About CJC-1295 DAC
CJC-1295 DAC is a GHRH analog carrying a Drug Affinity Complex (DAC) modification that binds covalently to circulating albumin, greatly extending its plasma half-life relative to unmodified or short-acting GHRH analogs. Through this albumin binding it acts as a long-lasting agonist at pituitary GHRH receptors, associated in research with sustained growth hormone and downstream IGF-1 elevation. This contrasts with the non-DAC form (Mod GRF 1-29), whose action is measured in minutes rather than days.
About Follistatin 344
Binds and neutralizes myostatin (GDF-8) and activin; removes the natural brake on muscle growth allowing supraphysiological hypertrophy

CJC-1295 DAC
Class-based (investigational)
Research protocols routinely measure IGF-1 to track GH axis activity before and during use. Fasting glucose and insulin are monitored because GH elevation can reduce insulin sensitivity over time.
global — WADA
This compound falls under WADA Prohibited List category S2 (Peptide Hormones, Growth Factors, Related Substances and Mimetics), prohibited at all times for competing athletes.
