Good/legit CLEN? help!

I'm 18 years old, and i've been working out for 4-5 years. I'm a aspiring fitness model/bodybuilder, and I was looking into finally cutting down. I'm 5'10,202lbs, 15% body fat. I ordered some CLEN from Precision Peptibes, does anybody know if there CLEN is legit? Also what would be the best cylce to follow to cut? Thanks

forget the clen and adjust your diet.
if you want to be a model your diet is going to be the most important factor.
