GymBrobot
AI COACH · HUMAN EXPERTS BEHIND HIM

Sees the whole you.Answers the whole question.

The sharpest gym bro you’ve ever had, across peptides, protocols, bloodwork and training. Most AI deflects the moment you ask something real. GymBro won’t. You get the research, what thousands of people running the same protocol actually report, and a straight answer on which is which. And a real physician or researcher whenever you want one.

You

Just got labs back. LDL-C is normal but coach flagged ApoB at 118 — do I actually need to care?

GymBrobot

Yes — ApoB counts the particles that actually build plaque, and 118 puts you above the optimal band even with LDL-C looking fine. Fiber, omega-3s, and a recheck in 12 weeks is the move. Want the full protocol?

You

Give me the protocol. And can I keep creatine in?

What it covers

Four expert fields. One picture of you.

Each domain is trained with experts in that field — and the coach connects them, so advice about your stack knows about your labs, and your programming knows about your recovery.

FIT

Fitness

Periodized programming built on volume landmarks, recovery, and your actual lifts — not influencer splits. Form breakdowns, strength-curve modeling that flags a stall before it happens, and conditioning that treats VO2 max, work capacity, and zone-2 endurance as numbers you train, not afterthoughts.

Exercise science
PEPT

Peptides

Protocols explained straight — dosing, timing, stacking, and cycle design across recovery, growth, and metabolic compounds. What’s studied, what’s speculative, what’s genuine risk, and how to read sourcing and quality before you run anything.

Pharmacology research
NUTR

Nutrition

Macros and micros mapped to your goal and your training load, protein that holds muscle through a cut, and meal timing that fits your day. Supplements only where they earn it — creatine, electrolytes, the handful with real evidence — and a straight answer on the rest.

Nutrition science
LABS

Bloodwork

Paste your panel and GymBrobot helps you understand which numbers actually need attention — across hormones, thyroid, lipids, and metabolic and inflammatory markers — tracked as a trend over time, not a single snapshot. It explains what’s drifting and ties it back to the training, nutrition, and peptides that move it.

Lab medicine

The best gym bro in the world has watched every video, read every study, and remembers everything you’ve told him. He’ll go further than any other AI will — because a real professional is already standing behind him.

Where the gym bro taps out

Even the best gym bro is still just a gym bro. Yours has a team of qualified experts behind him.

Your GymBro handles most of what you’ll ask — instantly, from the research, not forum lore. Some questions are above any gym bro’s pay grade: a protocol that needs a clinician, a lab panel that changes the plan, a call where the evidence is still forming. Those go to human experts, and you can call one in yourself, any time.

FDA peptide advisory panel

Designs peptide and hormone protocols and trains the providers who run them. Came up in oncology research — CAR-T cell therapy trials at UChicago Medicine — and sat on the FDA advisory panel that reviewed peptides. Reads the real-world protocol data, not just the published literature.

Board-certified · obesity & lifestyle medicine

Board-certified in family, obesity, and lifestyle medicine, and licensed to prescribe across fourteen states. Founded a longevity clinic and a food-as-medicine kitchen. The conservative check — what’s safe, defensible, and worth standing behind.

One team. The right specialist for your question.

They work together behind the coach — but you’re not booking a committee. You reach the one your question actually needs: the trainer for a program, the researcher for a protocol, the physician for anything clinical. Most questions need one. Book more only if you want to.

How the experts work

Reach for an expert on your terms.

Your GymBro answers by default. When you want a human, pull one in — and pay only for what you use.

  1. Included

    Ask GymBro

    Instant answers, all day. The default — grounded in the research, remembering your whole history.

  2. Per question

    Route it to an expert

    Route the question to the trainer, researcher, or physician. It lands in their queue with your full conversation attached, and they reply when they can — usually in 4–24 hours. Their answer drops into your chat. You pay that expert's price for that one question — nothing more.

  3. Booked

    Book their time

    Want more than a message? Book a 15- or 30-minute consult — video or phone — with the expert who fits the question.

Pay-as-you-go. Pay per question or per consult, at each expert’s own rate — no membership, no wallet to top up.

GymBro never prescribes. Anything involving a prescription is a proper telehealth visit with the physician — and never pretends otherwise.

15 questions a day, every day, with the full feature set. No trial countdown, no card required.

Can I cancel?

Anytime, straight from the Stripe billing portal in your account. Pro stays active through the end of the period you already paid for.
