sustanon 375 is made by a pharm in china for IP. It's the same as the 250 but it's 1.5cc which is where they get the 375. cant remember the name of the pharm but can try and find it again if you need it.
Sus-A-Ton.......same thing as Sustanon 250 but is 1.5ml instead of the 1ml thats where thay get the 375 from. Havent tried it yet but getting ready too.
