Excellent. Fortagen and Cyntronium

Works for me best pre-workout for an additional boost. No jitters and taste is not that bad - especially with club soda. Great custormer service.

The price may initially give the uninitiated a heart attack, but read the fine print, break it down by number of servings, and at the end of the day, its still a pretty darn good deal!

This product is an excellent substitute for coffee in the morning.

Helps me ween off of diet soda junk. IN-Perium mixes well and tastes good and does not give me the jitters. Great customer service.

Taste is great. If you are sensitive to caffeine, only use a quarter scoop or half scoop.

I start my day with IN-Perium and then complete my X3 workout!

Ive been taking In-Perium for years and I love it. Tastes really good instead of coffee I drink this instead. Yes I drink it hot and it makes an amazing morning pick me up drink.

Best Product on the market

Great alternative to soft drinks! I mis in with seltzer water and enjoy a jolt of energy without the jitters.

Great product. I use this in lieu of coffee. Perfect amount of caffeine and electrolytes.

I take this everyday. I highly recommend this. Tastes really good, gives me great energy and focus without any crashes.

Not to mention it taste so good when its iced! I dont go a day without this product

Great clean preworkout product with no junk

I use this daily. It has helped me reduce my coffee habit. It gives me early mental clarity without the crash, helps with my morning workouts.

Bought this for the hubby to try, needless to say he will only use this from now on. The taste will take some time to adjust to but totally worth it!

I'm using it daily for more than two years and it is great.

All the energy you need without the jitters. This is not just a pre workout fir me this is a energy boast whenever you need it clean and easy

I find in-perium gives me the boost of several diet drink without the nasty chemicals. works throughout the day for me. Great customer service.

Taste great and gives me energy for the day.

Really like the focus/mental energy without jitters or tingling. I find it is great to take before a lunch workout and gives me decent energy the rest of the work day post workout.

I feel energized and focus and I’m able to complete my work shifts perfectly with no crashing

Works well for me without jitters. I use in the morning for work and pre-workout. Taste is fine. I mix with sparkling water.

I’ve been using this for years in place of coffee. It’s delicious.
