"250 mg testosterone per week per 1 IU growth hormone per day or something. Does that recommend still stand... that recommendation still stands. If you're purely looking for the anabolic synergy where you get the most bang for your buck out of steroids combined with growth hormone, I would say 250 mg steroids..."

"when is the best time to dose growth hormone towards the end of a cut? Should I split up dosages... I would just take it at night to help with sleep quality cuz honestly, the fat loss benefits from growth hormone are greatly exaggerated. The maximum dose with 1.2 IU's, 1.5 IU's to get lipolysis."
