The best of them all

Review by Karan on Aug 5, 2020
This is the best pre-workout I have ever had. I have previously tried NO Xplode, Assault, Ronnie Coleman, Evlution nutrition shred. But this is the best.

Not impressed at all

I cannot say that I m really impressed absolut this product at all. I ordered the bubble gum flavour, thinking abot the ABE pre workout that I have used before. You can not compare it with ABE! Also as a preworkout and also as a flavour. ABE is much better from all points of view. I would not buy this product again. It’s a waste of money, not giving any added value to your workout.

Super hoog gedoseerd

Review by Anonymous on Sep 3, 2023
De smaak is echt super ranzig, waarschijnlijk doordat hij zo hoog is gedoseerd, je proeft gewoon de bittere chemicaliën nog. Maar de energie die je er van krijgt is echt niet normaal meer. 7g citruline 4,8g beta alanine, 300mg caffeïne, wat een formule zeg. Als je een beetje schijt kan hebben aan de smaak en het gewoon naar binnen werkt is het echt de beste pre-workout die je zal vinden, al helemaal voor deze lage prijs.

C4 is ranzig, maar werkt wel goed.

Review by Gast on Jul 26, 2023

4 verschillende smaken ultimate C4 in de aanbieding besteld, ze werken goed maar de smaak is abyssmal. Er bestaan geen worden in de Nederlandse taal die kunnen omschijven hoe goor deze smaken zijn. 0/5 De caffeine werkt wel heel goed. 5/5 Proef je niks? Ga voor C4.
