this is what i found so far. this study was done by Dr. Michael Scally. im posting this cause i found it very informative and i will definitely implement this for my cycles

they actually revised the protocol to HCG: 2000iu for 20 days administered eod; nolva 20mg twice daily for 45 days
and this was the study that was done
Methods
An uncontrolled study of 19 HIV-negative eugonadal men, ages 23 ? 57 years, administered testosterone cypionate and nandrolone decanoate for 12 weeks, and then were treated simultaneously with a combined regimen of human chorionic gonadotropin (hCG) (2500 IU/QODx16d), clomiphene citrate (50 mg PO BID x 30d) and tamoxifen (20 mg PO QD x 45d), to restore the HPGA.
Results
Mean FFM by DEXA increased from 64.1 to 69.8 kg (p<.001); percent body fat decreased from 23.6 to 20.9 (p<.01); strength increased significantly from 357.4 lb to 406.4 lb (p=.02). No significant changes in serum chemistries and liver function tests were found. HDL-C decreased from a mean value of 44.3 to 38.0 (p=.02). Mean values for luteinizing hormone (LH) and total testosterone (T) were 4.5 and 460, respectively prior to androgen treatment. At the conclusion of the 12-week treatment with androgens the mean LH <0.7 (p<.001) and total testosterone was 1568 (p<.001). The mean values after treatment with the combined regimen were LH=6.2 and testosterone=458.
he also goes on to say about usage of AI in pct
I now strongly believe that an AI should be used as long as there is an aromatizing compound being administered. In this case Testosterone and HCG aromatize therefore using an AI until these meds clear is now what I am recommending. There is some evidence that adding Nolva to an AI does not increase the effectiveness of estro control therefore Nolva has no real advantage alongside an AI unless one is experiencing gyno. Additionally Nolva has been shown to reduce IGF-1 and GH levels. This is not a big deal on cycle as testosterone increases IGF-1 in a dose dependant relationship. However off cycle this is a problem. PCT is a fragile time and lower IGF-1 and GH levels is not desireable as I am sure you can appreciate. The last few days I have been relooking at AI's to find one that is specific to men that can be used on cycle and during PCT. It is my conclusion that Aromasin is the obvious choice.
Aromasin (Exemestane) is a Type-I aromatase inhibitor, or suicidal aromatase inhibitor. It?s called this because it lowers estrogen production in the body by attaching to the aromatase enzyme, and permanently deactivating it. (1)
Personally, I find this to be a very interesting mechanism of action when compared to type-II aromatase inhibitors, which bind competitively to the aromatase enzyme, and eventually unbind, rendering it active again. In the case of Aromasin, this doesn?t happen, and once it does its job on the enzyme, those particular enzymes will no longer function.
Because the enzyme is permanently deactivated there is no estrogen rebound with Aromasin. Estrogen rebound at this critical time during PCT is undesirable so using Arimidex would be inferior. Therefore I believe Aromasin is the AI of choice during PCT.
