Four pillars. One physician-directed plan.
Peptides, CO2 laser, therapeutic plasma exchange and concierge membership: four ways into the same measured-not-guessed medicine, built and delivered by Dr. Dusan Sajic, MD, PhD, a board-certified dermatologist and longevity physician. Start with the one that fits where you are.
01 · InternalPeptidesEvidence-ranked, pharmacy-grade, tracked in your bloodwork. From $99/mo by telehealth.
02 · SkinCO2 LaserPhysician-delivered fractional resurfacing that resets sun-damaged skin as a field.
03 · Apex exclusiveTherapeutic Plasma ExchangeA 90-minute clinical reset for the inflammatory load of aging.
04 · EverythingMembershipsDiagnostics, hormones, peptides and skin under one plan. Laser included complimentary.
How it works.
Three steps from where you are now to looking and feeling your best. Whichever pillar you start with, the loop is the same: measure, treat, re-measure.
Book a consultation
A private discovery call to understand your goals and map your starting point. Virtual from anywhere, or in person in Guelph or Beverly Hills, available within 48 hours.
Get your personalized plan
Diagnostics set your baseline: TruAge biological age, bloodwork read against optimal ranges, skin analytics. Then one physician-directed protocol, inside and out.
Look and feel your best
Follow your plan with concierge support as results show in skin, energy and bloodwork, re-measured at 30, 60 and 90 days. If a number isn't moving, the plan changes.
Peptides, prescribed properly.
Peptides are accelerators, not foundations. Used on an unmeasured body they amplify dysfunction; used on a validated one they are among the most powerful tools in preventative medicine. So we rank every peptide by the strength of its human evidence, prescribe pharmacy-grade product only, and track what it is doing in your bloodwork.
- Tier 1, GLP-1s: semaglutide and tirzepatide, the strongest human evidence in the class, including randomized data on the pace of biological aging
- Tiers 2–4: tesamorelin, BPC-157, TB-500, MOTS-c, NAD+ and blends, with defined monitoring and short supervised courses where evidence is early
- Tier 5: the compounds we will not sell you until credible human evidence exists
Two ways in: physician-reviewed telehealth from $99/month, or a consultation that builds your protocol on your labs. Not sure yet? Download Peptides 101, free.

Peptides 101: A Physician's Honest Guide.
A clinician-written, jargon-free briefing on what each peptide actually does, what the human evidence really says, and the exact biomarkers to track before you spend a dollar. No hype, no grey-market sales pitch: just the honest version, from a physician who publishes on this.
- The five evidence tiers, and which peptides we won't sell you
- What to measure first, so a peptide accelerates health instead of dysfunction
- How GLP-1s, BPC-157, MOTS-c and NAD+ fit into a tracked plan

Every CO2 pass delivered personally by Dr. Sajic
CO2 is not one treatment. It is a dial.
Shallow settings give you a glow. Depth, in the right hands, gives you a reset: sun-damaged keratinocytes shed, DNA repair switched on, collagen rebuilt as a field rather than a spot. Dr. Sajic's published work showed 83.3% of patients achieving at least a 25% reduction in pre-cancerous actinic keratoses, with skin-quality scores improving alongside.
- Physician-operated, at the depth your skin can actually use, not the depth a technician is allowed to set
- Prepared going in (internal readiness, barrier, DNA-repair skincare) and protected coming out
- Twelve or more skin-quality parameters scored at baseline and re-measured at 30, 60 and 90 days

Remove the old. Don't add the new.
Most longevity interventions add something. Therapeutic plasma exchange (TPE) subtracts: a 90-minute clinical procedure that removes your plasma, with its accumulated inflammatory proteins, autoantibodies and molecular debris, and replaces it with 5% albumin. Fifty years of clinical history, honest modern evidence in both directions, and outcomes we measure rather than promise.
- 90 minutes per session, zero downtime, dedicated nurse and physician oversight
- 3–5 sessions per course over 2–4 weeks, with pre and post biomarker panels included
- $10,000 per session standard; $7,000 at the Apex member rate, with four sessions a year included in Apex Superhuman
- <1% serious complication rate with experienced teams
One physician. One plan. Every system.
Executive health that includes your largest organ. Most programs measure your insides with scans and bloodwork, then stop. Membership puts your diagnostics, hormones, metabolism, peptides and skin under a single physician-directed protocol, and includes laser and signature skin treatments complimentary, because the outside should reflect the work being done on the inside.
Map your inner health
TruAge epigenetic age, full bloodwork read against optimal ranges, multi-cancer screening and imaging reveal how you're truly aging.
See every test →Read your largest organ
Non-invasive skin diagnostics read the inflammation, hormones and metabolism beneath the surface. Then laser and skin treatments, included.

One physician-led protocol improves internal and external health at the same time, re-measured at 30, 60 and 90 days, so results show and last.

The most expensive decision is the one you keep postponing.
Aging doesn't announce itself. It compounds quietly: a little less energy, slower recovery, a few markers drifting the wrong way, until one day it feels like it happened all at once. The people who act early are the ones who get the most life back.
- Telehealth, $99–$299/mo: peptides, GLP-1 and hormones by virtual intake
- Consultation, $150 or $499: your baseline plus a physician plan. Deposit applied to testing
- Membership, from $4,999/yr: everything under one physician-directed program
Straight answers.
Where is Sajic Longevity located?
Two clinics: deRMA Skin Institute in Guelph, Ontario (33 Farley Drive, Unit 8), serving Toronto and the Greater Toronto Area, and a Beverly Hills, California location at 444 N Camden Dr serving Los Angeles. Virtual consultations and telehealth programs are available across Canada and most US states.
Which service should I start with?
If you want a specific medication (GLP-1, TRT, a peptide), telehealth from $99/month is the fastest route. If you want to know how you're actually aging first, book a consultation: the $150 nurse or $499 physician deposit is applied in full to diagnostic testing. If you want everything under one plan with skin treatments included, membership starts from $4,999 per year and is accepted by application.
Is the CO2 laser performed by Dr. Sajic himself?
Yes. Every CO2 pass is delivered personally by Dr. Sajic at the depth your skin can use, with baseline skin-quality scoring and re-measurement at 30, 60 and 90 days. Members receive laser and signature skin treatments complimentary.
Who is therapeutic plasma exchange for?
TPE is our most powerful intervention against the inflammatory load of aging and is offered as an Apex-exclusive service ($10,000 per session standard, $7,000 at the member rate, four sessions a year included in Apex Superhuman). Candidacy is decided after diagnostics and a physician consultation.
Do you prescribe peptides without testing?
Telehealth programs include a physician-reviewed intake and medical clearance before anything is prescribed. For the full peptide framework we measure hormones, inflammation, metabolism and biological age first, then add peptides with precision and re-test to prove they're working.
