I have 30 mL of SuperTest 450, a bit more than I need, but am looking for recomendations on dosage and cycle length. I am 6'3", 275 lbs, and this will be my third cycle, but first in almost 3 years, that is why I am doing a Test only cycle. I am looking to shoot twice a week and will be cutting with B12 for the pain issues and I like B12. Should I take .5 mL twice a week for a total of 450mg, or 1 mL twice a week for 900mg?

This is the breakdown of the SuperT.
32 mg per ml of testosterone acetate
147 mg per ml of testosterone decanoate
73 mg per ml of testosterone propionate
73 mg per ml of testosterone phenylpropionate
125 mg per ml of testosterone cypionate

I have a few differnt thoughts for PCT, so lets not get into that. Test only is prefered right now, with most likely some Arimidex during cycle.
