CJC-1295 (no DAC)

Also known as: Modified GRF 1-29 · Mod GRF (1-29) · CJC-1295 without DAC

What it is

A synthetic analog of the first 29 amino acids of growth hormone-releasing hormone (GHRH), without the drug affinity complex (DAC). Supplied as a lyophilized powder.

How it works

Binds the GHRH receptor on pituitary somatotrophs, stimulating short pulses of growth hormone release. Lacks the DAC modification that extends half-life.

Where it's used

Studied in research settings as a short-acting GHRH analog.

Regulatory status

Not FDA-approved; research compound.

Reconstitution

Supplied as a lyophilized powder requiring reconstitution with bacteriostatic water prior to use.

Do the math once, not every pin. The reconstitution calculator converts vial mg + bacteriostatic water into exact syringe units for any target dose.

Tracking it

CJC-1295 is injectable, so two things matter in a log: when you dosed and where. Rotating sites and writing both down prevents the classic “did I already pin the left side?” problem. with a half-life of about 30 minutes, a dose log also lets a tracker model the relative amount still in your system between doses.
