Full Stack Pharmaceutical Company for Personalized Peptides and GLP-1s

RonanRX is a full-stack pharmaceutical company, starting with personalized peptides and GLP-1s. In our first 10 weeks, we went from having no pharmacy to being licensed in 33 states. Since launch, we’ve grown 50% week over week. We manufacture the medications ourselves, sell directly to patients, and eliminate the layers of middlemen that make prescription drugs more expensive. What makes this possible is AI. Traditional pharmaceutical companies are built to manufacture one drug for millions of people. RonanRX is purpose-built to personalize treatment for each patient: different biology, different response, different dose. Patients come directly to RonanRX or through doctors using our platform. Every patient completes our medical intake, meets with a licensed doctor through our telehealth platform, and receives a personalized prescription when appropriate. From there, we manufacture the medication ourselves and deliver it directly to the patient. Labs, wearables, medical history, treatment response, and other health data feed back into the platform so doctors can continuously refine treatment over time. Before AI, doing this for every patient at scale was impossible. We didn't invent the demand we are seeing. 80 Million people are on a GLP-1 and millions more are using Peptides. We're building a better way to manufacture, personalize, prescribe, and deliver them. Our founders have built and exited multiple companies, raised more than $100M, built a $50M U.S. medical manufacturing business, and spent years developing peptide therapeutics at companies including Eli Lilly and AbbVie. We’re just getting started with peptides and GLP-1s. Next comes hormone therapy and the rest of personalized medicine.

Company Launches

RonanRX: We use AI to personalize peptides to your biology

See original launch post

Peptides are like Claude Code for your body. Your biology is the prompt.

TL;DR: RonanRx personalizes GLP-1s like Ozempic and other peptides to your biology, because you are not average. Connect your lab results, wearable data, and medical history once. Our HIPPA compliant Al turns them into a plan which a licensed doctor prescribes, adjusts every cycle, and ships to your door. Start with a text at RonanRx.com.

Big Pharma Makes 1 Drug for Millions.

Peptides are the most personalizable medicine we have, and everyone has different biology. GLP-1s like Ozempic help you lose weight. Others help you recover faster, sleep better, live longer. Telemedicine often prescribes them like a vending machine: fill out a quiz, a doctor you’ll never meet rubber-stamps it, and you get the same molecule at the same dose as everyone else. Nobody reads your data and adjusts when your body responds differently than the “average patient.” That’s not medicine, it’s a spreadsheet.

How RonanRx works

Connect your health data once, and we run the complete feedback loop for personalized medicine:

Your biology in one place. We sync your labs, wearables, medical history, and treatment response into a single health profile.
AI turns data into a plan. It reads how you are responding and proposes the next move: dose, formulation, what to add.
A real doctor decides. Every prescription is made and adjusted by doctor looking at the same data you are. The AI proposes, the doctor prescribes.
Delivered to your door, and every outcome improves your next protocol.

Instead of treating the average patient, we personalize your treatment continuously as your body changes.
