Physician-Reviewed · 503A & 503B Pharmacy Network · All 50 US States
Dr. Dusan Sajic, MD, PhD, FRCPC, FAAD
Medical Director, Sajic Longevity Clinic
Updated ·9 min read
The longevity and peptide space has been dominated by unregulated providers, inconsistent compounding quality, and zero accountability to a real physician. Sajic Longevity Clinic changes that. Every prescription is made by a licensed physician reviewing your specific goals, history, and biology. Not an algorithm.
"Anything that can give you benefit can also give you harm at the wrong dose, in the wrong biological context, without monitoring. That principle is why Sajic Longevity Clinic exists."

The Accountability Problem
The peptide and longevity market has exploded over the last five years — and so has the risk to patients navigating it alone. Unregulated compounders, overseas suppliers, no physician oversight, no individualised dosing, no monitoring, and no accountability when something goes wrong.
Anyone can sell peptides. Almost nobody prescribes them properly. This is what we are changing.
01
Physician-Reviewed — Every Single Intake
— Not an algorithm. A real doctor.
Every intake is reviewed by a team of licensed physicians personally vetted by Dr. Sajic — selected for their clinical rigour, their alignment with personalised medicine principles, and their commitment to patient safety. A real physician reviews your case and makes every prescribing decision.
What Helps:
Eating enough protein (crucial for skin and muscle)
Reducing excess sugar and refined carbs
Maintaining healthy muscle mass
Strategic supplementation: Creatine, Hydrogen support
02
503A & 503B Licensed Pharmacy Network
— Pharmaceutical-grade compounding, batch-tested
Every medication is fulfilled through licensed compounding pharmacies operating under 503A or 503B FDA registration — the regulatory framework that governs pharmaceutical-grade compounding in the United States.
This is the difference between regulated, quality-tested pharmaceutical compounding and unregulated supplement-level quality with no batch testing, no sterility assurance, and no regulatory accountability.
What Helps:
Eating enough protein (crucial for skin and muscle)
Reducing excess sugar and refined carbs
Maintaining healthy muscle mass
Strategic supplementation: Creatine, Hydrogen support
03
All 50 US States — Legally and Properly
— Not through loopholes or grey-area memberships
Telehealth prescribing is jurisdiction-specific and compliance-intensive. Sajic Longevity Clinic is structured to operate legally across all 50 US states — through proper medical licensing, telehealth registration, and pharmacy network compliance in each jurisdiction.
What Helps:
Eating enough protein (crucial for skin and muscle)

04
Personalised — Not Cookie-Cutter
— Built around your biology, history, and goals
The intake process captures your goals, medical history, current medications, and baseline health context. A vetted physician reviews this and either approves a personalised prescription, requests additional information, or recommends an alternative path — including genetic screening, home bloodwork, or in-person evaluation when indicated.

05
Ongoing Access — Patient Portal
— A monitored programme, not a subscription box
Your relationship with Dr. Sajic doesn't end at the prescription. Every patient has direct access through the patient portal for follow-up, side effect management, dose adjustment, and monitoring.

Peptides Available Through the Clinic
Peptide therapy is one of six service categories offered through Sajic Longevity Clinic — and the area that most patients ask about. Every peptide is prescribed individually based on goals and (where indicated) baseline labs. Research-phase compounds are offered with full education about evidence, risks, and alternatives.
GH
Performance & Growth Hormone Peptides
— GH secretagogues and metabolic peptides
Growth hormone secretagogues and metabolic peptides for body composition, recovery, sleep quality, and mitochondrial function. Each prescribed individually based on goals and baseline labs.
BPC-157, TB-500, and combination protocols for injury recovery, tendon and ligament healing, gut repair, and systemic anti-inflammatory support. Offered with full research context.
Available compounds:
BPC-157 — body protection compound, research-phase
↗ Research compounds are not FDA- or Health Canada-approved for human use. Eligibility is determined case-by-case by Dr. Sajic with full education about evidence, risks, and alternatives provided during intake review.
How It Works — The Intake Process
The intake process is designed to gather the information Dr. Sajic needs to make a genuinely individualised prescribing decision — and to protect you from receiving something inappropriate for your biology, your history, or your current medications.
01
Choose Your Service and Start the Intake
— Visit sajicskin.com/pages/telehealth
Select the service that matches your goals. Each service has its own confidential intake form — a medical questionnaire covering your health history, current medications, goals, and any relevant baseline testing you may already have.

✓ Coming to the Platform — Measurement-Led Personalisation
Being integrated now: home bloodwork panels, genetic cancer screening (CancerGuard and similar), and skin-based biomarker testing through Skin Life Analytics — so that your longevity protocol is built on your actual biology, not a questionnaire alone. Measure first, prescribe second, track always.
Peptides + Skin — The Cellular Connection
Sajic Longevity Clinic and Sajic Skin Science share the same clinical philosophy: treat aging at the cellular level, from every direction simultaneously. Internal medicine and external skin health are not separate disciplines. At Sajic, they are one integrated programme — with the same physician overseeing both, the same data informing both, and the same commitment to measurement and accountability across all of it.
The Mirror Principle
"Your skin is the most visible biomarker of your internal biology. When we optimise what's happening inside — hormonally, metabolically, cellularly — the skin reflects that improvement in ways that no aesthetic procedure alone can replicate."

Growth Hormone Peptides + Skin Regeneration
— Sleep, recovery, dermal repair
Growth hormone secretagogues improve sleep quality, recovery capacity, and growth hormone pulsatility — all of which drive skin cell regeneration and dermal repair. NAD+ and MOTS-c work on the same mitochondrial pathway that we track through Skin Life Analytics — measurable, comparable, accountable.

Tissue Repair Peptides + Recovery After Procedures
BPC-157 and TB-500 protocols are increasingly used to support recovery after aesthetic procedures — laser resurfacing, RF microneedling, and biostimulator injections — by accelerating tissue repair and reducing inflammatory downtime. Used alongside Rejuvenat® topically and Renutriate® for barrier support, they form an inside-out recovery protocol.

Hormone Optimisation + Skin Longevity
— BHRT, TRT, and how it amplifies topical results
Oestradiol directly upregulates collagen synthesis, increases skin thickness, and maintains hydration. Testosterone in physiological ranges drives fibroblast activity. Skin treated with Rejuvenat® in a hormonally optimised environment responds dramatically better — and the results of laser, RF, and biostimulatory treatments last significantly longer.
