The interview
Who are you and what do you do for a living?
I'm James Mayhew, located in Los Angeles, California, and I'm a professional strength and conditioning coach.
How did you first hear about STEMREGEN?
I heard about StemRegen through some people I met at a networking event in Los Angeles a couple of months ago. They wanted to connect me with them because they knew my connections to the sports world, and they knew about this great product.
What made you open to trying a stem cell supplement?
I did a little background and understood what stem cells do and how powerful they are for recovery and sleep and just rebuilding different tissues in the body. I've been recovering from a torn ACL, so that's always been something that makes me intrigued into different supplements.
What specific improvements have you noticed in your sleep?
With my schedule and just the hours that a lot of us are working, getting a good seven and a half, eight hours of sleep can make all the difference. I've noticed through tracking my sleep with the Oura Ring that my sleep score has actually improved on the nights when I'm taking stem cells consistently for weeks at a time.
How has the product impacted your daily energy levels?
Before starting with StemRegen, I noticed a lot of times midday I would kind of have, like, a crash of energy, and since being on it, I haven't had that need for, like, that late afternoon coffee to keep working or, you know, just thirty-minute nap in the car. I've just been able to, you know, kind of just push through the day and not even really feel the fatigue how I was before.
When did you realize the supplement was actually working?
On week three was when I felt the moment of like, all right, it's the stem cells really helping because after a bunch of consecutive days of waking up feeling really well, it kind of clicked and I was like, 'Well, this is the only thing that I've newly added to my routine and my regimen.'
How does this help you in your professional life as a coach?
I'm with clients training seven, eight hours a day, and that requires a lot of physical energy, mental energy. It's really helping me push through the long days of the summer of training in the gym. It's actually helping me be more physically active, which in turn is helping me get better rest.
Frequently asked
Is there scientific evidence behind STEMREGEN supplements?
James Mayhew noted that he was initially cautious due to false information online, but was made comfortable when the team provided peer-reviewed studies and case studies. He emphasized that the product was developed by real doctors and backed by clinical testing.
How long does it take to feel the effects of STEMREGEN?
For James Mayhew, the 'click' moment happened at week three. After several consecutive days of waking up feeling refreshed, he realized the supplement was the only new variable in his routine.
Can STEMREGEN help with afternoon fatigue?
Yes, James reported that since starting the supplement, he no longer experiences a midday energy crash. He no longer needs a late afternoon coffee or a thirty-minute nap in his car to finish his workday.
