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 beyond the biology.
Read →Why Peptide Dosing in Studies Rarely Matches Marketing
The doses in the research and the doses on the label are often worlds apart.
Read →Adipotide: A Cautionary Tale in Peptide Development
A fat-loss peptide that shrank monkeys 11% in 28 days — and then failed human trials on kidney safety.
Read →Humanin: A Mitochondrial-Derived Peptide Worth Watching
A mitochondrial peptide ~3x higher in centenarians' offspring — with real biology but no human trials yet.
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.
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.
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.
Read →Peptides for Skin: Topical vs Injected Evidence
Where cosmetic peptides have a real, modest case, and where injectable claims sprint past the data.
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 aren't. The contrast is instructive.
