By around 40, most adults make roughly half the nitric oxide they did at 20. Ultimate 4 supports both nitric oxide pathways to support healthy circulation, energy and metabolism.
02
BOOST
Turn the thermostat back up
Greens, sea vegetables (natural sources of iodine) and seven medicinal mushrooms to support healthy thyroid function, energy and focus.
03
Women's TRx Serum
Rebalance
Testosterone matters for women too, for muscle tone, energy and drive. A topical botanical serum that supports your body's own production. Not hormone replacement.
This is the exact sequence I use in practice.

Each layer prepares the body for the next. Circulation first, then energy, then hormones. Skip a step and results rarely hold.

I love the Ultimate 4, its given me loads more energy, reduced inflammation in lower back with little to no back ache. Has improved circulation to my whole body
I am now on my 3rd order of Boost 3, ultimate 4 and the Testosterone TRx. I have noticeably more energy, less joint pain and I’m sleeping a lot better. I still get the occasional night sweat but it’s no longer every night. And my sleep score is now regularly above 90. I am 54 and hitting menopause.
Jeff’s Ultimate 4 and Boost have been game changers for my husband and I. We’ve been on them both for a month and our energy levels have gone through the roof! I’ve been dancing through the day like a little kid. No need for caffeine anymore 🙏😊
Only been using Ultimate 4 for 10 days now and I do feel like I have more energy. The test strips started off almost white but happy to say they are now registering slightly pink which means it’s working Woo Hoo 🙌
I knew Jeff designed good products because years ago I relied on 30 plus for women, so when I saw he had nitric oxide, I had to try it. I’ve been using it for two weeks and I certainly have more energy and sleep better, the arthritis in my knee has changed. I will keep using it
I am amazed at how quickly my energy increased. I have been having B12 shots every 3mths for years with no real benefit.
Ultimate 4 helped after only a few days and it tastes great.
Taste great , levels increased within a week & could definitely feel the increase in energy , almost too much energy after 2 weeks on it, so I reduced my dose to every 3rd day
Love the Boost 3 & Ultimate 4 mixed together, it’s so refreshing. I look forward to it every day. I’m yet to see noticeable results of the Trx yet, but it’s only been a few weeks.
I’ve tried plenty of supplements over the years, but this is honestly the best I’ve taken!
I took it to Europe with me & noticed a difference almost immediately. I had more energy, felt amazing & didn’t get sick once during the trip.
When I got home, I ran out while waiting for my next order. After five days without it, I could really notice the difference in how I felt. I’m back on it now & so impressed I’m getting the whole family started!
Cannot recommend it enough. Six stars if I could!
Taking the ultimate 4 and boost 3 and have never felt better. Loads of energy and i have had no coldsore outbreaks at all. Hubby 's blood pressure has improved and has also noticed more energy 100% recommend these products
My husband and I are 70 and 64 respectively and whilst we are still building our NO levels due to our age and other health factors we are thrilled to be experiencing a great improvement in our energy levels. No longer hitting a brick wall mid afternoon is just fantastic. We feel we are getting the opportunity to age better!
Love it - definitely feeling more energised. Cant seem to get a good reading on the nitric test strips but I do feel better. I think i may need to add the boost to complement on my next order
My name is Sheryl Ogston I am 75 years old, my daughter Rochelle gave me the ultimate 4 and boost 3 for my birthday, I have been talking it for a month now. I am feeling great, more energy, brain fog better, just feeling better all round and my nitric oxide levels are up to 110mg/L. I have been telling everyone I know to get onto it. Thanks Jeff for such great products.
So far one tub and energy more consistent. Took overseas whilst conquering the streets of Japan! Definitely needed! Purchased my second tub and will test more with this one to check NO levels
I noticed a difference in my energy levels & the flow on effect was my mood, within days of starting this. I can’t wait to see the long term effects it has.
2nd tub just started and enjoying the taste and easy of mixing the drink of a morning.
Starting to feel my energy increasing. Sleeping better and not needing to hit the snooze button on my alarm 😄
Following Jeff's recommendations with diet and exercise and looking forward to feeling fantastic again
Whilst it is too early to show an increase in my nitric oxide readings as I’ve only been taking this product for a few weeks, I definitely have more energy and improved brain function.
I was taking the women’s bundle for a month. Felt the benefits almost immediately. Unfortunately due to postage, my recent order got lost. I didn’t have anything for 3 weeks. Extremely disappointed, but I just had to be patient. My order finally arrived a few days ago and hands down, the best feeling! I actually think in hindsight the few weeks without these amazing products actually proved to me how good they really are. I Feel AMAZING! Thank you Jeff…. Long may this last🙏🏻

Many women notice steadier energy in the first two weeks. Hormone and body-composition changes build over 8 to 12 weeks, which is why the reset runs for 90 days.
The bundle is designed to sit alongside HRT. TRx is a botanical serum, not hormone replacement. If you take prescription medication, check with your healthcare provider first.

This depends on the type of fast and your goal. Most people actually practice time-restricted eating rather than true fasting. Any food restriction under 24 hours is time-restricted eating. The benefits of fasting beyond 24 to 72 hours come from autophagy, and the products will break this process. Beyond 72 hours this effect is reduced and it is advisable to take the products to support the detoxification process. Under 24 hours you can take the products as normal.
