Yeah, when it comes to injectables, gymjunkie is on the money man, you dont want to be injecting shit that bacteria grows to easily and rapidly! We have a post here from 13 or so years back maybe longer, copied right from Muscular development where they tested various injectables and the bacteria growth on water steroids was incredible!
I was also hospitalized for 7 straight days from a water based shot , and it nearly killed me due to my trying to wait it out at home before going to the emergency room, where it was drained and then i was there sick as hell for a week! Bad shit!
