I would like to state that I have used hCG in all three of my cycles (stats and info can be found in my profile), usually starting sometime in the middle/beginning of the cycle and running it at 250-300IU E3.5D. All of my cycles have also included some form of testosterone, ranging from 500mg/week - 600mg/week, for no longer that 10 weeks as of now.
Many people don't actually know what hCG does or how it works.. When exogenous AAS are put into the body, natural negative-feedback loops cause the body to shut down its own production of testosterone via shutdown of the hypothalamic-pituitary-gonadal axis (HPGA). This causes testicular atrophy, among other things.. hCG is commonly used during and after steroid cycles to maintain and restore testicular size as well as normal testosterone production. In males, hCG helps restore and maintain testosterone production in the testes by mimicking LH and triggering the production and release of testosterone. In theory, your natural testosterone production could never be surpressed, even with the use of powerful or high doses of AAS (for a limited time, of course).
I have seen various threads that pose the question "could I just take Deca at 400mg/week for 12 weeks with HCG at 250IU E3.5D for 15 weeks along side of it?" Most vets and mods will will strongly recommend against this, but I really don't understand why.
If your natural testosterone production is intact, and can remained intact for the 12-14 weeks AAS are active, with the use of hCG, why can't a cycle like this be done safely with no suppression of testosterone levels?
Is there some scientific explaination that I'm not finding?
Or is it just that when high levels of potent AAS are used, your natural testosterone production is not enough and will still get suppressed? Is the any evidence/personal experience from members to support this?
