I did 200 mg/week test cyp along with 25 mg/day trest ace when I first found out about trest in 2016. It transformed my body faster than anything else I had tried. I gained a lot of weight (some muscle along with water), I felt amazing, I had endless energy in the gym, and I had the libido of a teenager again in my 40s. Trest became my favorite steroid at that point.
I've done lots of cycles with it since. I use 15 to 25 mg/day on blasts and stay on 10 mg/day along with low dose test on cruises. I don't plan on coming off anytime soon.
