@Mathb33 no idea what your coaching costs, but if you are satisfied with it and can discuss that could be helpful.
A lot of big name coaches, from Dante Trudel to Matt Jansen (for his regular clients) have basically just said off-season growth is generally push as much test as the individual comfortably handles, then maybe one other compound at a small dosage and that’s it.
Say a guy gets on with 500-800 test and then adds 100-200 deca. Tons of clean food, 1-4 iu of HGH, and hard heavy training take care of the rest. Vigorous Steve (he does take clients) likes test and some primo basically and he is very health conscious. He’s also in Thailand so he may be cheaper.
The show is when calories come down and gear goes up and aggressive compounds come in, but never off-season. Some coaches do some Dbol or Anadrol in off-season but that’s going to be individual and I’d worry about how they affect bloods when making that call.
