Growth Hormone
CJC-1295 / Ipamorelin 5mg / 5mg
The classic secretagogue pairing. CJC-1295 raises baseline GH release, ipamorelin adds a clean pulse without touching cortisol or prolactin.
from$180

Double-strength CJC-1295 with ipamorelin — the long-block version of the standard pairing.
from$180
Growth Hormone
CJC-1295 without DAC 5mg
Also called Mod GRF (1-29). Short half-life, so it produces a pulse rather than a sustained elevation — the version most people pair with ipamorelin.
$140
Growth Hormone
CJC-1295 with DAC 5mg
The drug-affinity-complex version, with a far longer half-life. Fewer injections, a steadier baseline, less pulsatility.
$140
Growth Hormone
Ipamorelin 10mg
The most selective GH secretagogue in common use. Minimal effect on cortisol, prolactin or appetite, which is why it is the default pairing partner.
