Nonetheless, caffeine has several potential side effects, especially if you consume too much. These include insomnia, nausea, increased heart rate, headaches, anxiety, and jitteriness or restlessness ( 4). Citrulline, which is added to some pre-workout supplements, is meant to increase blood flow to your muscles during exercise, resulting in enhanced muscle building. In terms of stimulants, you don’t get much better than Caffeine Anhydrous. It’s a pure form of Caffeine in powder form, making it the safest and most effective stimulant out there, in our honest opinion. Some research is suggesting that supplementing ornithine might reduce fatigue and improve measures of athletic performance such as speed, strength, and power in some people.

Why? Because it’s supposed to do exactly the same thing, but studies have shown that it’s not as reliable as Citrulline Malate.

Cons

As we mentioned, from first glance, Purge PRE V2 looks like a great pre-workout. It contains an optimal dosage of Citrulline Malate, which is quite rare to see. So how does it benefit your workout? Well, L-Tyrosine can boost your mind-muscle-connection, helping you to make the most of every rep that you perform. Hordenine is another ingredient that’s believed to act in a similar manner to stimulants; it’s thought to encourage your body to release more adrenaline, which might improve your sporting performance. Think about it, people all over the world consume caffeine through coffee and tea on a daily basis. But one thing that Caffeine Anhydrous can cause is jittery side effects when consumed in large dosages.

There is a huge dose within this pre workout, as with other pre workouts such as Spazmatic, this is more than the current 100 - 500mg that are being tested.It may also be used combination with arginine seems to improve strength and power, but again this is still under review. In comparison, 1 cup, or 240 milliliters (mL), of coffee contains only 95 mg ( 5). Ways to reduce side effects Anyway, the version of HydroMax that’s found in Purge PRE V2 is a patented form of Glycerol; this is believed to help keep you hydrated. Magnesium, on the other hand, may have laxative effects — especially in the form of magnesium citrate. Thus, taking too much may cause diarrhea ( 18). As a result, we consider L-Tyrosine to be a key addition to any pre-workout supplement that it’s added to.

This stimulant has been shown to increase muscle strength and output during exercise while reducing fatigue ( 1, 2, 3). We just mentioned that there was a big dosage of Caffeine Anhydrous in Purge PRE V2. Well, it’s worrying then, that this pre-workout also contains DiCaffeine Malate. As it’s difficult to determine which ingredient is causing digestive issues, you may want to try different pre-workout formulas until you find one you can tolerate. summary

Recommended Use

The suggested amount is around 700 mg - 3,000 mg to start seeing that 'pump' and seeing any extended training benefits.

If you find that you still struggle with headaches, you may want to find a pre-workout supplement without this ingredient. summaryHowever, there have been conflicting studies conducted on Glycerol. So it’s not something that we would consider to be a key addition to this pre-workout here.
