Tren is garbage IMO. Sure it'll make you strong, but it'll probably put weight on you bro. The weird pissiness that comes with it, the shitty sleep, the fatigue, the odd thoughts and progestin sides.
It doesn't hold a candle to Halotestin. Run 30mg/day 3-4 weeks out from your competition, it'll blow tren out of the water. You wont gain any weight on it, or bloat, or anything weird. It's a good predictable drug that will help you stay extra motivated/aggressive during low calorie cutting phases. It fits the bill better than anything really...
Have you run primo before? The injections suck big time. I've never complained about putting 6ml's into one site, but primo is like getting shot by a goddamn gun. At 750mg/week I loved it though (along with mast e, test e).
Good luck buddy
