I would run your HCG during the cycle. However much you have, I would time it out to run about 250-500iu, 2x wk, up to about 3 days before PCT. This way you keep teste size and force natural test production. Then when you it your PCT, you are already "primed" and ready to go. I am a big believer in using HCG with Deca. Deca is one of the hardest drugs to recover from. Having the HCG and then running a good PCT of clomid after the cycle will allow you optimal recovery
