The problem
What the years take from you without warning
After 30, testosterone drops by about 1% a year.* And it isn’t just age: chronic stress, poor sleep, processed food and sitting all day push the same way.
You feel it everywhere: less energy in the afternoon, less drive, more belly fat, slower recovery. And in the bedroom, where circulation matters as much as hormones.
It doesn’t have to be that way. ONYX exists to give your body what it needs to do its job.*
Illustrative curve. *Between 0.8% and 1.6% a year depending on the method, in the Massachusetts Male Aging Study (Feldman et al., J Clin Endocrinol Metab, 2002).

Questions
What people ask us
Which one is for me?
If you're after energy, stamina and firmness, start with NITRO. If your issue is fatigue, low desire or stress, TESTO. If you're concerned about circulation, cholesterol or your heart, NATTO. Many men combine two or all three.
Can I take them together?
Yes. They're designed to work together: TESTO supports your hormones, NITRO your blood flow and NATTO your arteries. If you take blood thinners, blood pressure medication or erectile dysfunction medication, ask your doctor first.
When will I notice something?
It depends on the formula and on each body. With NITRO, many notice more energy within days; with TESTO, within 2 to 3 weeks; with NATTO, circulation usually changes between weeks 3 and 5. The full effect builds over 90 days of consistent use.
Is shipping discreet?
Yes. It arrives in a plain box, with no logo or product name on the outside. We ship throughout Chile.
What if it doesn't work for me?
You have a 30-day guarantee. If you're not satisfied, write to us and we'll refund your money.
