Your 180-day journey to lasting confidence
The formula in Endurance Catalyst was studied over 12 weeks — not days. Here's what a consistent daily routine looks like over six months, and what the research reported on the individual ingredients has found.
Day 1
Your daily ritual begins
Two capsules with water, once a day — morning or night, with or without food. 100% natural and prescription-free. The routine starts here.
Day 14
Consistency takes hold
By week two, your daily serving — selenium, vitamin D3, zinc, vitamin B6, black aged garlic and ginger — is part of your rhythm. Consistency is exactly what the research is built on.
Day 30
One month in — building the base
Your first pot is done. These nutrients are designed to be taken consistently over time, so the early weeks are about building the foundation, not reaching the finish line.
Day 90
The 12-week research mark
This is the point mirrored in the clinical study on the formula. Here's what participants reported after 12 weeks:
68%
reported increase in overall sexual satisfaction (12-week study)¹
70%
reported decrease in stress and anxiety around sex¹
Day 180
Six months of daily support
You've built a habit that lasts. After six months, daily support for endurance and confidence is simply part of your routine.
12-week

Everything about the formula, taking it, shipping and the guarantee — honestly answered.
Endurance Catalyst is a 100% natural daily supplement for men who want to support sexual wellbeing, endurance and confidence. It combines six evidence-based nutrients — selenium, vitamin D3, zinc, vitamin B6, black aged garlic and ginger — in one formula. It is designed for adults looking for a natural, prescription-free option to support everyday stamina and confidence. Food supplements are not a substitute for a varied, balanced diet and a healthy lifestyle.
Take 2 capsules once a day with water, morning or night, with or without food. One bottle contains 60 capsules — a full 30-day supply. Do not exceed the recommended daily intake.
This works with consistency, not overnight. The clinical study on the formula ran over 12 weeks, so plan for continuous daily use over several weeks to months. Many users report positive changes within the first few weeks; individual results vary and reassess from there. Individual results vary.
The capsule shell is vegetarian HPMC. The formula contains soy bean (beta-sitosterol and soy isoflavones), so it is not suitable for people with a soy allergy. As a natural supplement it has a low risk of side effects, but individual reactions can vary and it is free from artificial colours and preservatives.
If you take any medication or are under medical supervision, consult your doctor before use. This is especially important if you take antidepressants (SSRIs) or blood-thinning medication. When in doubt, a quick check with your doctor or pharmacist is always the safest route.
Everything is on the label: beta-sitosterol, pumpkin seed extract, zinc, soy isoflavones, lycopene, saw palmetto, vitamin D3, selenium, garlic bulb extract, vitamin B6 and ginger — with no hidden proprietary blends. Every batch is lab-tested. You can view the complete supplement facts on the product page.
