Jay Campbell's Longevity Protocol

Slow the clock. Strengthen the system. Compounds built for the long game.

Goal: Cellular Longevity & Immune Resilience

A man and a woman stand side-by-side with their arms crossed on a gravel path in a sunlit park. They are dressed in casual athletic wear, with large green trees and a small stone bridge visible in the background.
This is not a crash course in anti-aging.
It’s a systematic, compound-driven approach to the biology of longevity — targeting telomere maintenance, thymic regeneration, immune resilience, tissue repair, and the hormonal signaling that holds it all together as you age.

This protocol is NOT for you if:

The Compounds

Epitalon

What It Does: A tetrapeptide that activates telomerase — the enzyme responsible for maintaining and extending telomere length. Originally developed by the Khavinson Institute in St. Petersburg, it remains one of the most researched longevity peptides in existence. It regulates pineal gland function, supports melatonin production, and has demonstrated lifespan-extending effects in long-term animal studies. If you’re serious about anti-aging peptides for longevity, Epitalon is non-negotiable.

Protocol Details:

Dose

2mg

Timing

PM

Frequency

Every day

Duration

20 days in a row, 3x per year

Administration

SubQ injection
Jay’s Note: Twenty consecutive days, three times a year. Don’t compress it and don’t skip days mid-cycle. The protocol structure is how you get the full telomerase activation effect.

Thymulin

What It Does: A thymic peptide that declines sharply and predictably with age — by your 60s, thymic output is a fraction of what it was at 20. Thymulin directly addresses immunosenescence by restoring T-cell production and thymic function. It’s a short, targeted intervention that resets immune competence at the source rather than chasing downstream immune markers.

Protocol Details:

Dose

1–5mg

Timing

AM or PM

Frequency

3–10 days on

Duration

3–10 days on, repeat every 60–90 days

Administration

SubQ injection
Jay’s Note: Thymulin is a short burst, not a sustained protocol — and that’s exactly how it should be used. Three to ten days, then give the immune system time to consolidate before the next run.

Vilon

What It Does: A dipeptide bioregulator originally developed by the same Russian research team behind Epitalon. It targets the thymus gland and works at the gene regulation level to restore immune competence and reduce chronic low-grade inflammation — one of the central hallmarks of biological aging. Where Thymulin resets, Vilon sustains.

Protocol Details:

Dose

0.5–2mg daily

Timing

SubQ or IM

Frequency

Daily

Duration

8–12 weeks on, 6 weeks off

Administration

SubQ or IM injection
Jay’s Note: Vilon and Thymulin address thymic health from two different angles. Running them in sequence — not simultaneously — is the smarter approach.

Klotho

What It Does: Klotho is an anti-aging protein that declines progressively after age 40, and its loss is directly associated with accelerated aging across multiple organ systems. Alpha-Klotho LR modulates IGF-1 and Wnt signaling, supports kidney function, reduces oxidative stress, and has well-documented neuroprotective effects. Populations with naturally elevated Klotho levels consistently live longer. This is one of the most compelling longevity targets in current research.

Protocol Details:

Dose

10mcg every 2 weeks

Timing

AM

Frequency

Once every 2 weeks ONLY

Duration

Adults 40+ can stay on permanently

Administration

SubQ or IM injection
Jay’s Note: Once every two weeks — no exceptions. Klotho is one of the few compounds in this stack where the dosing frequency is absolute. More is not better here.

FLGR-242

What It Does: A myostatin-inhibiting peptide that removes the biological brake on muscle development. In a longevity context, muscle mass is not an aesthetic goal — it’s a survival variable. Sarcopenia is one of the strongest independent predictors of all-cause mortality in aging adults. FLGR-242 supports lean mass preservation and recovery at the cellular level, which means you’re not just building muscle — you’re buying years.

Protocol Details:

Dose

2.5mg – 5mg

Timing

AM — SubQ injections ONLY

Frequency

Once every two weeks

Duration

12–16 week cycles, 8 weeks off

Administration

SubQ injection only
Jay’s Note: Start at 2.5mg for your first cycle and assess tolerance before moving up. SubQ only — this is not negotiable with FLGR-242.

GHK-Cu

What It Does: A naturally occurring copper peptide that activates over 4,000 genes associated with tissue repair, collagen synthesis, anti-inflammatory response, and antioxidant protection. GHK-Cu is one of the most versatile compounds in this entire stack. Its systemic regenerative effects make it a daily anchor for any serious longevity protocol — not a nice-to-have.

Protocol Details:

Dose

1.7mg

Timing

AM

Frequency

Every day

Duration

8 weeks on, 8 weeks off

Administration

SubQ injection
Jay’s Note: GHK-Cu is the quiet workhorse of this stack. You’re running it every day because its regenerative benefits are cumulative — and the eight-week break keeps the receptors responsive.

BioThymus

What It Does: BioThymus is the Vladonix A-6 thymus peptide bioregulator in capsule form — a natural peptide complex isolated from the thymus glands of young animals. The thymus is the organ that trains and deploys your T-cells, and its output drops hard with age. Research shows chronic stress and environmental load can reduce thymic function by up to 40% in adults. BioThymus works at the cellular level to restore protein synthesis inside immune cells, support T-lymphocyte maturation, and help rebuild immune competence after illness, stress, or prolonged physical demand. In the context of this stack, it’s the oral complement to Thymulin and Vilon — covering the same biological target through a different delivery mechanism and a longer sustained run.

Protocol Details:

Dose

1–2 capsules

Timing

With meals (AM and/or PM)

Frequency

1–2 times daily

Duration

30 days on, 2 months off — 2–3x per year

Administration

Capsule
Jay’s Note: BioThymus gives you the thymus bioregulator in a format that requires no reconstitution — which makes it the practical daily anchor for thymic support while Thymulin and Vilon handle the more targeted intervention phases.

Frequently Asked Questions

Do I need to run all seven compounds simultaneously?
No — and for most people, that’s not the right approach anyway.
Epitalon, Thymulin, and Vilon all target thymic and immune function through different mechanisms.
Running Thymulin first as a short burst (3–10 days), followed by Vilon as the sustained phase, is a smarter sequencing than stacking all three at once.
Klotho and GHK-Cu run on their own independent schedules and can be layered in at any point.
Start with what your bloodwork tells you needs the most attention, and build from there.
The focus here is on the biology of aging — telomere length, thymic function, immune resilience, and systemic regeneration.
Muscle preservation through FLGR-242 appears in both protocols, but the context is different.
In the Longevity Protocol, lean mass retention is a longevity marker, not a performance goal.
Every other compound in this stack is chosen because it addresses a specific mechanism of biological aging — not body composition or acute performance.
Yes — and for most men over 40, TRT is the hormonal foundation this stack belongs on top of.
None of the compounds in this protocol interfere with exogenous testosterone.
Get bloodwork at the six-week mark to confirm IGF-1, inflammatory markers, and your standard hormone panel are tracking where you want them.
