I actually have a couple questions about dieting, var, clen and stacking? any answers will be greatly appreciated.

I have a cycle of var, i want to take 25mgs is that an okay amount? My first cycle was 15mg i saw gains and felt fine. I was on 10 weeks on and will be ten weeks off. Now can i stack that with anything to increase my outcome to achieve the successful results i want? I also have clen but not sure about taking it i havnt done my homework on it as much.

I am entering the fire academy in 6 months, i train 5 days a week, and have a very strict diet. my goal is to cut the fat, gain strength.

Im new at this so please be patient lol thanks
