Water solubility doesn't matter, that's why it's a "suspension" not a "solution". Test base and winny are the same thing, just raw hormone suspended in water, which is why they're white and cloudy. I'm sure it could be done, using the special water I made up for water-based winny, but it would probably hurt like a bitch just like winny and test susp. do so why bother? Just use NPP if you want fast-acting deca

But yes I'm pretty sure it could be done, give me a sample of nandrolone base and I'll brew it up hehe.
