My normal TRT protocol is:

60mg cyp every 3.5 days
HCG 250 IU M-W-F
No AI needed

Went to this:

80 mg every 3.5 days (dropped this back after handful of weeks)
HCG same
Vit D (Drisdol) @ 50K IU once per week
Stinging Nettle @ 480mg per cap x 3 a day

I wanted to try and get it down fast then hope that adding in the D and Nettle it will maintain at its lower level. Time and BW will tell.
