Tweeti wouldn't start with 2. i'm sure stone would love to able to go higher cause he would get better results, his body just won't let him. i would plan on 3-4 and just lower it if it gets bad. i used 4 with serono but 3.3 with jin but it wasn't for long with jin. i'll have a better feel for the jin after i complete my next cycle. but i hopen to like jin alot better cause i noticed fat loss in just 6 weeks with it.
