I just found out that my 20 year old little brother started doing juice.. i bitched him out for a good half hour. He promised me he will stop, he told me he was doing test..i belive for around 7 weeks now...so he's almost done his cycle. is their any problems that will occur to him...like will he be able to still build muscle after he comes off normally? like will his receptors be ****ed for good?
