The fade is gradual and it doesn't announce itself. You don't wake up flattened one morning. You just notice, slowly, that it's costing you more to get the same back. I wanted more from what I already had, and that seemed a reasonable thing to want..

Plenty of the men I talk to are in the same place. Nothing necessarily wrong, still active, still turning up. Just after a bit more from the effort they are already putting in.

In 2015 I bought into a supplement company. The partnership fell apart and I was left with a choice: keep TESTO or walk away from everything. I kept it, because by then I'd been taking it myself and I knew it was right.

I'd also spent thirty years learning what happens when you stop. Four elbow fractures between 15 and 30. Six surgeries. My left arm still doesn't fully straighten. At the gym I modify, adapt and get on with it, because stopping is the one thing I know makes it worse.

That's the principle behind TESTO. Keep moving.

I worked with natural health and formulation specialist Jenni Lane to improve the formula to what it is today. Every ingredient chosen for a reason, dosed to work, not to impress on a label. It's still part of my daily routine and has been for years. My partner Deb noticed before I said anything. She noticed the difference when I was consistent, and when I wasn't.

I'm 60 now. Still training four days a week. Still managing the same injuries the same way. The body responds to what you ask of it. Stop asking and it stops responding.

If you're still showing up and you want more from it, TESTO is for you.
