I ran out of tri mix a year ago switched to edex never got rock hard so I thought it was the tri mix other ingredients that edex did not have keep bumping up my edex 30 units 40.45.50.up to 70 still only 80% so I tried a 20 mg of calis then 30 units edex better but only lasted 20 mmin keep going up till 50 units of a 40 edex 20 mg calis bingo rock hard 1 hour plus
