Sermorelin and BPC-157 Together: What Is Known

Sermorelin and BPC-157 taken together: what each one is, how each is regulated, and what is known about combining them.

Medically reviewed by Juan Pablo Frías, MD · · DisclosureUpdated
GHRH analogCompounded by prescriptionSermorelinGHRH analog once FDA-approved as Geref and since discontinued; in an uncontrolled pediatric study mean height velocity rose from 4.1 to 8.0 cm/yr after 6 months.[18]Growth hormoneGastric pentadecapeptidePCAC voted 8–6 for 503A (Jul 2026)BPC-157BPC-157, an experimental gastric pentadecapeptide, not an approved drug; human evidence is a few small uncontrolled reports, including complete symptom resolution in 10 of 12 patients in a bladder pilot.[15]Healing & recovery

WADAProhibited by WADA (S2.2.4)Sermorelin is named as a GHRH analogue in S2.2.4 (growth hormone releasing factors), prohibited at all times.Prohibited by WADA (S0)BPC-157 is named in S0 (non-approved substances), prohibited at all times, in and out of competition.
Anti-doping detection
  • A urine assay detects CJC-1295 and other GHRH analogues at very low concentrations.PMID 35298973
  • Labs expect GHRH analogues like CJC-1295 to be hard to find because of tiny urine concentrations; the study reports no detections in routine anti-doping samples.PMID 34665524
  • A 2023 method detects BPC-157 and five main metabolites in human urine at very low concentrations.PMID 37959764
  • A 2017 anti-doping lab method detects BPC 157 in urine; the peptide was stable in urine for at least 4 days.PMID 28035768
