47 years old and recently started trt.. I’ve been reading around the internet and seems like, people are adding different steroids to their trt. I’m currently on 200 mg a week of testosterone. I’m looking to get some help when it comes to my joints and my back pain. Wanted to know if it was okay to add some Deca and how much would you recommend, should I start at maybe 150 mg a week and then adjust it from there?
