See one issue is that we have almost all had issues with bad sources, labs etc in the past. I've discussed on podcasts using (fortunately given to me for free) completely fake DBol. 10 days no results at all. The legit stuff arrived and 4lbs up in 4 days.
Ditto we see members that have trusted a source and put a $1000 out (or more) and not even had any product arrive.
We've even had sources that were great for a year. We liked them. Products were GTG... and then NOTHING. No product, scam products, money lost. They've been dropped so quick we got burns lol. Once they dropped the ball we dropped them. This has been stupidly frequent on the Oz forum and so recent changes have meant they (sources) pretty much have to build up trust over time before being rated well.
Now we don't wanna have to explain this each and every time. So we recommend sources we've seen tested (as in products to labs), brought and used by members, that we personally have used and so on. Most of, if not all, of our fave sources post lab tests as well as have been tested independently by members for their own peace of mind. We 100% work with trusted sources who also support this very forum that enable newbies to ask about which source to use.
Ergo I've used and trust products from PSL, NapsGear or UGFreak
