two things that can both greatly increase water retention. i know for me, as someone who has used creatine in the past, it can be a helpful tool, but i discontinued it due to water retention issues. now as someone who is using trt, i greatly switched to cardio over weights because i have to battle water retention on testosterone injections and hcg. i can imagine if i used them together, i would get incredibly strong but also feel incredibly inflated with water. for myself, its an uncomfortable feeling and i get anxiety, probably from increased blood pressure due to water retention.
some guys like being massive and bulky, not for me but im guessing the two would work well if that was your goal.
