I can only comment on the halo, I have to say, I am very pleased with the performance of that product. I didn't keep track of my weight gains because I judge my progress off of how I look in the mirror, lost some fat and gained some muscle for sure! I had no negitive sides running it at 3 pills a day, the pumps stay with you for a couple of days... What an awesome feeling! Wish they had 90 count bottles so I could have run 3 pills for 30 days though.
solo,I wanted to see what it would do by itself. I ran it 2 a day to start, then after 2 weeks I bumped it up to 3. Seriously, the 2 and 3 day pumps were bad ass! The last day I used a sample pack of c4 I had, WOW! It was arm only day, it felt like the skin was gonna rip! I respond well to things of this nature, but it was an awesome run!
