Lads, did a 3 week cycle this past September, gained 16pounds-happy as hell, but the low side was the back aches, and the loss of libido, felt vert tierd also. Coffee helps, ate like a horse, all clean foods. Gonna do my next 3 week cycle in Feb, my question is do I need to a 3 week cydclle as i gained next to nothing in the third week.
