Pain Relief Doesn't Have to Be a Pill
Premium topical pain relief. Originally formulated for the Boston Red Sox. Designed, formulated, and managed from Los Angeles.
The Origin
It started with a formula originally developed for the Boston Red Sox. A prescription-strength topical NSAID designed for professional athletes who needed fast, targeted pain relief without the systemic side effects of oral medication.
That formula became the foundation of Ketro. We built a company around a simple idea: pain relief doesn’t have to be a pill. Topical means targeted — medication goes where you need it, not through your entire body. Your liver never sees it. Your stomach never knows.
We took that clinical-grade formula and paired it with a premium daily magnesium cream — skincare-level formulation, not drugstore. Two products. One philosophy. Pain relief that works where it matters, formulated to a standard that didn’t exist in this category.

Frequently Asked Questions
What is Ketro?
+Ketro is a premium topical pain relief company based in Los Angeles. Two products: RX Pain Gel (prescription-strength ketorolac, a topical NSAID) and CALM Magnesium Cream (OTC daily topical magnesium). Both are designed to deliver pain relief directly through the skin — targeted, not systemic.
How is topical pain relief different from pills?
+Topical pain relief is applied directly to the skin over the pain site. It absorbs through the dermal layers to reach underlying muscle, joint, and connective tissue. Because it bypasses the GI tract and systemic circulation, systemic absorption is 5-17x lower compared to oral painkillers — meaning significantly reduced exposure to organs unrelated to the pain source.
Do I need a prescription?
+RX Pain Gel requires a prescription, which is included with your purchase. After you order, a licensed physician reviews your health questionnaire and approves the prescription. The gel is then compounded and shipped directly to you. CALM Magnesium Cream is over-the-counter — no prescription needed.
Where are your products made?
+RX Pain Gel is compounded per order in a licensed US pharmacy (Precision Compounding Pharmacy). CALM Magnesium Cream is manufactured with premium ingredients and ships from the United States.
