This product worked!!

Verified Customer

I've had a discolored toe nail for years, and been to two podiatrist who sent a piece of my nail for testing and it came back as a toe nail fungus (can't really remember the name) my options were an oral medication, removal, or laser (which is quite expensive) One of my veteran friends recommended that I try Treatonic, so I decided to give it a chance. I've been using this product consistently for a few weeks and already noticed a drastic difference. I know that it will take awhile for it to be completely healed, but I know for a fact that this works and I will continue to use until completely healed.

Frequently asked

How long does it take to see results?
It depends on your nail and the severity of the infection. A toenail grows out fully over 6–12 months, so visible change is gradual as healthy nail replaces damaged nail. Consistency matters far more than speed — which is exactly why we offer 100 days to try it.
How many nails does one kit cover?
Each kit contains 3 Day Pens + 32 Overnight Patches. Typical use is a daily pen application plus nightly patch across 3–5 affected nails. For a full multi-month protocol, most customers choose the 2-Kit or Full Protocol option.
Will the overnight patch stay on while I sleep?
Yes. The patch is designed with a skin-friendly adhesive that wraps and seals around the nail. Press the edges firmly when applying for the most secure fit through the night.
Can I use Treatonic if I have diabetes or other conditions?
If you have diabetes, peripheral vascular disease, or any underlying condition, please consult your healthcare professional before starting any new nail treatment protocol.
Why 25% Undecylenic Acid? Why not a lower concentration?
25% is the maximum concentration permitted for Undecylenic Acid under the FDA OTC monograph. It's topical only, so there's no systemic absorption and no liver-function monitoring as with oral antifungals.
Do I need to throw out my shoes?
No. The overnight patch is designed to physically contain shedding so there's less material reaching your shared surfaces. Routine hygiene — clean, dry socks and letting shoes air out — is good practice alongside the protocol.
What if I don't see results within 100 days?
Contact us for a full refund — no return shipping required. We built the 100-Day guarantee specifically because nail care takes time and we want you to be able to give it a fair trial risk-free.
Is this a subscription? Will I be re-billed?
No. Every option here is a one-time purchase. You will not be enrolled in any subscription or re-billed automatically.
