Our story
We're two friends who train together in London and grew up on opposite ends of the Mediterranean. We wanted something light to drink after training, that tasted like home. So we're making it.
The SAYF founders
It's whey protein isolate that mixes into a light, juice-like drink instead of a thick, milky shake. Same protein, much more refreshing after training.
Creatine is one of the most studied sports supplements, and most people who train take 5g a day. We put that dose in your daily drink, so you don't need a separate tub.
We're aiming to launch in spring 2027. Everyone on the waitlist gets first access to the Discovery Pack before it opens to the public.
We'll share pricing before pre-orders open. Waitlist members get early-bird pricing.
No. It's made from whey, which comes from milk.
