Your trt doctor will run bloodwork and look for your estrogen and testosterone levels mainly than also lh and fsh plus free testosterone.
You can take alot of compounds that won’t effect these numbers any different than trt already would. You can run a trt dose of testosterone and run primo,masteron, and so many more compounds. Just watch your cholesterol with orals and estrogen with other compounds and as long as your testosterone levels stay within range your good.
You have another way also of doing a blast and cruise scenario were you blast 8wks a cycle stack and then go back to just your trt dose until you pass your next blood test and then blast again and again. Alot of people argue that 8wks is the perfect cycle time for optimal gains from the compounds. Especially short or shorter esters.
I believe that the second scenario is what im going to be doing moving forward. Just a trt dose of 200mg/ml test cyp and I will add other compounds and adjust my diet for my goals.
