Hcg is used to combat testicular atrophy that usually occurs when moderate or higher doses or aas are used, although honestly most people experience at least some testicular atrophy even with mild doses.
You can run Human Chorionic Gonadotropin (HCG) as part of your cycle and as post cycle therapy (pct), i would recommend both. Run the Human Chorionic Gonadotropin (HCG) 250iu's twice a week for the duration of your cycle. Some people recommend starting it a couple weeks in, which is usually when testicular atrophy begins, but why fix a problem when you can prevent it from happening in the first place, 250ius twice a week will not cause desensitization of the testes. When you finish your cycle Human Chorionic Gonadotropin (HCG) can be used in a blast-type fashion where you will pin 500-1000iu's eod, its important to do it eod so as to get a pulse pattern going(which the testes respond better to), for ten days. Wait a few days for the Human Chorionic Gonadotropin (HCG) to clear and then you begin pct.
Hcg is injected sub-q with an insulin pin, so you will be injecting into your fat, i've always injected into my stomach.
