    It definitely does what it says. My metabolism speed up a lot. I noticed I started to get hungry almost immediately after I ate. I thought something was wrong but then I called GPR and the guy said it was normal when using the 878. I couldn't believe how fast I was toning up. Some ladies from my spin group wanted to know what I was on so I told them about my secret lol

    Heard about the 878 when GPR came to Myrtle Beach, SC. The rep was HUGE and recommended me this IGF-1 product. So me and my buddy got a few bottles and it's the best hundred I ever spent. Veins all over my forearm, body fat went down, great energy when training, not sore after heavy workouts i mean this stuff is VERY legit!

    I gave this stuff a try the other month. body fat dropped 3%, got toned and metabolism is off the charts. I just ordered a 6 month supply. Hopefully it can help me out through all these holiday meals lol

    I started using this product a few weeks back and immediately noticed that little pudge on the bottom of my stomach going away lol. started getting hungry every hour from burning almost anything I ate right away. veins, definition, wasn't getting sore after workouts and just felt amazing. it's pretty incredible, u just have to give it a try. I'm writing this review and I just noticed they lowered the 1oz to 70 bucks and can get doublt for 100...SCORE!! lol i bought this when it was selling for $99 hahaha. it's gonna be a great day! :)
