Not directly, but the real value is more in the recovery and sleep side of things. Even actual HGH is only mildly anabolic at best, so don't expect it to drive massive gains on its own.

Honestly sema wasn't even close for me — bad side effects and I actually ended up gaining weight on it. Reta has been a completely different story, I'm down 48lbs and have managed to hold onto most of my muscle mass. No contest in my book.

Big peptide fan here, but I'll be real with you — CJC-1295 and GHRP-6 are just nudging your natural GH levels up a notch. You'll probably notice improved sleep and recovery, but don't expect them to be building muscle directly — whatever gains you see are really just a byproduct of recovering better and being able to push harder in the gym.
