CJC-1295 vs FGL

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

CJC-1295

CJC-1295 is a synthetic analog of growth hormone-releasing hormone (GHRH) that stimulates the pituitary gland to produce more growth hormone.

Side-by-Side Comparison

AspectCJC-1295FGL
MechanismCJC-1295 binds to GHRH receptors in the pituitary, triggering increased production and release of growth hormone. The DAC (Drug Affinity Complex) version extends half-life significantly.Binds to FGFR1 (fibroblast growth factor receptor 1) to activate downstream signaling cascades that promote neurite outgrowth, synaptic plasticity, and neuronal survival.
Typical DosageCJC-1295 DAC: 1-2mg weekly. CJC-1295 no DAC (Mod GRF 1-29): 100-300mcg 2-3 times daily.Research protocols have used subcutaneous doses ranging from 1-10mg. Intranasal administration also studied. Optimal dosing not established.
AdministrationSubcutaneous injection, often combined with a GHRP like Ipamorelin for synergistic effects. Best administered before sleep or fasted.Subcutaneous injection or intranasal administration. Research compound with limited human dosing data.
Side EffectsWater retention, tingling in extremities, potential increase in cortisol and prolactin levels.Limited human data available. Animal studies show good tolerability.
