Genuinely noticed a difference

Been using the Energy formula for about three months now. I'm not someone who normally feels much from supplements but this one I genuinely noticed. Clean lift, no jitters, and no crash an hour later.

Excellent value

Tried a few of the bigger brands and Science Fitness honestly stacks up. The pricing is fair, dosing is sensible, and it actually works. Will be ordering again.

Hydration is brilliant

I do a lot of cycling in summer and the Hydration mix has become a staple in the bottle. Mixes well, doesn't taste artificial, and I'm not cramping the way I used to.

Matt R Verified

Sleep has improved

Started taking the Magnesium Glycinate before bed on a friend's recommendation. Falling asleep easier and waking up feeling more rested. Genuinely impressed.

My ranked-night staple

4Gamer is sharper than an energy drink and my aim doesn't fall off a cliff at midnight. Wish I'd found it sooner.

Liam Verified

Works well, stiff lid

The Recovery mix genuinely helps with DOMS after leg day. Only gripe is the lid can be stiff to get off with sweaty hands — hence four stars.

Chris M Verified

Dangerously tasty

Have to stop myself eating the gummies like sweets. Nice steady lift for the afternoon slump at work.

Becca Verified

Good value magnesium

Does the job for post-gym tiredness and the lemon flavour is pleasant. Knock a star off for the fizz taking a while to settle.
