Why we built
YOD.
Longevity medicine has, for the most part, become very loud. Stacks, "protocols," subscriptions, research-peptide forums, monthly drops, and influencer doctors. We wanted to build the quiet version. A real clinic, a real chart, a real clinician, on a real cadence. Members for the next twenty years, not customers for the next thirty days.
We're not your gym.
We're not your spa.
We're your clinic.
Cold plunge, sauna, hyperbaric, cryotherapy — those are wonderful, and we send Signature members to Othership, Higher Dose, and Bathhouse at preferred rates. YOD is none of those things. YOD operates the medicine. Bloodwork, peptides, hormones, IV therapy, body composition, the protocol. The rest of your life happens elsewhere.
The product is the practice — not the perk stack. Every member begins with seventy-three markers and a ninety-minute sit-down. Every member returns every quarter for a re-draw and a written letter. Every prescribed compound either ships to their door or is administered in our suite — they choose, per Rx, and can switch any time.
The medicine is at honest member rate, transparent to the market — never to the wholesale. The membership is the relationship. The clinic is the experience.
Two people who built it.
Nathaniel Gartenberg.
Builds the product, operates the business. Background in technology, behind the scenes by preference; not the public "face." Year-one founder salary deferred — same number as Coby's.
Coby.
Head of Member Experience & Culture. Best friend, investor relations point, brings the network. Owns the member journey end-to-end — the in-clinic ritual, the welcome experience, events, the small details that make luxury feel real.
A short timeline.
Diagnosis.
Three years of watching peptide and HRT care fragment across research-peptide forums, men's health "clinics", and concierge MDs that don't run modern panels. We agreed to build the version we'd actually become members of.
The model.
Wyoming C-corp, friendly-PC structure. Two-pharmacy architecture (Strive + Empower) selected over single-source. Tier economics modelled across 9 sheets; founder salaries set to zero through year one.
78 Crosby.
Lease signed on a ground-floor cast-iron space between Spring and Prince. Three thousand square feet. Build-out led by interior architect; equipment ordered against the gold-standard list.
The medical group.
Medical director hired. Friendly-PC formed in New York; New Jersey to follow. Two physicians, one PA, one phlebotomist, one concierge clinical operations lead.
Founding 500 opens.
Membership applications open. First panels drawn at 78 Crosby. The Ritual begins.
Wave 1B live.
BPC-157, TB-500, Thymosin Alpha-1, MOTS-c, Ipa/CJC compoundable again per HHS Feb 2026 announcement. Empower brings them onto the YOD formulary.
Eight rules
we work by.
One clinician.
The person who wrote your protocol reads your re-draw. No hand-offs.
One chart.
Your record lives in one place. Every clinician on it has read it before you arrive.
One protocol.
In writing. Revised every quarter. You read it before we begin.
Bloodwork first.
The marker decides what's prescribed. Never the request, never the trend.
Honest pricing.
Member price next to commercial price. Never wholesale. Never markup math.
Equipment is best-of-best.
Hologic, Living Earth Crafts, BIOMAX, SkinPen, Eclipse. No second-tier.
Single-venue feel.
If a service runs at a partner, the member never coordinates it. We do.
Quiet, not loud.
No exclamation points. No bro energy. No "stack". One sentence at a time.
If this is the kind of clinic you've been waiting for,
we'd be glad to read your application. Four minutes, no payment. A clinician writes back within two business days.
