Yes, while on cycle, HCG will keep your body producing and it will also keep the testicles from shrinking. Reduced teste size will limit how much test your body will produce. So keeping them full will help with recovery. Maintaining them is easier than trying to bring them back. So 250iu to 500iu, 2x wk through the cycle. Then if you have more, I would increase the dose to 1000iu every 3 days for a wk or 2 leading up to PCT. Most important, no matter how you choose to use it, come off of HCG before you start PCT or you won't give your body a chance to produce on it's own.
