    Testosterone production is governed by the HPTA and if you administrate exogenous testosterone you will eventually shut down your natural production via the feed back loop. HCG will mimic LH which will results in direct stimulation of the testes which will results in increases in testicular size and sperm production, HCG or even PCT compounds like nolva/clomid will not start natural testosterone production again because there is exogenous amounts testosterone being administrated and these compounds will not over ride the negative feed back loop. Only and when there isnt an abundance of testosterone will stimulation and regeneration of the HPTA can occur.

    End of discussion.

    I actually had this debate with DC over at PM.com a few weeks back but his logic was flawed.
