I always get conflicting opinions on this and would like your feedback pleaseee:
What is the MOST effective way of using HCG to AVOID testicular atrophy and to preserve my natural Test for the FASTEST recovery from a cycle of 600mg Prop and 400mg NPP?
Most effective is going be slightly different from person to person and be dependent on how they respond to HCG as well as the cycle they are on. Typically a couple small bumpbs of HCG weekly (ie 250IU or so) are enough to keep atrophy to a minimum but it will do little for natural test production. You generally need a bit bigger dose of around 700units to cause a bit of natural test to be released but this is likely going to be affected by how heavy your cycle is.
As I stated above its hard to say, no one can give you the "best way" because its different all the time.
I would probably just start with 250 units a couple times a week. if you start to notice atrophy bump it by 100 units for that week and see if it has any impact, if so hold steady and if not bump 100 units again until you find the dose that keeps your testis from shrinking too much.
I'm on HRT and don't really notice much atrophy. I do a couple of 500 iu hits twice a month. Can't say I notice much of a difference but I think it's good to release some of your own T now and then.
