first i want to make clear the whole 3inch gain on ur arm in 30 days they claim is a load of shit and very deceiving
basically injecting the stuff causes alot of swelling and can make u think uve gained so much size
1-MAYBE 2 inches is wat u can achieve, some guys even make no gains after there run, why i dotn know
the pain and all the injections is also very hard to do everyday
as for maintaince, i beleive u can maintain synthol gains IF you stay on gear for life, if your someone who goes on and off i feel pretty confident in saying ull loose wateva gains u make pretty fast or eventually
but then again synthol IMO isnt for an ametuer or casual steroid user, it really is something IMO u should only use if you really are that serious about bodybuilding, or have a stubborn bodypart that doesnt grow even on a gram of gear or in portion with ur body
ive been able to maintain my gains, but then again i dont come off gear so it be expected id maintain them, if i came off gear however i feel id loose my gains just liek i would for every body part
