Side-by-Side Comparison

AspectCJC-1295LL-37 (Cathelicidin)
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.Disrupts bacterial membranes, neutralizes endotoxins, modulates immune cell function, and promotes wound healing. Has both direct antimicrobial and immunomodulatory effects.
Typical DosageCJC-1295 DAC: 1-2mg weekly. CJC-1295 no DAC (Mod GRF 1-29): 100-300mcg 2-3 times daily.Research protocols vary widely. Typical ranges: 50-200mcg administered subcutaneously 2-3 times weekly. Some protocols use higher doses for acute infections.
AdministrationSubcutaneous injection, often combined with a GHRP like Ipamorelin for synergistic effects. Best administered before sleep or fasted.Subcutaneous injection. Can cause significant injection site reactions. Often used in conjunction with other immune-supporting protocols.
Side EffectsWater retention, tingling in extremities, potential increase in cortisol and prolactin levels.Injection site pain and reactions are common. May cause flu-like symptoms, temporary fatigue, or immune activation responses.
