Retatrutide: Drug or Biologic? The Lilly v. FDA Case Explained
A single amino acid separates two regulatory pathways worth years of market exclusivity. Here is what the Lilly v. FDA case is about and why the wider peptide field is…
Semax vs Selank: Two Neuropeptides Compared
Two heptapeptides from the same laboratory, built on different natural peptides. How Semax and Selank differ in structure and research focus.
CJC-1295 With DAC vs No DAC: What the Difference Means
Two versions of the same GHRH analogue, separated by one chemical addition. Here is what DAC is and why it matters in research.
MOTS-c and SS-31: Mitochondrial Peptides in Research
Two very different peptides linked by one organelle: a signalling peptide encoded by mitochondrial DNA, and a small peptide that targets the inner mitochondrial membrane.
