I have it, saw labs on someone running this and go there test to around the 540 level from 400. To be honest I still have some caps left, I dont like how they put arimastine in it, 5 days in and my joints start hurting. Same with the ksm don't like it in there, other than that it was alright. Nothing mind blowing on this supplement, could of been better made with diff ingredients. It does help with my digestive issues though that I will say.
