Myself and others have already told you a few time snow, so pay attention, this will be the last time we say it. A 250mg, 10ml vial of Testosterone Ethanate contains 250mg per milliliter. That equals 2500mg of Testosterone Ethanate total in a vial. At 500mg a week, you would need 2 vials for a 10 week cycle.
I use a 1cc 30 gauge 5/16 needle. It's an insulin syringe. I able to easily hit my glutes with it. Testosterone E an other inejctable steroids come suspended in an oil. They don't need to be mixed like HGH or peptides because they remain stable and don't break down like HGH or peptides.
