Peer-reviewed evidence, summarized — never interpreted
What the research says about vesugen
A neutral summary of the peer-reviewed literature on vesugen, a synthetic Lys-Glu-Asp tripeptide bioregulator studied almost entirely by a single research lineage in animal and in-vitro models, with one small uncontrolled human observational study and no controlled human trials. Research use only.
Preclinical onlyWhat the research says about prostamax
A neutral summary of the peer-reviewed literature on prostamax, a synthetic Lys-Glu-Asp-Pro short-peptide bioregulator studied almost entirely by a single research lineage in animal and in-vitro models, including cultures of ex-vivo human lymphocytes from elderly donors. There are no controlled human trials. Research use only.

Every summary paraphrased from the published abstract, every number traceable to it, every paper linked on PubMed.
● How pepmg works
The math ranks. Money doesn't.
We read the stores
Every price is read directly from each vendor's own live store, daily. Public data only — no logins, no scraping behind gates.
We normalize to $/mg
Vial sizes, multi-packs, blends, bulk and outliers are parsed or flagged so comparisons are apples-to-apples. The math is published.
We rank by the math
Sort is strictly $/mg ascending. A commission never moves a row — paid links are labeled on the row and ranked identically.
The pepmg pledge
- 0 paid placements — no vendor can buy a rank, ever
- Every paid link labeled — affiliate status shown beside the action
- Receipts on every price — when and where we captured it
- COAs classified, never certified — we link what labs publish
- Research use only — no dosing, no medical advice
- Correctable — we'd rather be corrected than wrong
