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
Our founder had really bad TMJ. Her dentist told her to walk into a drugstore and pick up a topical pain gel — something she didn’t realize even existed. Medication that works at the source instead of running through her whole body.
What was on the shelf was the problem. Tubes that smelled like menthol and Vicks. Greasy formulas in packaging that hadn’t been updated since 1985. Nothing she’d want to put on her body, let alone her face. Modern medicine had quietly skipped the topical pain aisle.
Pills weren’t an option either. A sensitive stomach ruled out oral pain medication, and ruled out magnesium pills along with it. So she went looking for a magnesium cream. Same problem, different shelf: chalky, oily, medicinal, or coded as crunchy wellness. Functional, maybe. Pleasant, no.
Ketro was built to do better on both shelves. A prescription-strength topical NSAID — the same formulation originally developed for the Boston Red Sox — paired with a daily magnesium cream that absorbs like a serum. Pharmacy-grade where the category was drugstore. Skincare-formulated where the category was crunchy. Pain relief, applied where it hurts. Pain relief that doesn’t have to be a pill.

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.
