I am just waiting my 1st order Depo-Testosterone (Cypionate) to arrive, FML that I spent hrs on searching on the product, where to buy etc i didnt realized syringes is also an other learning curve so here i am again at your mercy oh mighty knowledgeable people. I was told to use 25g to withdraw and 18g to inject, but how long does the needle has to be, didnt know there are so many options. I have got the link of where to order from my question is do i need 18G X 1" or 18G X 1 1/2" for the injection?
