The ES version really focuses towards libido enhancement... It has an extreme amount of libdio aides and really shines in this way... it also contains several added ingredients for extra test boosting, mood enhancement, better sleep and enhanced recovery... it can be used in any scenario whether during pct, a pct kickstart, on cycle or as a stand alone... the two most common uses for the ES version are as a sarms mini pct or as a kickstart to a steroid cycle pct... it has been utilized by many as regular HCG would with a blast before pct except hcgenerate is not only used in the two weeks prior to pct but also into and possibly throughout an entire pct as well... it can be ran up to 12 weeks so if a user wants to run it not only as a kickstart to pct but all the way throughout, it is perfectly fine and highly recommended... the regular version of hcgenerate is specifically designed to keep on cycle suppression to a minimum, making your transition into pct much smoother, allowing for an optimal recovery and more keepable gains… It also prevents testicular shrinkage and your libido strong on cycle...
