The Ritual

Understanding your body’s rhythms is key to long-term hormonal balance. Review your full lifestyle, when you eat, sleep, train, and relax.

For optimal testosterone support, it’s important to manage stress, get quality sleep, and fuel your body with the right nutrients, day and night.

Optitest PM: 3 capsules 1-2 hours before bed.

Prefer not to swallow capsules? Open them, pour into a smoothie and blend. Drink immediately.

The Science

Zinc contributes to the maintenance of normal testosterone levels in the blood, normal fertility and reproduction, normal cognitive function, and normal acid-base metabolism.

Magnesium contributes to a reduction of tiredness and fatigue, normal muscle function, normal psychological function, and energy-yielding metabolism. Vitamin D contributes to the normal function of the immune system and normal blood calcium levels.

The split formula means no energising compounds at night and no relaxing botanicals during the day, each blend works with your natural rhythm.

Notes from the field

What people actually say.

  • After two weeks of using Optitest, I noticed a boost in mood, energy, and strength. I feel more motivated and confident, my workouts feel stronger, and my endurance has improved. The formula works well with no side effects and has exceeded my expectations.

    Mohammed Qasim

  • Optitest has boosted my testosterone. I feel more energy, strength, and better overall well-being. My blood work confirms the change, and I notice the difference daily. My sleep is deeper, more restful, and I wake up recharged each morning. This formula works great.

    Sahl Mohammed

  • Optitest made a clear difference in my energy and sleep. I feel more energised during the day and sleep deeper at night. It’s great having everything in one supplement without worrying about low doses. The ingredients are timed right, and the formula works very well.

    David Palushi

  • I’ve added Optitest to my routine recently and appreciate the variety of natural ingredients and the thought that’s gone into it. Yusif Mash is someone I value when it comes to health and performance, and it’s great to see him making products aligned with his philosophy.

01What is Optitest and who is it for?

FUNCTNL Optitest is a day & night performance system designed to support natural testosterone levels, energy, strength, recovery, libido, and sleep quality. It’s built for men who train, perform, and want to operate at a higher baseline physically and mentally.

02How does Optitest work?

Optitest uses a split AM + PM formula to support performance when you need it and recovery when it matters most. The daytime blend focuses on energy, strength, stamina, and hormone support, while the night-time blend supports relaxation, sleep quality, and hormonal recovery, working with your body’s natural rhythms.

03What is the Optitest ritual?

Take Optitest AM, 3 capsules after breakfast, to support daytime performance and energy. Take Optitest PM, 3 capsules 1-2 hours before bed, to support relaxation, sleep quality, and overnight recovery. This day-night approach helps support performance without overstimulation.

04What are the key ingredients and why are they used?

Optitest combines clinically respected and ancestrally used ingredients, including:

  • Zinc bisglycinate to support testosterone production and immune function
  • Tongkat Ali and Fadogia agrestis to support strength, energy, and athletic performance
  • Shilajit to support stamina, recovery, and nutrient absorption
  • Ashwagandha KSM-66® to help manage stress and support hormone balance
  • Passion flower and lavender to support relaxation, sleep quality, and night-time recovery

Together, they form a functional system rather than a single-path testosterone product.

05Can I take Optitest every day?

Yes. Optitest is designed for daily use as part of an active lifestyle. Consistent use supports cumulative benefits across energy, performance, recovery, and sleep rather than short-term stimulation.

06Is Optitest suitable for everyone?

Optitest is formulated for active adult men. If you are under 18, have a medical condition, are taking medication, or have concerns around hormone health, consult a healthcare professional before use.
