It is one of the best-known short peptide references in discussions around gastric peptide biology, tissue-signalling models, nitric-oxide pathways, and extracellular matrix research

Lyophilized peptides BPC-157, TB-500, GHK-Cu, semaglutide, tirzepatide, and others are supplied as freeze-dried powder and require reconstitution with a diluent before use
Reported applications include NNMT enzyme inhibition assays measuring 1-methylnicotinamide formation or S-adenosylhomocysteine release, intracellular target-engagement assays in differentiated 3T3-L1 adipocytes where 5-Amino-1MQ reduced intracellular 1-methylnicotinamide with an EC near 2.3 M (Neelakantan et al., Biochem Pharmacol, 2018), membrane permeability and Caco-2 transport characterisation, methyltransferase selectivity panels covering COMT, DNMT1 and PRMT3, and rodent studies of NNMT inhibition in adipose tissue and liver following the antisense knockdown work of Kraus and colleagues (Nature, 2014)
