CJC-1295 (without DAC) Dosage Guide, Benefits & Side Effects

The lyophilized (freeze-dried) powder is generally recommended to be stored frozen or refrigerated before reconstitution, protected from light. It is typically reconstituted with bacteriostatic water, and once mixed, is commonly stored refrigerated and reported to remain stable for roughly 2–4 weeks, though potency can gradually decline over time. A frequently cited practical setup is a 10 mg vial mixed with 3 mL of bacteriostatic water, yielding about 3,333 mcg/mL, so that 100 mcg equals about 3 units and 300 mcg equals about 9 units on a standard U-100 insulin syringe. Exact stability windows vary by source and are not independently standardized.

In the United States, CJC-1295 without DAC is not FDA-approved for human use. It is widely sold by suppliers labeled strictly for laboratory research purposes, not for human consumption, veterinary use, or clinical application. Purchasing and possessing it for genuine research through such suppliers is generally treated as legal, but using it for personal/human administration falls into a regulatory gray area and may carry legal risk depending on jurisdiction and how it is obtained or administered (e.g., through a licensed prescriber and compounding pharmacy versus an unregulated research-chemical vendor). It is also banned in competitive sport, listed under WADA's S2 category of prohibited peptide hormones and growth factors.

Its short plasma half-life (approximately 30 minutes) means blood levels drop quickly after each injection, so a single dose only produces one brief pulse of GHRH receptor stimulation. To generate multiple GH pulses across the day — which is intended to more closely resemble the body's natural GH secretion rhythm — it is typically injected multiple times daily (e.g., morning, around exercise, and before sleep). The DAC-modified version, by contrast, binds to serum albumin and stays in circulation for days, allowing far less frequent (often weekly) dosing but producing a more constant, non-pulsatile elevation instead.

A commonly cited timing approach is to inject in a fasted state — at least 1–2 hours after eating and preferably with elevated blood sugar avoided — since insulin and food intake can dampen GHRH-stimulated GH release. Popular timing windows discussed in vendor and community sources include first thing in the morning, immediately post-workout, and roughly 30 minutes before bed, the last of which is intended to amplify the natural nocturnal GH surge that occurs during early deep sleep. These are practices reported in non-clinical sources rather than an established medical protocol.
