Use an AI if you havent used one when "on" to lower estrogen, which is extremely suppressive (leydig cells) during PCT.
Use proven SERMs (Clomid, Nolva).
Use Tormifene, which is one of the best available SERMs for restarting a shutdown HPTA. Its also a 2nd GEN SERM and has less occular toxicity and geno-toxicity than both Tamox/Clomid and is VERY effective at raising endogenous T in studies as recent at Apr/2009.
Use HCG when "on" to maintain testicular size/function.
My advice is:
Steroid/ProHormone cycle causing HPTA shutdown (HCG may not be needed in cycles below 6 weeks IMHO)
Use HCG 125-250ius 2-3 times weekly. This will maintain testicular function by maintaining endogenous testosterone prodction and ITT (Intra-Testicular Testosterone). Using HCG throughout is the best protocol available IMHO. This is confirmed by Endocrinologists I have had contact with. It will also prevent the onset of testicular dysfunction by directly stimulating the testes.
After this peroid we then use PCT to restart GnRH from the hypothalamus and LH/FSH from the pituitary. When beginning PCT, switch to another AI also.
For more informtaion on HCG, see this thread I wrote:

Example of PCT:
wk 1-5 Clomid 25-50mg/ED OR Torm 120/60mg/ED
wk 1-5 Nolva 20mg/ED OR Torm 60mg/ED
*Aromasin 25mg/ED OR Arimidex 0.5-1mg/ED
*AI's are not always needed, especially if one has been used to control estrogen (aromatse activity) during the cycle. There is a high risk of lowering estrogen too low and that can bring its own side effects; Lowered labido, aching joints, poor cholesterol and can negatively effect the immune system. We need some estrogen, not alot, not zero, but one cannot afford a too low an estrogen level at this time of PCT.
One should also add a cortisol reducer. The best most effective and cheapest way to reduce cortisol is Vitamin C. Take 1g apon awakening and a further 1-2g PWO.

Tribulas or another labido enhancer (Proviron).
Designer Steroid/PH cycle inhibiting the HPTA
wk 1-4 Clomid 25-50mg/ED OR Torm 60mg/ED
wk 1-4 Nolva 20mg/ED
Trib or another labido enhancer.
Thats it. Read the sticky's.
There are far too many "What PCT" threads here.
