Research Peptide Comparison
BPC-157 is a synthetic 15-amino-acid peptide derived from human gastric juice protein, with preclinical research documenting roles in tendon and ligament repair, gut mucosal protection, and angiogenic signalling through NO-dependent and growth factor-mediated pathways. SLU-PP-332 is a small-molecule synthetic agonist of the oestrogen-related receptors ERRα and ERRγ — nuclear receptor transcription factors that regulate oxidative metabolism, mitochondrial biogenesis, and skeletal muscle fibre-type switching — positioning it as a research tool in the emerging category of exercise-mimetic compounds. The mechanistic contrast between these two research chemicals is pronounced: BPC-157 operates primarily via extracellular repair and vascular signalling, while SLU-PP-332 targets intranuclear transcriptional programmes governing cellular energy homeostasis.
BPC-157 (Body Protection Compound) is a synthetic pentadecapeptide derived from a protective protein found in human gastric juice. Investigated for its role in upregulating angiogenic pathways, modulating nitric oxide signalling and influencing growth-factor expression at sites of tissue injury, the sequence is widely cited across musculoskeletal, gastrointestinal and gut-brain axis studies.
Compared to SLU-PP-332 5mg, BPC-157 5mg is priced at £14.49 with 99%+ verified purity. Its CAS registry number is 137525-51-0. It has a molecular weight of 1419.53 g/mol.
BPC-157 5mg is available in 5mg, 10mg and ships with a full Certificate of Analysis from Janoshik Analytical. At £25.50 less than SLU-PP-332 5mg, it is the more affordable option in this comparison.
SLU-PP-332 is a small-molecule selective pan-agonist of the oestrogen-related receptors (ERRα, ERRβ and ERRγ), orphan nuclear receptors that regulate mitochondrial biogenesis, oxidative metabolism and skeletal muscle endurance programmes. By engaging all three ERR subtypes it has emerged as a leading exercise-mimetic research tool for interrogating metabolic adaptation and oxidative capacity.
Compared to BPC-157 5mg, SLU-PP-332 5mg is priced at £39.99 with 99%+ verified purity. It has a molecular weight of 438.52 g/mol.
SLU-PP-332 5mg is available in single size and ships with a full Certificate of Analysis from Janoshik Analytical. It is priced £25.50 higher than BPC-157 5mg.
