But do you guys know for a fact that your current batch of UG or homebrew is heavy metal free, for example? It's not impossible that you could know, for example if you sent it in for testing yourself. But very few do this, and it would of course increase cost of cycling canceling out the money issue.
Everyone is different, but I would pay extra for peace of mind and assurance of quality.
my concern is the powders. it would be nice to have batches tested and is feasable though idk if i would go through the effort, but i bet im not the only one interested.
I used to get german bottles of test base powder with lab essays. but due to the nature of buying any black market product you never know with 100% accuracy anybody can repackage anything.
