Nice little write up. Thanks for the info.I recently tried Supp-D and have to say it literally blew away my expectations. I've tried numerous other pre training supplements and they were either too strong, not strong enough or left me with a bad crash. Supp-D was perfect! Great energy without the "cracked out" feeling. Drive to add another rep or cut my rest time each and every time. I never built up a tolerance either. The focus was amazing as well seemed like I was the only one in the gym. The only negative for me was the lemon taste of the Rasberry Lemon flavor but then I've never been a lemon fan. I feel great and very confident in recommending Supp-D to anyone looking to leave it all in the gym!!!
