It's ok, it's not another "Can I mix Test and Tren in the same syringe" thread.
My question is more on the subject of the best way of doing it.
23g Pin ok?
Just pull 1ml out of the vial of Test. Push out some air. The pull out 1ml of Tren. Both 10ml vials.
Simple as that? My curious to whether there's a chance some of the Tren will leak in the Test vial. Even if it did, would it matter anyway. My thoughts would say no.
