Here is a very simplified explanation:
You will have to elaborate on what your doses of eq and deca were, but I can tell you that with 15 day halflives - give or take, combined with the accumulation of these drugs throughout your cycle, that it is not unreasonable to estimate that you will still have supraphysiological levels of AAS in your body up to and beyond the six week mark. I am sorry to say but you have a accumulation of AAS which means exponential sums of each injected dose need time to clear your body.
As long as levels remain supraphysiological, you can take all the clomid, nolvadex, eurocoma or whatever. it won't help you recover, because you are actually still 'on'.
HCG is another big bad brute that many including myself have paid the price by using. Hcg is an analog of LH which is secreted by your pituitary gland in response to stimulation from your hypothalmus where receptors sense the need to produce more testosterone. The hormone binds with receptors of your leydig cells in your testes. This stimulates production of testosterone and maturation of sperm.
The problem with hcg use is that it is very easy to 'burn out' the leydig receptors - causing them to become 'desensitized' to normal LH production from your pituitary gland.
Hcg has such a small halflife that doses must be incredibly small not to cause damage. Unfortunately most people just inject 3000 iu's at a time, when 30 ius would be much safer. This makes administration impracticle however because of the short half life, it would have to be injected frequently - such as every few hours.
So if you use HCG you will be creating suppression on two levels: - first your htpa, and secondly your leydig cells.
This further complicates you problems.
Many people ask the question, so if this is the case, why dose my vial have 10,000, or 5,000 iu in it?
well plain and simple, hcg is used mostly for veteranarian use, and by fertility clinics. The goal is to increase production of sperm, testicular health in the aftermath is not a concern, as the end justifies the means, and the goal is conception, not testicular health, or pct.
so is there a alternative?
why yes there is, instead of hcg, while on cycle continue to use TRIBEX. This may keep the testes from completely shrinking. In addition to this at cycle's end using a taper with testosterone, will keep your test levels high enough to support your libido, but as you drop the exogenous dose slowly, provided of course you have been using aromatase inhibitors throughout the cycle (preferably) and there is not a whole wack of estrogen accumulated and sitting up in the ol' htpa waiting for their turn to bind to the ER - as you decrease the exogenous dose slowly, your endogenous production should pick up the slack. This will give your testes time to grow back to size, and you will only still have one level of suppression to deal with, not two.
granted this approach is best suited for long cycles, as shorties tend to be better quit cold turkey.
The final word is that all pct must only be initialted after the steroid has sufficiently cleared enough.
I see too many BB's on these boards planing their pct to begin the day after their last shot of enanthate. I will say it now - don't bother for a full month! you are just wasting your effort, and your money.
