Energy & Focus
iSatori ISYMFS Pre-Workout Amplifier features quite a bit of ingredients in its formula and is pretty intense. It may certainly improve workout performance for many individuals; however, there is a ton of caffeine in each full serving. If you don’t handle caffeine well, this pre-workout may not be for you.
- Side Effects
iSatori ISYMFS Pre-Workout Amplifier is a supplement designed to improve energy, strength, and your muscle pump during workouts.
This pre-workout is part of the CT Fletcher Series under iSatori’s line, featuring an acronym CT Fletcher made famous in the gym, ISYMFS. If you don’t know what that stands for, a simple google search will tell you!
Here’s a look at everything there is to know about iSatori ISYMFS Pre-Workout Amplifier. Is it a crazy, intense pre-workout, or is it simply forgettable?
At first glance, iSatori ISYMFS Pre-Workout Amplifier appears to be quite a powerful supplement. It is very stimulant heavy. Here’s a look at a couple ingredients in iSatori ISYMFS Pre-Workout Amplifier:
Beta-Alanine (2,400 mg)
Beta-Alanine is used to improve fatigue and muscular endurance. Those that supplemented with beta-alanine during experienced an increase in workout volume during the bench press. Fatigue during exercise was also attenuated. 
Consequently, it may help improve lifting performance in the gym and support your muscle and strength-building results.
HPLC Verified Creatine (3,000 mg)
iSatori ISYMFS Pre-Workout Amplifier features 2 creatine forms of creatine, monohydrate and HCL.
Creatine improves energy levels and power output during resistance training.  People that supplement with creatine usually supplement with it every day, regardless of whether they are training or taking a rest day.
Caffeine (425 mg)
That’s right, iSatori ISYMFS Pre-Workout Amplifier is crammed with a bunch of caffeine in various forms: creatine anhydrous, caffeine citrate, and di-caffeine malate. Caffeine is a stimulant used for enhancing energy levels as well as focus and cognition. 
This ingredient may help rev up your energy in the gym and also help improve your mind-muscle connection.
Black Pepper Extract (5 mg)
Black pepper helps improve absorption and bioavailability of ingredients.  Consequently, black pepper extract might help boost bioavailability and absorption of all the ingredients within iSatori ISYMFS Pre-Workout Amplifier.
Betaine Anhydrous (1,500 mg)
Also known as trimethylglycine, is used to combat fatigue and enhance power output; however, evidence surrounding this benefit isn’t conclusive.
One study shows betaine supplementation failed to improve power output but was able to minimally affect fatigue.  Another study reveals betaine supplementation didn’t improve power output or perceived fatigue. 
However, it may offer some workout benefits, especially overtime, but I can’t be sure.
iSatori ISYMFS Pre-Workout Amplifier features some effective ingredients and appears to be quite intense. If you’re new to pre-workout supplements, iSatori ISYMFS Pre-Workout Amplifier may be a little much for you.
Is iSatori ISYMFS Pre-Workout Amplifier Dangerous?
My main concern with iSatori ISYMFS Pre-Workout Amplifier is the amount of caffeine per serving. The caffeine in this pre-workout is one of the higher amounts I’ve seen in a pre-workout in a long time. If you don’t handle caffeine well, you may experience insomnia, stomach irritation, nausea, and vomiting. 
How Should You Use It?
iSatori ISYMFS Pre-Workout Amplifier should be used anywhere from 10-20 minute before working out. You’ll have to experiment with optimal ingestion times.
The directions state you should mix 1 serving with 5-6 oz of water. One serving is 2 scoops. So, if you are unsure how you’ll respond to the ingredients, you can start out with 1 scoop. After you’ve assessed tolerance, you can increase to the recommended 2 scoop amount.
Pricing & Flavors
iSatori ISYMFS Pre-Workout Amplifier comes in several different flavors, including Blue Razz, Fruit Punch, Mango, and Watermelon.
Each bottle packs 20 servings and costs $35. If your preferred serving size is 1 scoop, one bottle will provide 40 servings, and the price-per-serving is not bad; however, if you take the full, recommended serving, iSatori ISYMFS Pre-Workout Amplifier may be a little pricy.
