1. By jnm610 from goshen, indiana – “Excellent Product!” 5/5 stars

“I would recommend to people with at least a little muscle mass on them already.I take like the instructions say and by the time i get off work i am pumped and ready to lift. And during the day when im working my muscles tighten up and crave a good punishing,so here’s how i take them… 2force factor in the morning with two ramp ups(full glass of water to eliminate heartburn from the ramp ups)and then two of each a 1/2hr before lunch and like i said,by the end of the day im SUPER pumped to lift and what a workout i have!!”

2. By dj.brock1 from Springfield, MA -  “Recommend this” 4/5 stars

“I don’t see what these other results are talking about because i’ve been using this for three weeks and i definitely see results. I’m a track athlete and can tell that i have more power in my legs when i run and jump. I can also see a dramatic change in my muscle size. The price is a bit high and it is kinda of annoying to try and take before a meal, but I still would recommend this product. I think this product should mainly be taken by athletes who are working out five days a week.”

3. By ksiedeski from fort myers, florida – “This stuff works so much better!” 5/5 stars

“This stuff is awesome and I have to say i imediately noticed a difference within two days of starting it. i dont know some of the bad reviews below said, but those people prolly didn’t combine it with a good diet or enough reps. force factor helps you get past the comfort zone during a workout to the place where you start seeing real results. a little pricey, but worth every penny in my experience.

p.s. no side effects, which is good if you don’t like a ton of caffeine or jitters after your workout.”

4. By Brandon from St. Joseph, MO – “Wow!” 1/5 stars

“this stuff is amazing!!!! I am only 15 years old and i have used force factor for three weeks. it really gives you tons of energy and makes you twice as big and pumped in half the time! i used to weigh 182 pounds three weeks ago. i was chubby. now only three weeks later i weigh 169 in muscle. i can bench 180 now and can curl 60 pounds. THIS STUFF IS AMAZING!!!!”

5. By alucas1167 from Seattle – “I feel the difference” 4/5 stars

“Everytime I take it, I can go the extra mile.
Force factor gives me that edge I need to finish strong and can see the difference.”
