Sorry to highjack your thread zach!

It can come in multi vials (10ml normally) or single use amps.
It works out a little cheaper to use a vial but not much.

If you run say sust250 thats 250mg per ml.
So 250mg a week is one injection, or 500mg is two.

You need to decide what you want? Have you looked on muscletalk yet. There are detailed guides on where and how to inject.
