I have read in a few palces that clen sides are only temporary and there are are NO long term effects. So basically if you get off your cycle with no problems your in the clear. Recently i read an article saying it can enlarge your heart, and have other LONG TERM EFFECTS. I am sometimes weary listening to how safe steroids are on a site like this because so many people use n decide to ignore the sides, n make themselves beloeve its 100 percent safe, which just isnt the case, i agree they are not as bad ad people make them out to be, but their also not as safe as many users make them out to be. Ne way without rambling on nemore, is clen a safe drug to take, does it ahve ne possible long term effects i should know about, and waht is the safest way to use, 2 on 2 off, or 6-8 on using benadryl?
