You can try it out but understand that even though one is on trt and if your testosterone levels are in a healthy physiological range whether mid-normal or high-normal depending on your protocol and how you as an individual respond to testosterone.
Even though one will see improvement in body compostion (gaining muscle/strength, loss of body fat) and will notice improved recovery when lifting weights it is not the same as using steroid doses to attain testosterone levels well into the supra-physiological range where one would notice much greater gains in muscle/strength and greater recovery abilities.
The 3 main factors which contribute to recovery are anabolic hormone levels/rest(quality sleep)/nutrition.
Even if one has healthy testosterone levels, lacking the proper nutrition/rest, recovery abilities will be impeded.
Training too intensely, long or often will also negatively effect recovery.
Soreness is a descent indicator but it is the nervous system not just the muscle tissue that takes a beating from heavy intense training sessions!
Hi jatindell, From your experience over the course of the 16 years, what is your go-to routine?
Either way, in regard to the point about training body parts more than once per week, it could definitely be a great option. The train-one-muscle-group-once-per-week concept is effective for newbies (with higher propensity to respond to the training stimulus) and steroid users. It's in many of the training programs you'd see in the fitness mags/resources, and is frankly misleading. Full-body and/or compound movements done multiple times per week is really the way to go. Even though you're on T, it's not at the supraphysiological levels of steroid users, so blasting one muscle group once per week wouldn't necessarily help you. For natural lifters, fewer sets per day (but spread out across 2 or 3 times per week) could be beneficial.
Though my routine evolves every couple months, I like training and see results when doing only one or two exercises per muscle group per day.
