BPC-157, TB-500 (thymosin β4 fragment), B7-33, PEG-MGF. Soft-tissue, tendon-ligament, gastrointestinal-mucosa, and vascular-repair research peptides.
Who sources this class & for what
Repair peptides — BPC-157, TB-500, B7-33, PEG-MGF — ship primarily to research labs studying tissue-repair, gastrointestinal-mucosa, tendon-ligament, and vascular-endothelial models. The synthesis itself is reliable, but analytical confirmation is where suppliers differ: buyers qualifying a new source should request sequence verification by tandem MS on the first lot and compare against the labelled sequence directly.
