the only reason why clen is important is because its a very strong anti-catabolic. which is good after a cycle since your natural levels of test are down. it will also help burn that extra fat. but its not a must so you can just do clomid and nolva. keep eating alot and have glutamine in had (most whey products already have it) this is also an anti-catabolic so it real good.
good luck bro
