@pep_researcher That was me, lol. I’ve been interested in this topic for some time now as an avid user of the Nexaph Tesa/Ipa blend.
There has been a huge back and forth about this. Many vendors have seen decreased Tesa purity results from Jano since around April/May. Claim was that they changed their testing procedure and discounted an impurity. Nexaph had their tesa retested at Freedom which came back at 99.9%. This was another instance which caused people to doubt Freedoms results. No domestic labs have shown lower purity numbers on Tesa, like Jano has.
Some vendors have not shown decreased Tesa purity though, which makes me wonder if it is an actual issue with some vendor’s Tesa, and not a change in lab testing.
Either way, the product has worked great, doubling my IGF.
