The go-to gainer

Taste is great and best of all it actually works! If you've got a fast metabolism or just live an active life and have no time to meal prep, get this. 10/10

LOVE THIS PRODUCT

This is my second purchase of this product. I’ve tried others but nothing comes close to this mass gainer in my opinion. It does what it’s supposed to do and the flavour is rich.
