A solid pre-workout, but with lots of caffeine.
A quick overview of the ingredients:Caffeine - a powerful stimulant for both physical and mental alertness and performanceCitrulline and ornithine - key components in nitric oxide metabolism which decreases fatigue by increasing blood vessel size and flowBeta alanine - reduces lactic acid production (alleviates the burning feeling in muscles during exertion), but creates tingly sensation on your bodyTheanine - alleviates side effects of caffeinebetaine anhydrous - typically used to treat homocystinuria, in here probably used for methionine production for muscle synthesis. Also, a few studies suggest 3~4% increase in peak power when used. Still, considerably a less important ingredient compared to the others.Stevia: for sweet taste to mask otherwise bitter tasting ingredients*3 major ingredients that really matter: Caffeine, citrulline, beta alaninePros:1. Performance: Pulse should work for most people, ranging from weight lifters to runners / cyclists / other cardiovascular workout enthusiasts.2. Dosage: Contains recommended dose (or more) for each ingredient appropriate for workout enhancement purposes, whereas some other pre-workout brands often contain a fraction of the recommended dosages.3. Convenience: You don't have to buy and mix each and every one of them. You don't have to calculate or measure micro ingredients.Cons:1. Cost: $39.97 for a 1.25 lbs jar is rather pricey. If you want to sacrifice the convenience, you can buy the ingredients in bulk and make your own pre-workout for much cheaper.2. Caffeine: 350 mg of caffeine per 2 scoops. 175 mg per 1 scoop! That's almost 4 cans of mountain dew in every scoop! You are going to build up caffeine tolerance if Pulse is taken regularly, and if you feel like Pulse is no longer working for you a while, (or if you think Legion somehow changed Pulse's formula, etc), it could very well be a caffeine tolerance in reality. You can reverse caffeine tolerance by taking 1~3 weeks of break from caffeine, but that means you can't take Pulse (and other non-caffeine ingredients in Pulse) during that time. However, I decided to not take a star off because other top two pre-workout competitors have equal or more amounts of caffeine.Neutral:1. Taste: Tastes okay for me. About 8 parts apple juice taste, 1 part 'medicinal' taste, and 1 part bitterness. However, Pulse still subjectively tastes better than, say, most whey protein mixes I've tried. Also, adding more water helps to make the taste better.2. Tingly sensation: This is due to the presence of beta-alanine. Because people tend to take stars off from this issue, some (less popular) pre-workout manufacturers started to remove beta-alanine from their pre-workouts. The tingling sensation is harmless, and beta-alanine is too good to dismiss just because of the tingling.Edit: turns out even if you mentally/subjectively do not feel the effects of caffeine anymore, it still boosts your performance nontheless;[Gonçalves et al.
