These energy formula supplements are amazing! They give me the boost I need in the morning for mental clarity and alertness. I don't get a jolt that makes me feel nervous and I don't get a crash either. They are wonderful. I've used these for many months and I'll continue to use these for many more to come.

Love these supplements! I am in my mid 50's and have been using this product for yrs to gain and maintain my energy levels throughout the day as I need it. My job can be quite physical at times. These supplements don't give me the jitters like some energy drinks and supplements do, but leave me with a feeling of increased alertness, energy, and endurance to make it through whatever I need to get done. And added plus for me is that they're herbal.

I tried a couple different powder pre workouts and they were good but they all had an after effect of nausea and when i use this i do not get that. I do get energy and feel good the only difference is powder pre work out works right a way this takes about 30 minutes to kick in but i am okay with that.

Works great for me. I was looking for something to keep me focused on my work (I do lots of paperwork) and give me energy to get through my 2nd job. It does just the trick. No jitters. No headache. I have been taking about 15 days now. Noticed a difference right away. Definitely will continue to purchase.

I purchased a bottle and it arrived as GNC said. My first day I took a pill in the morning and one at lunch. My mental clarity and energy was awesome. My wife took one before work, came home for lunch and was a complete different person attitude wise with the same results as myself. We will order more. There were no jitters and no crash as with many other products.

Usually when I take B-12 for energy supplements, I get somewhat hyper to the point that my doctor said stop taking them (it could be the product I was using contains caffeine, but not really sure). Anyway THIS product is different, it works during the day when I need energy the most or when I'm working out, but it doesn't affect my sleep. And that's awesome!

At first I didn't think this worked because I've got a tolerance to caffeine so I take stacker 2 and Stacker 3s so I took two to start and then ended up taking two more and for me that's what it work then it was a very mild awake feeling but for me it took a while when I realized I wasn't going to bed anytime soon LoL not bad for A Cbc prosuct

It didnt really give me the energy I was expecting, although after a while I started feeling more awake but didnt give me the effects I was looking for where I needed it. I would recommend for someone who needs that boost but over all I still feel tired while taking it.

I was looking for a supplement to help boost my energy. I had chemotherapy that ended in April 2019 and it takes a lot time to recover from it. I'm 65 years old so I thought this product would be a good help. Believe it or not I just took my first capsule this morning and within an hour it made me feel jittery and a little off. I was so hoping this would work but I guess it isn't for me. I do have some anxiety so I think for those that have anxiety, this isn't what we should take.
