Stacks Well With
CJC-1295 (no DAC) / Mod GRF 1-29
Shorter-acting GH booster that releases growth hormone in natural pulses. Clears faster without DAC, so it's usually paired with another GH peptide for stronger effect.
GHRP-2
Stronger GH release than GHRP-6, with more moderate appetite increase. Raises both GH and IGF-1, though it can slightly bump cortisol and prolactin.
