How much caffeine is in PER4M?
One scoop has 200 mg of caffeine, about the same as two cups of instant coffee. Two scoops (the hardcore serve) has 400 mg of caffeine. Food Standards Australia New Zealand suggests most healthy adults keep caffeine to about 400 mg a day from all sources, so the hardcore serve is your whole day's caffeine. Count your coffee, energy drinks and fat burners too.
How to take PER4M
Start with half a scoop to test how you handle PER4M. Then move up to 1 scoop (8 g) in 400 ml of cold water, or the hardcore serve of 2 scoops (16 g) in 500 ml of cold water. Drink your PER4M about 30 minutes before training. Do not take more than 2 scoops in a day, and avoid PER4M close to bedtime.
Flavours
Blue Sour Straps, Citrus Bomb, Grape Xplosion, Passionfruit Slice, Phantom Drop, Red Sour Straps, Sour Apple, Sour Black Currant, Sour Peach, Sour Pine Punch, Sour Watermelon, Ultra Psycberry and White Blizzard. Not sure which to choose? PER4M is covered by our Love the Taste Guarantee. Try up to 5 serves within 30 days. If you don't love the flavour, swap for another or take store credit.
Size and price per serve
One 400 g tub is $79.95 for 50 single-scoop serves, about $1.60 a scoop. At the hardcore serve, you get 25 serves at about $3.20 each.
Who should take PER4M?
PER4M is a good fit for experienced pre-workout users who want strong energy and sharp focus, lifters who train with high intensity, and anyone who trains hard and handles caffeine well. PER4M is not for beginners at the hardcore serve, people sensitive to caffeine, anyone under 15, or pregnant or nursing women.
Side effects
Beta-alanine can cause a harmless tingling feeling on your skin (paresthesia) that fades within an hour or so. High caffeine can cause jitters, a fast heartbeat or trouble sleeping. Start with half a scoop, don't take PER4M late in the day, and stop use if you have any adverse effects. Talk to your doctor first if you have a heart condition, high blood pressure or take any medication.
What to take with PER4M
- Creatine: PER4M has no creatine, so add 3 to 5 g a day of Booty N Buff Essential Creatine or Optimum Nutrition Micronized Creatine.
- Protein after training: Dymatize ISO100 or Rule 1 R1 Whey Blend.
- Electrolytes: Dr. Hydrate on long or hot sessions.
