imo it all boils down to the source and his desire to ensure that the product meets the label. Lets be frank. Test is very cheap and should always be clean regardless of price. Much of it is made domestically with imported powders, so I don't buy the ole "I didn't know whats in the bottle" it doesnt have to cost what some of these guys charge. But... if you are willing to pay it, they will have it for you. Expensive isnt always better, but a good cheap source with the integrity to make sure product meets the label can be difficult to find. I have had cheap test that worked well and expensive high dose test that wasnt worth a shit. With that in mind we bros usually go by source/product hype, then source rep, then how we respond to it. Solution, find a guy you feel you can trust over time.
