I think people in doubts should take a systematic approach to this problem (not responding).
It is all about finding good and reliable source/producer - I would also like to find one and ideally get it tested but where and how? When I read the article about how online sellers cheat I was a bit upset but what we could expect, right.
It is easy to fool individuals - who can order 3-4 vials and get random one tested in some lab? The only tactical solution I see is regular testing of the samples - standard quality assurance. It should consist of:
0. Found some alliance/group of users who have same concerns (health protection, interest in quality products, paying some add. fee is acceptable)
1. Contacting those guys who wrote the below article and find out what would be needed to get some product tested. What is the cost associated.

2. Enter some type of agreement with the lab and using its services we can try to find good sellers. It can cost some money upfront but I personally don´t see money a biggest problem, more over if it would be shared by more people. Safe product is priority.
3. Repeating the random tests - for example each member of the group would need to make an order for the Lab check purpose once a year or similar - just to ensure the quality does not degrade.
4. At the same time people could take notes and share the experience with others.
What a crazy idea right?
People should not inject whatever someone sends them online ... just to see if it works or not.
If someone is not responding any more ... then it can have also different reason ... however more people would need to confirm such thing. If sellers cheat more and more it is all about the amount.
I remember how much time I spent with the calculations and guess what - all was probably wrong. My 10mg assumption made all completely off and dosing is IMO very important. I also remember how the experienced guys repeated dosing is important, do not overdose, just 0.25 mg is enough etc. but they probably obtained this experience with 10 mg vials. LOL. There were lot of people who claimed it is just not working for them and claimed they do 0.5-1.0 mg per dose and then results arrive. I think it is clear where I´m going ...
From my own experience I can also say the progress is non-linear - nothing, nothing, ..., something etc. and most people said the loading phase is after 10 mg like 13-15mg. This means that based on the article findings it would require people to slowly consume 3 vials .. I repeat 3 vials ... to get on the right path. In the meantime they injected tiny amount with lots of UNKNOWN stuff and watter. Who is that patient?
If I start really guessing ... WARNING. It can also work the way tiny amount gets lost - nothing in your body will happen, like if you are drinking shot of beer on daily basis and wondering why still not drunk ... Just kidding.
Anyway we need to stick to known facts: lots of positive experience, sellers who send vials with up to only 43% of claimed amount. People thinking they dose 0.5 mg actually dose 0.2 which means that when injecting every other day they would need perhaps up to 75 doses to reach the threshold/breaking point. 75 * 2 = 150 days. Is anyone going to inject unknown stuff without visible results for 5 months?
