You don’t want to use HCG - human chorionic gonadotropin - after the cycle if you ran it during the cycle.
The point is to keep your testes functioning during your cycle. When you take anavar this will shut off your lh - leutenizing hormone - so your testes will have nothing stimulating them if you dont take hCG. If they are inactive for long enough (4 or more weeks) they become desensitized to the effect of LH, so even after you quite the steroids and your LH levels return to normal your testes will no longer produce the same amount of testosterone they once did. This is why its so important to keep them active with an LH mimicker like hCG.
Your LH will return to normal fairly quickly after a cycle so you won’t need the hCG any longer… and if you continue to take it, it will suppress your body’s own LH and will only prolong recovery.
IMO, hCG on cycle is necessary for any cycle over 6 weeks.
