CJC-1295 (with or without DAC) increases natural growth hormone production. Standard dosing: 1-2mg per week, split into 2-3 injections. Almost always stacked with Ipamorelin or other GHRP for synergistic GH pulse.
This calculator shows weekly dose, injection timing (2-3x weekly), injection volume based on concentration, and total vials needed for your protocol.
CJC-1295 dosing approaches:
CJC-1295 without DAC (Mod GRF 1-29):
Dose: 100-200mcg per injection
Frequency: 2-3x daily with meals or before bed
Works synergistically with Ipamorelin/GHRP
Short half-life, requires frequent dosing
CJC-1295 with DAC:
Dose: 1-2mg per week total
Frequency: 2-3 injections weekly (or single weekly)
Long-acting, elevated GH for days
More convenient than without DAC
Example: 5mg vial + 2ml water = 2,500mcg/ml
1mg dose (1,000mcg) = draw 0.40ml
100mcg dose (without DAC) = draw 0.04ml
Most people use CJC-1295 WITH DAC for convenience.
