I think its quite an interesting question this! In my experience, you gotta get ripped off and go thru trial and error until you find "a good source" For me, it started off asking the biggest guy around, paid an arm and a leg, lol, remember paying R20 for a single winstrol pill, lol, yep with R100 i used to get 5 tabs and thought i was the man! Turns out those tabs were in fact fake anyhow! From there if you take a real liking to juice and training, you start researching(internet) and if you lucky enough, stumble on something, take a chance and either get ripped off or come right! As you keep researching, meetin new ppl, fellow gym rats....You build relationships and find your source...Well, in my experience anyhow. I would think its a little harder to get a source now thou cos of the bs media sensationalizing it.
