Thermo-XY®: Take 1-2 servings per day with water, preferably on an empty stomach. To assess tolerance, start with 1 capsule, which is half a serving. Do not take within 4 hours of bedtime.

Test-FX®: On training days, take one serving of 5 capsules with water around 1 hour before working out. On non-training days, take one serving of 5 capsules with water before bed. Can be taken with or without food.

Suggested stack routine: Use Thermo-XY® earlier in the day to support your fat-loss and training routine, then use Test-FX® according to whether it is a training or non-training day.

The Men's Physique Stack: Sculpt Your Ultimate Body

Introducing the DNA Lean Men's Physique Stack, a synergystic combination of Thermo-XY, our premium fat burner, and Test-FX, our best-selling hormone support for men. 

Crafted for the man on a mission, this stack goes beyond conventional supplement stacks. 

Thermo-XY is your secret weapon for effective fat loss, supporting a healthy metabolism and powerful fat oxidation, helping you to reveal those gains that you've worked so hard for.

Pair that with Test-FX, properly formulated to help optimise testosterone levels, supporting your peak performance, muscle mass, and definition. 

Sculpt your dream physique with the DNA Lean Men's Stack, where science meets nutrition for exceptional results.

The Men’s Physique Stack is best suited to men who want to support body composition, training drive and male vitality together - rather than treating fat-loss and testosterone support as separate goals.

It may be ideal if you are in a cutting phase, trying to reduce body fat, or want extra support for energy, focus and gym consistency while maintaining your masculine edge.

Thermo-XY® supports your daytime fat-loss and training routine, while Test-FX® supports healthy testosterone levels, vitality, drive and performance.

This stack is not designed as a shortcut - it works best alongside structured training, consistent nutrition, sleep and recovery.

Order before 2pm on a working day and we’ll aim to dispatch your order the same day.

Enjoy free 48-hour shipping over £50 or free 24-hour shipping over £90.

Why the Men’s Physique Stack is Different

Most physique-focused stacks treat fat-loss, training output and male vitality as separate goals. The Men’s Physique Stack was built to support them together.

Thermo-XY® supports your daytime fat-loss routine, energy, focus and training intensity, while Test-FX® supports healthy testosterone levels, drive, vitality and performance.

That matters because body composition and male hormonal health are closely linked. Excess body fat can negatively influence testosterone balance, while low drive and poor training consistency can make fat-loss harder to sustain.

No random bundle. No single-angle shortcut. Just a targeted two-product stack built for men who want to cut, train hard and support their masculine edge at the same time.

Frequently Asked Questions

Thermo-XY is stimulant-led, so sensitive users may feel more alert. While this is perfectly normal, we suggest that you avoid taking it late in the evening, and monitor additional caffeine from coffee, pre-workout and energy drinks. EFSA states single caffeine doses up to 200mg are generally safe for healthy adults.

No fat burner can “spot reduce” belly fat, but Thermo-XY can support the conditions that help reduce overall body fat: higher energy output, better training intensity and improved consistency.

The energy effect can be felt the same day, often within an hour, depending on your stimulation tolerance. Body composition changes usually need consistent use, diet and training over several weeks.

Usually, it’s better not to stack it with extra stimulants until you know your tolerance. If using coffee or pre-workout, keep total caffeine sensible and avoid combining multiple high-stim products.

Test-FX is designed for daily use when taken as directed. Aside from any hormonal benefits, Test-FX contains essential ingredients that the body requires on a daily basis which are consequentially considered crucial for your health.  Therefore Test-FX is perfectly safe to be consumed every day.

No. Test-FX is a natural testosterone support supplement using plant extracts, vitamins and minerals to support healthy male physiology.

Some men notice better drive, mood or training motivation within a few weeks, but the best results usually come from consistent daily use over 4–12 weeks. For example, Ashwagandha trials commonly run for around 8-12 weeks.

If your levels are already within a normal range, do not expect steroid-like changes. Test-FX is designed to support healthy testosterone, stress resilience, recovery and general male wellbeing, by providing the body with key essential ingredients required for optimal hormone synthesis.

Test-FX is not built on hype or mega-dose mystery blends. It combines branded, evidence-led ingredients with key minerals and vitamins linked to normal testosterone production, muscle function and wellbeing. In addition, every ingredient is effectively dosed, which is why each serving is 5 capsules.

This can vary significantly from product to product. Test-FX is designed to support stress, sleep, nutrient status and training recovery. Test-FX uses ingredients such as KSM-66® ashwagandha, fenugreek, ZMA, vitamin D3 and selenium to support male performance naturally. Well-documented human studies show these ingredients are most effective at supporting healthy testosterone in men.
