depends on your goals, wat level in training your at etc
i personly use tren as part of my blast and cruise protocol, using 80mg of tren e a week during my cruise the stuff helps me maintain abs all year round with a much lazier diet, and of course keep my physique looking hard
low doses of tren in my opinion are awesome, you get to experience some of the magic without many of the serious sides guys complain about
in my opinion of your looking for something nice, but without the sides, id go for 200mg a week, no more, ull love the stuff
