i hear people using clen in pct.. i think its the worst idea i have ever heard...
OP, if you are going to run clen run it 4 weeks on 2 weeks off.. every other week youre going to want to run 1mg keto ed to keep the beta receptors fresh..
clen, like anything else that depends on beta receptors, will cause a quick tolerance to itself in the human body
start with 40mcg a day and move up 20mcg a day until you feel just slightly jittery.. thats the correct dosage to start at..
good luck!
