I can see some value in the testing. Here are my concerns with sources sending in for testing.
Nothing stops a source from sending in a legit sample that they know will come out good whether it's a small 1mL dose or a complete vial. They can send out a knowing good sample for testing show the report and then send out under dosed/cut product.
I think it would be great if all sources offered an incentive for blind testing from there customers in the form of store credit plus product replacement. The credit would have to be for more than the testing cost as an incentive. Also it would be on the customer to not tell the source they are sending in a sample so not to make sure the source doesn't send a piece of "good" stock. This as well can be manipulated by customers trying to cut it or cross contaminate it but I would think the chance of that happening would be well below the chance of a source sending in a tampered product. This would ensure sources have no idea who is sending in product so they better make sure that each vial is made the same. It's pretty easy to send a sample to Jano and while anasci is a step in the right direction members send samples to mods who in turn send them off which again adds another hand in the cookie jar and could be altered (unlikely but who knows what goes on behind the scenes).
Pics of the lab and stock is reaching again because I am certain most UGL's are made in someone's home or apartment. Very few operations have a dedicated facility with machinery and automation. I would not like this place to turn into meso where guys are constantly telling sources to fuck off or go kill themselves. Granted it's a free board to source so your going to get some shady operations that are there to make a quick buck but it's a bit juvenile what gets posted there.
I brew my own so I don't face any issues other than getting quality raws. I don't deal with correct dosing(other than my own math) or orders getting messed up.
What would be nice is some sort of bitcoin escrow like the dark markets have that would at least make sure guys are getting packs that are correct and not waiting a month plus for things. That would be a start and wouldn't solve any kind of under dosed or incorrect product but would be a simple step that would alleviate some headache.
