Nah you'll feel really depressed and have no energy and your joints will ache like fuck. Took too much Adex once, can't imagine what taking letro would feel like for a natty.
yeah im like 220 at 12-14% most of the year, never get fat enough that I have no resemblance of abs. Assuming your cardiovascular system is in good health I wouldn't describe taking clen as messing up your body. You can get clen prescribed for asthma in some countries. What is in inhalers salbutamol is very similar to clen, but it won't make you shake. If your thinking of taking clen i'd just go on all day chemist and buy a few packs of salbutamol tablets or if they dont have them the inhalers, feels much better then clen.
