First time using PF 30 Gels & PF 50 Tablets
First time using the PF 30 Gels and PH 50 hydration tablets and I cannot fault either product. I used them for training and a half marathon, very easy on the stomach and a PB to show for it. I will continue to purchase and use these going forward.

Great products
I was introduced to PH by a friend and haven’t used anything else since! The flow gel is great for long runs and makes it much easier to meet my carb requirements. I also really like the chews. They have a great taste and are much easier to eat compared to other brands. Service from the company is also brilliant!
