This is pcushion about as natural as he comes. This is 100mg test cyp/ wk and primo 400mg/wk. I utilize primo during my cruise bc it allows me to keep 100% of cycle gains and pushes more gain than trt alone. Keep in mind this my my method and what works for me. I also fully understand the possible consequences of my actions and am fully prepared to accept them. That said before you decide to try cycle on or blast and cruise make sure you fully educate yourself. Happy Pinning Guys and stay safe.
