In terms of muscle building the top options seem to be TRT combined with HGH and Reta although they do come with risks and proper amounts are important to figure out. This approach doesn't suit everybody.
I've always liked Tesa a lot. Right now I'm on it and figure it will continue as a regular part of what I do. My preference leans toward viewing it as better than CJC-1295. However, I also wouldn't rush to ignore CJC either. Tesa got looked at specifically for cutting down on internal fat in HIV patients who had lipodystrophy. On average, they carried higher amounts of that fat than most people wanting to improve how their body looks. We haven't had the same kind of research with CJC-1295, so comparing them directly may not be fair. This holds more when it's used together with Ipa. I wouldn't find it shocking if results end up quite similar over time, depending on things like the person, what they eat, how they train, sticking to the schedule, and where they start with body fat levels.
