I have been using Hcgenerate for about 10 days now. It is my first time trying it. I started it immediately after a 30 day run of DAA plus Endosurge. That combo seemed to give me a bit of a strength boost, but when I switched over to Hcgenerate, my libido has gone through the roof. Much better than the DAA/Endosurge combo in terms of sexual effects. Gains in the gym continue. Feels good.
