Peptide stack interaction checker.

Curated reference pages for the most common community stacks. Each page covers the mechanism rationale, the standard protocol most users actually run, the honest read on evidence quality, and the shared risks worth flagging when two compounds touch overlapping pathways.

Not medical advice. Curated v1 covers 8 stacks. New entries ship as community practice consolidates.

Recovery + tissue repair
BPC-157 + TB-500 · recovery + tissue repair

The most common research-peptide recovery stack. BPC-157 for cytoprotection + angiogenesis; TB-500 for cell migration + actin remodeling. Combined for tendon, ligament, muscle injury.

GH + IGF-1 axis
Ipamorelin + CJC-1295 · GH-secretagogue stack

The default growth-hormone secretagogue stack. CJC-1295 primes pituitary somatotrophs via GHRH; ipamorelin triggers the pulse via the ghrelin axis. Combination produces larger GH bursts than either alone.

Gut + GI
BPC-157 + KPV · gut-healing protocol

Community gut-healing stack. BPC-157 for mucosal repair + cytoprotection; KPV for downstream anti-inflammatory cytokine modulation. Common in IBD-symptom and post-antibiotic protocols.

Cognitive + nootropic
Semax + Selank · Russian nootropic pair

Russian-developed nootropic pair. Semax for cognitive activation in the morning; selank for anxiolysis in the evening or as needed. Approved for use in Russia, not in Western markets.

Sleep architecture
DSIP + Ipamorelin · sleep + GH-pulse stack

Nighttime peptide stack. DSIP for slow-wave sleep enhancement; ipamorelin for the GH pulse coupled to slow-wave sleep. Community-validated for sleep architecture, not formally trialled.

Weight loss
Cagrilintide + Semaglutide (CagriSema) · next-gen weight loss

Novo Nordisk's next-gen weight-loss combination. Amylin-receptor agonism (cagrilintide) plus GLP-1 agonism (semaglutide) for synergistic gastric-emptying delay + central satiety amplification.

AOD-9604 + Ipamorelin + CJC-1295 · fat-loss + GH stack

Three-component fat-loss stack. AOD-9604 for direct lipolysis; ipamorelin + CJC-1295 for endogenous GH pulses driving lipid oxidation. Common in body-composition protocols.

Tirzepatide + BPC-157 · weight loss with recovery support

Common community pairing. Tirzepatide drives caloric deficit; BPC-157 supports gut tolerance + tissue repair through the muscle loss + activity changes that come with rapid weight loss.
