The catalogue is organised by research area rather than by brand. Growth-hormone-axis peptides (GHRH analogues such as sermorelin and tesamorelin, and ghrelin-receptor agonists such as ipamorelin and GHRP-2) are studied as receptor tools for pituitary signalling. Incretin-receptor analogues (semaglutide, tirzepatide, retatrutide, cagrilintide) are long-acting modified peptides used in receptor-pharmacology work. The short-sequence group covers small signalling peptides such as kisspeptin-10, gonadorelin and oxytocin, whose native receptors are well characterised. The repair group covers fragments such as BPC-157 and TB-500 that are mainly described in preclinical literature. Frequently asked questions Does 99% HPLC purity mean 99% of the vial weight is peptide? No. HPLC purity is a ratio of detected peak areas. Counter-ions and water add weight without appearing as impurities. What test gives peptide content? Quantitative amino acid analysis or nitrogen analysis, reported separately from HPLC purity. The short answer HPLC purity answers: of the material the detector sees, how much is the target peptide? Peptide content (net peptide content) answers: of the powder’s total weight, how much is peptide? They are different numbers, and a vial can be high on one and lower on the other [1][2].
