LIMITED TIME ONLY: I'm delighted to offer you a discount for the Health Optimisation Summit in London.

I'll be back as MC this year, and you can use code TONY for 10% off your ticket.

It's the best health and biohacking event in Europe. See you there in September.

Today: two devices built around light — one for your pain, one for your brain.

But do they actually work… or just look good on Instagram?

This is our reviews episode — where we test trending biohacker tech so you don't have to.

Dr. Richard Blake is a podcast regular, but this is the first time he's been on as a doctor! He is a mental health and breathwork coach, the co-host of Runga Life podcast, and holds a PhD in psychology. Follow him on instagram.

THIS REVIEW SHOW IS BROUGHT TO YOU BY:

BiOptimizers Sleep Breakthrough and Magnesium Breakthrough

These are BIOptimizers sleep and magnesium supplements which I take every night.

I have also been using the new Magnesium Breakthrough drink - delicious way to get magnesium. I have been putting a scoop in my protein shake after a workout.

Just go to BIOptimizers.com/tony and use code TONY10 for at least 10% off (often more). Code works worldwide, and on all their products.
