No they were/are crap! I had lymphoma and the chemo gave me type 2 diabetes. I have had medical training. I did not want to use the metformin or glyburide to treat the diabetes as these agents don't effect the insulin resistance that causes the diabetes. Testosterone has been show to increase insulin sensitivity. I bought some andor-diol in bulk, chinese i'm sure, and tried it at 400mg twice per day. It worked right away. after one day my blood glucose levels were normal. I took it for seven days and stopped. My blood glucose levels stayed normal for three more weeks. When they started to go back up I did seven more days. They dropped to normal again. I then bought a bunch of PA's andro 300. It didn't do shit!!!! Had no effect what so ever on my blood glucose levels. I had some of the bulk ando left and it worked just fine. I don't think there was any ando in PA's stuff at all!!!
And by the way I have completely cured my type 2 diabetes with my own therapy. I think this is the real reason the "medical industry" went to the president and asked him to ban andro. I didn't just come up with this treatment out of thin air either. It came from published articles from the Journal of Endocrinology that studied andro.
