Tweetcyp is a long ester so weekly or bi weekly injects would be fine. as for dose i have only used transdermal but i would keep it between 300-400mg and use an anti E like nolva or liquidex because it redily aromatizes to estrogen. stack it with some 1 test and you will have a good cycle. i would run it 10 weeks or longer. dont forget proper PCT 2 weeks after your last shot.
