I'll have to go look at you may be right but as I recall the greys tested consistently in the high 9iu range. But that is just going off my faulty human memory.Also alot of testing i have seen on the greys have the dosage coming back 7,8,9 iu not downing the product just stating what i have seen im sure some have been 10iu also
All those tests are really not pertinent any longer though since TP is now getting his greys from a different "GMP certified" factory. That's the story anyway. I'm always skeptical about sources claims but TP does have an extensive excellent track record.
