checklist for research peptides: batch matching, the recognised freeze-dried cake defects, and what appearance cannot tell you.
A single purity figure underdetermines a co-formulated peptide vial. What area percent measures, why it is not the component ratio.
N-acetyl peptides explained: the fixed 42 Da mass shift, why an acetate salt is not N-acetylation, and what is actually published.
GHK-Cu and AHK-Cu differ by one methyl group. One has a human randomised trial behind it; the other has a single ex-vivo study.
The FDA registers TB-500 as a seven-residue fragment, not full-length thymosin beta-4. Why only a measured mass tells the two vials apart.
What a lot number is in the regulations the convention comes from, how lot and batch differ, what records have to sit behind the number, how a retest date differs from an expiry date, and what a lot number cannot prove on its own.
