Customer Questions & Answers
Customer reviews
LOVE the flavor, great value with the subscription!
Reviewed in the United States on January 8, 2021
FLAVOR: I would describe the Strawberry Watermelon flavor as the same as a natural Strawberry popsicle. The strawberry flavor definitely comes through more than the watermelon, but I don't mind because I'm not a big fan of artificial watermelon flavor. I prefer this brand to other energy drinks because the flavor is not as overpowering and there is NO ARTIFICIAL color! I will never understand why companies feel the need to add color to a beverage in a can -___-ENERGY: The combination in the C4 carbonated drinks is nice and not too stimulating for me. As someone who has been taking powdered PWO for years, I know what I like...and what I don't. This combination (I think it's the "betapower") is stimulating, but there isn't too much beta alanine so it doesn't make me itch like some PWO's do. Total caffeine per 16 oz can is 200mg.VALUE: My husband and I absolutely LOVE the C4 energy drinks and we had previously gotten them from GNC. However, we decided to try to get them from Amazon instead after having some *less than positive* experiences with GNC. GREAT DECISION! They arrived the next day with prime and they're the kind without the plastic label (YAY) so you can just throw them straight in the recycling bin when you're finished. The value is very good with the subscription (comparable to buying from the Cellucor site except no shipping fees!).
