High quality no crashing after use quality product for people who need that extra boost in the gym after a hard day's work.

### ⭐ Terrible
*by D***D on 2 February 2024*

This tastes absolutely terrible like paint and has no effect on my workout such a shame as the original c4 is absolutely amazing. Should have stuck to that as I’m unable too return or get a refund on this product so wasted money on something that’s just going in the bin. Stick to the original
