BPC-157, GH secretagogues, thymic peptides, dosing and safety reads.
Most of the peptides we cover live entirely on the grey market, with names that promise more than the data delivers. Thymosin alpha-1 (Tα1) is different, and that difference matters.
Few peptides carry a name that sells itself like this one. DSIP — delta sleep-inducing peptide — was pulled from the blood of sleeping rabbits in the 1970s and christened for the deep, slow brain waves it seemed to summon.
Let me give you the blunt version first. BPC-157 — Body Protection Compound-157 — is the peptide that the gut-repair corner of the internet treats as a miracle: a leaky-gut cure, an ulcer-healer, an IBD fixer you can order as a “research chemical” and injec…
Every so often a peptide comes along where the human data is genuinely more interesting than the marketing, and the marketing still manages to run past it. Kisspeptin is that peptide.
Almost everything sold in the peptide space is unapproved and untested in humans. Bremelanotide is the exception: it cleared two phase-3 trials and won FDA approval as Vyleesi for low desire in women. That is real, and rare.
SS-31 — the lab name for elamipretide, also called MTP-131 and Bendavia — is the rare biohacking peptide that went the whole way through pharmaceutical development.
It is the new viral fat-loss compound — an NNMT inhibitor that the marketing says shrinks fat cells, raises NAD+, and rebuilds your metabolism. The mechanism is real and the mouse data is real. The human data does not exist.
KPV is a three-amino-acid fragment of a hormone your body already makes, and it has built a genuinely interesting anti-inflammatory case — in petri dishes and in mice.
Epitalon is the headline anti-aging peptide — the one with the telomerase story attached. The mechanism is real, and in 2025 an independent lab finally replicated it. The human longevity claims are a different matter. Here is the honest map.
Semax is a synthetic peptide built from a fragment of a stress hormone, approved in Russia as an intranasal drug for stroke and brain circulatory disorders, and sold in the West as an unapproved “research peptide” for focus and memory.
A 12-amino-acid peptide called BRP cut appetite by up to half in mice and pigs — and, unlike the drugs it’s being compared to, it did it without nausea and without touching lean muscle.
Vesugen is a three-amino-acid peptide from the Russian bioregulator school — synthesized to mimic active fragments of vascular tissue extracts. The lab evidence is unusually mechanistic; the clinical evidence is small but specific.
The practical companion to the Vesugen mechanism explainer: forms, doses, course lengths, side effects, contraindications, and how it stacks with other peptide bioregulators. What the published evidence and Russian clinical convention actually support.
Every time I post about BPC-157, the same question lands in the DMs: doesn’t it feed cancer? The honest answer is that there’s a real theoretical concern, and an equally real context that almost nobody on either side bothers to …
GHRP-6 — Growth Hormone Releasing Peptide-6 — binds the ghrelin receptor to amplify pulsatile GH output from the pituitary. It is one of the most researched growth hormone secretagogues (GHSs) in the class, and also one of the most misread.
The peptide community has a stacking problem. Six compounds, rotated through a single morning, in pursuit of a goal the user can’t actually articulate.
Every semaglutide and tirzepatide user loses 20–40% of their dropped weight as lean tissue — muscle, bone density, and the facial volume that defines how a face ages. That isn’t a side effect to manage around.
Every peptide in the current research landscape was designed by chemists or discovered in tissues. MOTS-c is different: it's encoded directly in the 12S rRNA region of mitochondrial DNA — your cell's ancient bacterial endosymbiont is producing a signaling p…
Every major GLP-1 weight-loss trial — STEP 1 with semaglutide, SURMOUNT-1 with tirzepatide — costs the user 20 to 40 percent of their lost weight as lean mass, including facial volume.
