I would personally recommend CJC -1295 without DAC (30 minute bioavailability) to CJC-1295 with DAC (7-10 day bioavailability). GH is released by the body in a pulsatile form. This means you have frequent spikes and troughs. The body is supposed to do this. With sustained GRF (CJC-1295 with DAC), the result is a slow GH bleed that produces less GH than the pulsatile model. This is a more feminized pattern of GH relsease, and not recommended for mass building/recomp purposes, not even for anti-aging.
Pinning TID (3x/day) may not be fun, but it's still your best choice.
The observation was made that the difference between peptides and GH is like night and day, and I agree (from a pharmacodynamics perspective). Once again, daily injections of GH produces more of the "continual bleed" than pulsatile release, but not as badly as CJC-1295 w/ DAC.
While I've never been lucky enough to try hgh (no source; and NO, I'm not asking for one), from the literature and forums it seems GH has a much stronger bulking effect, whereas peptides are more for body recomp. GH also carries the risks of organomegaly, acromegaly, and tumor hypertrophy (it is not tissue-specific). From what I've read, these perils are avoided with peptides (CJC, GHRP, Ipamorelin, etc.). Don't take my word for it though; search the literature.
Hope this helps.
