GHRP-2
Also known as: Growth Hormone Releasing Peptide-2 · Pralmorelin
A second-generation GHRP with high GH-releasing potency and a cleaner side effect profile than GHRP-6. Less appetite stimulation makes it preferable for body recomposition.
What is GHRP-2? A second-generation GHRP with high GH-releasing potency and a cleaner side effect profile than GHRP-6. Less appetite stimulation makes it preferable for body recomposition.
How does GHRP-2 work? GHRP-2 is a synthetic hexapeptide that acts as a potent GHS-R agonist. It stimulates pulsatile GH release through both pituitary and hypothalamic mechanisms with less pronounced appetite stimulation than GHRP-6.
Benefits of GHRP-2: Strong GH release with less cortisol elevation than GHRP-6; Muscle growth and recomposition; Fat loss; Minimal appetite stimulation; Improved recovery; IGF-1 increase
GHRP-2 dosage: Better choice than GHRP-6 when appetite stimulation is unwanted.
GHRP-2 half-life: 15-60 minutes

Ibutamoren
A non-peptide, orally active growth hormone secretagogue that mimics ghrelin, significantly elevating GH and IGF-1 levels. Unique in being orally bioavailable.
CJC-1295 No DAC (Mod GRF 1-29)
Modified GRF 1-29
A synthetic 29-amino acid GHRH analog with 4 amino acid substitutions that improve stability and receptor affinity compared to Sermorelin. Unlike CJC-1295 DAC, it has no Drug Affinity Complex, giving it a short 30-minute half-life that mimics the body's natural pulsatile GHRH secretion when co-administered with a GHRP.
Follistatin-344
FST-344
A naturally occurring protein that inhibits myostatin and activin, effectively removing the biological ceiling on muscle growth.
MGF (Mechano Growth Factor)
Mechano Growth Factor
A splice variant of IGF-1 released in muscle fibers in response to mechanical damage. Activates muscle satellite cells to initiate repair and hypertrophy.
