Evidence at a glance

Human and animal counts are PubMed records from our evidence ledger (search counts, not studies we reviewed). The grade is the strongest design among the studies we summarised for that goal: a human randomized trial outweighs any number of animal studies.

Common questions

Is CJC-1295 FDA approved?

CJC-1295 is Not FDA approved · research chemical. Products sold as research chemicals are not the approved drug and are not checked by the FDA.

Is CJC-1295 banned in sport?

Yes. Prohibited by WADA (S2.2.4), so it is prohibited at all times for tested athletes.

How much water goes in a 10 mg vial?

That choice only changes the concentration. With 2 mL, the vial is 5 mg/mL. The calculator converts any amount to syringe units. It does the math only and does not suggest a dose.
