I have to agree that using smaller doses during cycle is the ay to go.
I can notice almost an immediat effect at only 500 daily for 5 day runs.
I think all the pros are on HGC all the time, but what do they know. They are only doing more gear in a day then I do in a week.
I happen to believe that it would take mega doses over long periods of time to have a real negative impact on LH sensitivity. I really think that the idea of HCG causing down regulation of some sort in the puituitary or hypothalamus is over stated.
Remember this, HCG is just a replacement hormone, it does not really "kick start" natural production as mentioned above. As a matter of fact, a big dose of HCG will have your testes pumping out MORE than normal test levels which can actually cause gyno!!
I would be carefull of this if you start HCG right at the start of a cycle...I would say take it after the first 2-3 weeks and NO SOONER ! Everyone should experiment with it a bit to see how their body reacts to it. If you can get away with lower doses, then do so!
