Research Applications
These peptides have been studied in various research contexts related to muscle growth.
Mechanism of Action
The GH Axis Pathway
Peptide Binds Receptor
GHRH-R or GHSR-1a on pituitary somatotrophs
GH Pulse Released
Amplitude + frequency both increase
IGF-1 Secretion
Liver and peripheral tissue respond
Muscle Adaptation
Satellite cell activation & myofibril growth
Two Complementary Classes
GHRH Analogues vs Ghrelin Mimetics
GHRH Analogues
Increase GH pulse amplitude
CJC-1295 (with DAC)
6–8 day half-life via albumin binding. Sustained baseline GH elevation.
CJC-1295 (no DAC)
Short-pulse physiological rhythm. Mimics natural GHRH bursts.
Sermorelin Acetate
Gentle, well-studied secretagogue. Strong safety profile in research.
Tesamorelin
Documented visceral fat reduction + muscle maintenance.
Ghrelin Mimetics
Increase GH pulse frequency
Ipamorelin
Most selective class member. Minimal cortisol or prolactin elevation.
GHRP-2
Stronger GH spike. Stimulates appetite — useful for mass-building phases.
MK-677 (Oral)
24-hour GH + IGF-1 elevation. Bioavailable oral capsule form.
Research Finding
Combination Protocols Produce Synergistic Results
Pairing a GHRH analogue with a ghrelin mimetic stimulates both GH pulse amplitude and frequency simultaneously — producing effects neither compound achieves in isolation.
1×
GHRH Alone
baseline GH release
1.5×
Ghrelin Alone
above baseline
4–6×
Combined Stack
synergistic release
Supporting Compounds
Recovery & Anabolic Support Peptides
BPC-157
Tendon & ligament repair, angiogenesis, gut health
TB-500
Systemic cell migration, actin polymerization, anti-inflammatory
IGF-1 LR3
Direct myocyte signaling, satellite cell activation
ACE-031
Myostatin inhibition — genetic ceiling bypass in research
