I use HCG in combo with TRT therapy to keep my balls working... the rule is never use more than 500 ius per shot... Your testes will respond to this and smaller amounts...higher amounts are too strong and will possibly cause desensitization to the leydig cells, plus cause more estrogen. New medical practices with HCG generally recomend LESS IS MORE!
The best way to use HCG, boys, is to use it through your whole cycle in small amounts of 250 ius once or twice a week... this will stop your gonads from shrinking and they will continue to produce T during the whole cycle....
Reconsitute it as directed and inject it subcuteanously in the abdomen with a small insulin needle... it does not have to be injected intramuscularaly. It must be kept refrigerated.
