Subtle effects, expensive 2026-05-27
Hannah V.

Used CJC-1295 for 8 weeks. Sleep improved but the body composition changes were subtle. Better stacked with a GHRP. The DAC version lasts longer but water retention can be an issue.

Better sleep and recovery 2026-05-07
Hannah V.

CJC-1295 with DAC improved my sleep quality significantly. Deeper sleep, better recovery. Noticeable body composition changes over 3 months - leaner while maintaining muscle. IGF-1 increase is real.
