The complete synergy for your testosterone.
At a given age, men today have on average lower testosterone than previous generations. GOL brings together nine actives, including Shilajit, Zinc and Ashwagandha, in a formula built to support your testosterone and vitality. Made in France.
The reality
At a given age, men today have on average lower testosterone than their elders, an underlying decline observed by research since the 2000s. Stress, sleep, diet, sedentary life: the modern lifestyle weighs heavy. GOL is built to help you take back control.

What the science says
Every active in GOL is there for a reason, backed by research. Here are the sources, freely accessible. Click, verify.
At the same age, men today show on average lower testosterone levels than previous generations. This underlying decline, independent of ageing, has been documented by research since the 2000s. It is what guided the design of GOL.

The team
Founders
A licensed pharmacist who signs the formula, an engineer who runs the product, a sales lead who works with doctors. Real names, real faces, real accountability for what goes in the capsule.
PharmacistCofounder, licensed pharmacist
Owner of an independent pharmacy in Chartres, France. He reviewed and pushed back on every ingredient, every dose and every claim in the GOL formula. Nothing ships without his pharmaceutical sign-off.
Cofounder, product and operations
Engineer, former data lead at Chanel and Hermès. Runs the formulation work with the Phytolor lab, the website and the supply chain. Makes sure the doses on the box are the actual doses in the capsules.
Cofounder, distribution and field
Owns the sales side and the relationship with prescribing physicians. Years working with doctors and pharmacies on the ground, not from slides.
It started with a simple observation: the men's supplement aisle is a minefield. Promises of transformation in two weeks, labels that hide their doses behind a proprietary blend, faceless brands made who-knows-where. With Ryan, a licensed pharmacist, we took the problem from the other end. We started from the only actives with a recognised health claim in Europe (zinc, magnesium, vitamin D), dosed them seriously, and added traditional plants men have talked about for centuries. Our only rule: everything in the capsule is written on the box, down to the milligram. Made in France, approved by a pharmacist, sold with no magic promise. That's GOL.
Our cures
The hormonal cycle plays out over 90 days, which is why the 3-month cure is our default recommendation. The 1-month cure stays useful for a trial, the 6-month cure for those who want to settle into the protocol.
