Research behind the blend
Three peptides, one verified vial.
BPC-157: a 2022 pharmacokinetic study in rats and beagle dogs found intramuscular BPC-157 reached 45 to 51 percent bioavailability in dogs. Research in rats found accelerated repair of transected Achilles tendon.
TB-500: in a rat full-thickness wound model, thymosin beta 4 increased reepithelialization by 42 percent at 4 days and as much as 61 percent at 7 days. Its active segment drives actin binding, cell migration and tissue repair.
GHK-Cu: reviews report collagen, elastin and glycosaminoglycan synthesis, with tissue-repair effects shown in skin and the foot pads of dogs.
