"i first started phentermine 37.5 on 5-8-2015 lost 31lbs in two months took a break in aug and tried the hcg but failed  i went back on phentermine after that on september 1 also i have been on the b-12 i don&#039;t get a lot of the energy effect on phentermine plus am clinically depressed so it&#039;s difficult to just get things done so the b12 helps me a lot. i only worked out until my b12 shot was out of my system when i went to the doc yesterday i was down 8lbs making my loss 39lbs in 4 mnths minus the month i tried hcg"
