I've been using sust for 4 weeks at 1cc and achieved awesome results but noticed my energy and intensity is not as high like it was on my 3rd week so I started doing 1.5cc of sust which gave me a little better intensity, but not as high.
Side note: I realized more food helped me with the energy, but i'm still wondering about the intensity.
