I’m 33 years old, 6’7″ tall and weigh 200lbs with approx. 17% body fat. My base weight never changes unless I work out. Slender build, so historically I show gains quickly. However, lately I am not getting the results I want. I just started working out again, 3-4 times per week, after not working out at all for 2 years off. After 3 months, Im definitely not happy with the results. In the past, I would have put on 20lbs of muscle mass by now. Im eating healthy and all, but my gains just arent what I expected or want. What would you recommend for an extra boost to put on muscle mass? I want to build massive arms, chest and legs. I hit a speed bag and do sit ups in addition to the strength training, so that helps with definition. I’m not really worried about getting cut because that (historically) happens on its own due to my physique and training routine. I definitely don’t need to lose any weight. I just want to gain mass and strength. To be honest I really want to build massive arms and chest above all. I’m on a budget, so if you could offer advice for the ideal product stack, as well as a less expensive option (to get me started) I would greatly appreciate it.
