BOOST

The TRx Serum delivers natural botanical and nutritional extracts through the skin via transdermal absorption, supporting the body's own testosterone signalling pathways without synthetic hormones. Both the men's and women's versions use the same transdermal delivery method, calibrated to the different physiological needs of each.

In men, testosterone supports energy, drive, muscle tone, mood, libido, and metabolic health, with levels declining gradually from the mid-30s onwards. In women, testosterone is produced by the ovaries and adrenal glands and plays an equally important role in energy, libido, bone density, muscle tone, and cognitive function, with decline beginning from around age 30. Both versions of the serum are designed to support these functions naturally as part of a consistent daily routine.

Apply each morning as directed. Men apply 3 pumps to the inner arms, and optionally to the testicles where skin permeability supports efficient absorption. Women apply to the inner arms or wrists where skin is thinner. Wipe any remaining serum into the skin before dressing. Morning application aligns with the body's natural hormonal rhythm and is the recommended timing for both.

The serum works as a standalone product for both men and women. For men, using it alongside Men's PLUS provides dual-pathway support through both topical and oral delivery, which is the approach Jeff Butterworth recommends as part of the Testosterone Reset protocol. For women, it complements the Health Optimisation Program and broader hormonal health routine. Neither pairing is required, but both are designed to work together.

Best assessed over 8 to 12 weeks of consistent daily use. Some users notice early shifts in energy and mood within the first few weeks. We recommend a baseline blood test before starting and a retest at 30 to 60 days so you have objective data rather than relying on feel alone.

No. Both formulations contain only natural botanical extracts. Neither is a form of hormone replacement therapy and neither introduces exogenous hormones into the body. They work with your biology, not in place of it.

Yes. Both formulations are designed for ongoing daily use. If you are pregnant, breastfeeding, on prescription medication, using HRT or the oral contraceptive pill, or managing a diagnosed hormonal condition, speak with your healthcare professional before starting.

Ultimate Cardio+ is formulated to support your body's natural nitric oxide production, a key molecule involved in healthy circulation and vascular function. Nitric oxide plays an important role in supporting blood vessel flexibility and cardiovascular wellbeing. Whether you're focused on maintaining heart health as you age or want to support your circulatory system proactively, Ultimate Cardio+ provides targeted daily nutritional support.

Most users experience no side effects when using this product as directed. It is well tolerated in general use. As with any supplement that supports cardiovascular function, we recommend speaking with your healthcare professional before use, particularly if you are currently under medical supervision.

If you are currently taking prescribed medications, we recommend discussing supplementation with your healthcare professional before starting. They can monitor your progress and advise on what is appropriate for your individual circumstances.

The duration depends on usage frequency and the specific product. Most customers find that one bottle lasts 30-60 days with regular daily use. Check the product label for the recommended serving size and quantity per container. We offer subscription options for convenient recurring deliveries.

Most men begin noticing improved energy, focus, or motivation within a few weeks, but lasting balance takes time. Men’s PLUS supports your natural hormonal rhythm, so steady progress over 8–12 weeks is typical. We encourage you to do a testosterone test before starting and at either 30 or 60 days. We see levels optimising within the first 30 days. How long you need to continue at 2 capsules per day depends on your levels optimising and stabilising. Once stabilised then you can reduce to 1 capsule per day as a maintenance dose.

Men’s PLUS is formulated to be gentle, but if you take prescription medication, it’s best to check with your healthcare provider first. Our formulas are designed to complement, not replace, medical care.

It doesn’t artificially raise testosterone. Instead, it supports the body’s own hormonal pathways, helping restore rhythm and sensitivity for natural balance and energy. The amazing thing with Men's Plus is it optimises, yet doesn't excessively boost levels above optimal ranges like synthetic testosterone which causes many of the side effects.

Yes. The nutrients and herbs are designed for ongoing support. This is why however we suggest regular testing when starting to show levels being optimised and then maintained. Once maintained you can reduce the dosage. Many men use it daily to maintain consistent vitality and mood.

Morning with food works best. This aligns with your body’s natural hormone rhythm and helps absorption of key nutrients. Testosterone levels are at their peak in the morning so it makes sense to have your dose then.

Actually all 3 products have been designed to take together as a system to give you everything you need as a man. If finances are an issues, then the men's plus will achieve your goal of feeling better and boosting your testoterone levels. If you want to optimise your health, then the boost provides another whole level of metabolic health which is a key component of your body producing optimal hormone levels, not just testosterone. The best results we see are when Boost is added to the daily stack.

Relief often begins within a few weeks, though steady improvements in flow and frequency usually develop over 4–8 weeks of consistent use. It does however depend on the size of your prostate when starting. The larger it is, the longer it takes. If frequency is a big issue for you that needs resolving fast then you could add Happy Bladder from my sister company, Happy Healthy YOU which is specific for urinary frequency and urgency.

Yes. The formulas are designed to complement each other safely. Prostate PLUS targets urinary comfort and inflammation, while Men’s PLUS and BOOST support hormonal and metabolic balance.

Yes. It does this by correcting your hormonal cascade and reducing the amount of Di Hydro Testosterone which is the primary driver of prostate enlargement. Of course the larger your prostate, the longer this can take. Prostate plus also reduces inflammation and supports healthy function, which can improve flow and comfort.

Yes, in most cases. However, we recommend confirming with your healthcare provider before adding any supplements post-surgery. We would suggest also adding the Men's Plus and Boost to optimise your overall male health which is more than likely compromised if you have had to have prostate surgery.

Consistent use delivers the best results. The nutrients and plant extracts are designed for gentle, ongoing support.

The best results come from taking all 3 products. It is a system and designed to provide 90% of what men need as we age. If finances are a concern then prostate plus will work alone, however if you have the resources your body will benefit from all 3 products and you will feel the improvements across your whole health.

BOOST offers dense nutrition but isn’t a full multivitamin. It’s best seen as your daily nutrient foundation — supporting energy, immunity, and focus. Personally I have not taken a mulitvitamin for years because I prefer to get my nutrition from superfoods that are contained in BOOST.

Yes, but it will not taste great. Also many men find they need less caffeine once BOOST becomes part of their morning routine. Its adaptogens support steady energy without jitters. The preferred method of taking the BOOST is in 500ml to 1 litre and sipped on across the morning. This gives a slow feed of nutrition and optimises your metabolic health.

Mix one scoop into water, juice, or a smoothie. Take it daily, consistency builds results through nutrient repletion and adaptogenic balance. Add the prostate plus if you have it and drink together. We suggest to slowly sip on it through the morning, however it can be taken all at one time.

Yes, it’s safe for both men and women. While formulated for men’s needs, the ingredients support general vitality and resilience. Many women take BOOST for the heart and circulatory benefits as well as brain health.

BOOST has a natural flavour with mild herbal notes, a reflection of its real-food ingredients and medicinal mushrooms. People comment they really enjoy the taste and adds a nice complement to your morning routine. It certainly is not a bad taste.

Place a drop of saliva on the test pad, wait 10–20 seconds, then compare the colour to the chart provided.

A deeper pink colour indicates higher nitric oxide levels, showing good vascular and metabolic function. A lighter shade suggests your levels may need support through diet or lifestyle changes.

Once or twice a week gives a good picture of your baseline and progress. You can test more frequently when starting a new supplement or lifestyle change.

Yes — foods high in nitrates (like beetroot, spinach, or rocket) can raise readings. That’s part of how nitric oxide–supporting diets work.

Morning testing gives the most consistent results, before eating or brushing teeth.

Yes all our products are vegetarian and the capsules are vegecaps.

This depends on the type of fast and your goal. Most people actually do not fast. They time restrict eat. Any food restriction less than 24 hours is time restricted eating rather than fasting. The benefits of fasting beyond 24 to 72 hours comes from autophagy. The products will break this process. Beyond 72 hours this effect is reduced and it is advisable to have the products to support the detoxification process. Before 24 hours you can take the products.

We currently ship globally. Our goal is to build an international community of healthy and vital people. We have capped shipping costs to make it more affordable.

Most orders arrive within 3–7 business days, depending on location. Remote areas may take slightly longer.

Yes. You’ll receive a tracking link by email once your order ships.

If your parcel doesn’t arrive within the expected window, contact our support team and we’ll track it down. You can also add a small shipping insurance at checkout in the small chance it does not arrive.

If the product is faulty in any way we will refund you. We do not refund based on change of mind, a doctors opinion or lack of results. We know the products work very well and in the rare chance it does not then usually there is something else you have done to stop it working such as inconsistent dosage, excessive alcohol intake or medications blocking the products working.

Just like you would not ask for a refund from a doctor, we work on the same premise. That being said, if you are not happy, reach out to us and lets have a conversation about why it may not be working and in most cases we can identify why for you so you can get the same great results as all the other men.

For safety reasons, we can’t accept opened products unless there’s a quality issue.

Contact our customer support team with your order number. We will set up a chat to see what is happening and how we can help.
