So nolva doesnt restore Hpta.... Wow are you a scientist?
I think most people that have even the slightest idea what they are doing would know this, that is why we use hcg, and it's not always needed.
After any cycle a SERM should be used, either clomid or nolva.
SERMS help to "kickstart" a sleepy hpyothalmic GnRH response.
GnRH is pretty quick to recover but SERMS help the hypothalamus to "turn the key" on the GnRH impulse generating engine.
SERMS block the affect of estrogen at the hypothalamus and since estrogen is highly inhibitory this blocking affect allows for greater LH production.
This "greater LH production" strongly stimulates the testes to produce testosterone.
If you use only gear that does NOT aromatize to estrogen then you don't have to worry about the inhibitory affect of estrogen post cycle(from the steroid)...but SERMs should still be used to counter the inhibitory affect of the estrogen seen form the T production(from the hcg use).....and also from the estrogen production from the aromatization of the T production form your testes after the hcg is stopped.
*Even if you never used HCG you should still use a SERM after a cycle with non aromatizing gear to counter the inhibitory effect of normal estrogen production(from the aromatization of T from your improving T production)
You have to wait until exogenous androgen levels drop to a similar level of what a normal T production would be, in order for this LH stimulating affect from SERMS to work, since androgens are also highly inhibitory on the hypothalamus.
If your trying to sell a product, well good for you, but to put peoples hard earned gains at risk just to make some $$ makes me feel sick.
