Ok, Gene I went to the new store in Bayamón, PR, The Vitamin Shop. They have a lot of products and a well variety of brands. I found L-Arginine and L-Cetrulline, one tablet 750mg/250mg respectively. I take 4 of them for 3,000/1,000mg respectively. Pignogenol 50mg, Icarrin at 10% 500mg I take 4 and Tadalafil 5 mg. I don't use Doxazosin because I use Vasotec 5mg by prescription. 3 days already....feels pretty well. BTW...my blood pressure in the morning without taken the Vasotec is 122/67 with 6 to76 pulse. That desorder on my blodd pressure went bad around 4 years ago when I was passing through a bad situation, that have been overcome positively. I had talk that with my Dr. And he said that since the Vasotec is in a low dosis I will keep it until pass the Holidays so he can monitored before take any action. I will keep you inform on the stack plus in the next two weeks I will send you some pictures and videos of my training.
