Peptides and Cancer Risk: Untangling a Complicated Question
Growth-signaling peptides raise legitimate questions the marketing rarely addresses. Here is what the IGF-1 evidence actually shows.
Read →The Real Risks of Sourcing Peptides Online
Impurities, immunogenicity, and unverifiable purity claims — the FDA-flagged dangers that sit beyond the biology of the molecule.
Read →Why Peptide Dosing in Studies Rarely Matches Marketing
The doses in the research and the doses on the label are often worlds apart. Why that gap exists, and what it means for reading any claim.
Read →Adipotide: A Cautionary Tale in Peptide Development
A fat-loss peptide that shrank monkeys 11% in 28 days, then failed human trials on kidney safety. What the case should teach.
Read →Humanin: A Mitochondrial-Derived Peptide Worth Watching
A mitochondrial peptide about 3x higher in centenarians' offspring — real biology, but no human trials yet. Why it is watched.
Read →Growth Hormone Secretagogues: Do They Beat Direct HGH?
Secretagogues raise GH pulses 70-100% but leave serum GH far below injected levels, with thin outcome data behind either.
Read →SS-31 (Elamipretide): The Mitochondrial Peptide in Trials
A genuinely investigational compound that has run real clinical trials — and largely missed its primary endpoints. A useful benchmark.
Read →Compounded Peptides and the FDA's Shifting Stance
The FDA's 503A bulk-substance categories keep moving under compounded peptides like BPC-157. What changed, and what it means for access.
Read →5-Amino-1MQ: NNMT Inhibition and the Hype Cycle
A metabolic target with real rodent data, a clean mechanism, and zero published human efficacy trials. How the hype outran it.
Read →Peptides for Skin: Topical vs Injected Evidence
Where cosmetic peptides have a real, modest case, and where injectable claims sprint past the data. The topical-versus-systemic gap.
Read →LL-37: The Antimicrobial Peptide Behind the Buzz
A real part of human immunity — and one implicated in autoimmune disease, marketed in ways the evidence doesn't support.
Read →Creatine vs Peptides for Recovery: Where the Evidence Stands
One is among the most-studied supplements ever; the others mostly are not. The contrast is instructive for judging any claim.
