Clen will build up your tollerence to stims. Take a 4 week break every 1 to 2 months and you should never have that prob again. Try 40 mg and see how that gose. Craze is a great 1.3 free product. Best stim product I have ever had. 6 scoops of jack3d is about 120 or so mg of the 1.3. Thats danger zone dose and expensive. Craze is a one scooper for me and I am at a very high stim tollerence rite now. Cost effective as hell! And no there is no meth in it....*rumor*Originally Posted by Manu_el_
On your breaks from stims you can give it a go with no pre workout or you can try pump products. Hemavol is by far the best *my opinion.*
As for the cortisol thing you can reduce it naturally by spending more time resting. 4 xa week max for weights unless your on the juice. Or you might be overtrained which means take a vacation
As for the clen thing how long have you been taking it?
