Hi Daann01,
Personally I would not run insulin pre contest or pre workout at all. It's a storage hormone and regardless of having your carbs in check, in my opinion not worth the risk here. Your stack along with 3g of creatine, electrolytes & plenty of water will take care of your fullness for your workout
Same with the GH pre workout. The GH would be better suited to first thing in the morning to combat cortisol levels and get some good fat burning affects going
I have reviewed Bio Science GH here (
https://mtsboard.com/threads/1367-Bio-Science-GH-Review). In my opinion it is superior to Medtropin ( i've used both)If you were to run 1 kit, it would last 22 days @2iu's ED. Alternatively I recommend 3iu's ED (2 kits lasts 30 days) I have had great results during my growth phase and will be charting progress as I transition into my prep in May.
What will your diet look like for the start of your prep?
Cheers
JP
