Independent vendor rankings, peptide price comparison, and evidence-graded research profiles in one place. Source-linked data, not vague claims.
Vendor reviews
Vendors ranked by our own scoring model — combining trust evidence, pricing coverage, and third-party review data.
Consistently praised for product quality, dispatch speed and customer service.

Research library
Each profile grades the strength of published evidence and tracks how much vendors charge.
Gastric pentadecapeptide studied mostly in rodent tendon and gut healing models.
Thymosin beta-4 fragment examined in preclinical wound and cardiac repair work.
GLP-1 receptor agonist with a large human clinical trial record in metabolic research.
Dual GIP/GLP-1 agonist studied in large randomized metabolic endpoints.
Selective growth hormone secretagogue with limited but consistent early human data.
GHRH analogue often paired with secretagogues in pulsatile release research.
How scoring works
Every score is rebuilt daily from the same inputs, so a vendor cannot buy its way up the board.
How much of a catalog has third-party certificates that actually resolve at the testing lab.
How many products have tracked, current prices we can compare across the market.
Independent review scores contribute as bonus signals, never as gatekeepers.
