I've been using ipa and grf 1-29 with good results in terms of deeper sleep, recovery, and fat loss. But, when I ran out, I went with separate CJC 1295 w/DAC and Ipa and it's been much better. I know many people say to not use DAC because it doesn't mimic natural pulse of GH, but I don't have the time to inject multiple times a day and feel the sustained release of CJC 1295 is making this more effective.
