BPC-157 Arginate + TB-500 Dual Fragment

Some companies call it the " WOLVERINE STACK "We call it The Protocol.

Support faster recovery between training sessions — BPC-157 and TB-500 working simultaneously

Maintain the tissue quality and flexibility that an active life demands

Support gut lining integrity and the gut-brain connection that energy and focus depend on

Run the protocol the longevity research community most consistently references

BPC-157 supports the local biological environment — vascularisation, connective tissue activity, gut lining integrity. TB-500 coordinates the body's systemic cellular response — directing cellular activity throughout the entire body. Together they support what neither addresses alone. This is the protocol built for the human who demands more from their biology — and from their supplier.

The ARK Protocol Stack
BPC-157 Arginate 800mcg + TB-500 Dual Fragment 750mcg

The combined protocol that addresses tissue recovery and biological maintenance from two mechanistically distinct and complementary directions simultaneously.

BPC-157 Arginate — 800mcg per serving
Delivered as the arginate salt form — more chemically stable for oral delivery than standard acetate and better suited to consistent daily protocols. Studied across more than three decades of published research for its interaction with VEGF-driven vascularisation, growth hormone receptor activity in connective tissue, gut lining integrity support, and gut-brain axis signalling through the enteric nervous system.

TB-500 Dual Fragment — 750mcg per serving
Ac-SDKP 250mcg — the anti-inflammatory and tissue architecture fragment. Studied for its interaction with myosin light chain kinase supporting healthy tissue architecture maintenance and the body's natural anti-inflammatory processes.

Ac-LKKTETQ 500mcg — the cellular coordination fragment. Studied for its interaction with G-actin sequestration supporting the body's natural cellular mobility and directional movement of cells toward areas of biological activity throughout the entire body.

Delivered in an enteric-coated HPMC capsule — passing through stomach acid intact and dissolving in the small intestine where absorption conditions are more favourable for both active fragments.

Why the combination
BPC-157 supports the local biological environment at areas of tissue stress. TB-500 supports the body's systemic cellular coordination response throughout the entire body. Each addresses the biological ground the other does not. Together they offer broader biological coverage than either compound provides individually — which is why the combined protocol is the most consistently referenced approach in the longevity research community.

Formulation transparency
Every ingredient disclosed. Every batch independently verified at 99.4% purity by HPLC analysis. Batch-specific Certificate of Analysis published on each individual product page before a single unit ships. No fillers. No proprietary blends. No undisclosed ingredients.

Two of the most researched bio-active compounds available

One precision longevity protocol.

Why Your Recovery Takes Longer Than It Used To — And What The Research Says About It"

Physical demands that used to feel routine may require more recovery time as biological processes change over time.

The Tissue Stiffness That Builds Gradually — Is Not Inevitable"

If your joints move with less freedom than they did five years ago — the research points to a specific biological process that changes with age. The ARK stack is studied to support the body's natural tissue architecture maintenance — so you stay mobile, flexible, and physically capable for longer.

Training harder is only half the equation. How well you recover between sessions determines how much of that work your body keeps. Supporting the body's natural recovery response is the variable most people underinvest in — and the one that compounds most significantly over time.

A heart that stays efficient across decades is not a matter of luck. TB-500 is the only research compound with cardiovascular tissue support findings published twice in Nature — the highest-impact journal in science."

Everything You Need. Nothing You Don't.


More organised tissue. Better recovery between sessions. Gut lining integrity that supports everything downstream from energy to mood. These are the outcomes the research community has consistently associated with BPC-157 and TB-500 across three decades of published science. ARK delivers both at research-standard doses — verified at 99.4% purity — in one complete protocol."


Better recovery. More resilient tissue. Sustained physical capability. These outcomes require two things happening simultaneously — the local biological environment being supported at areas of tissue stress, and the body's systemic cellular coordination response being active throughout. BPC-157 and TB-500 provide both."

Then the existing mechanism explanation follows unchanged.

Local Support. Systemic Coordination. Complete Coverage.

BPC-157 is studied for its support of local vascularisation and cellular activity at specific areas of tissue stress. Its interaction with the body's natural blood vessel formation process supports nutrient and oxygen delivery to areas where the body's natural maintenance activity is occurring. Alongside this, BPC-157 is studied for its interaction with connective tissue cellular activity, gut lining integrity, and the gut-brain axis signalling network that connects digestive health to broader systemic function.

TB-500's dual fragment formula approaches the same biological challenge from a fundamentally different direction. Ac-SDKP is studied for its support of the body's natural anti-inflammatory response and healthy tissue architecture maintenance — the biological processes that preserve tissue quality and structural integrity over time. Ac-LKKTETQ is studied for its interaction with the body's natural cellular coordination response — supporting the directional mobility of cells throughout the entire body toward areas of biological activity.

The two compounds operate through complementary biological pathways — each addressing the biological ground the other does not. BPC-157 supports the local biological environment. TB-500 supports the body's systemic cellular response. Together they offer broader biological coverage than either compound provides individually — which is why the combined protocol is the most consistently referenced approach in the longevity and research community.

THIS IS WHAT COMPLETE SUPPORT LOOKS LIKE

The gap in BPC-157's coverage is exactly where TB-500 works. And vice versa. Together they offer complete biological coverage that neither compound provides alone."
You train consistently and you take recovery seriously. But there are areas of recurring tissue stress that conventional approaches have not fully resolved — and a recovery ceiling that feels lower than your effort justifies.

You are not looking for a shortcut. You are looking for compounds with real research behind them, a supplier whose documentation you can verify, and a protocol that addresses the biology rather than managing around it.

BPC-157 supports local vascularisation and connective tissue cellular activity. TB-500 coordinates the body's systemic cellular response and supports healthy tissue architecture throughout the body.

Together they support the recovery, tissue quality, and physical resilience that sustained performance demands. This is the protocol built for the person who takes all of this as seriously as you do."

HOW THE TWO COMPOUNDS WORK TOGETHER

Two Complementary Research Compounds — This is what both compounds supporting the body's natural biological processes looks like simultaneously."


On the left BPC-157 supports local vascularisation at the area of tissue stress — studied for its support of the body's natural vascularisation process"
supporting cellular activity in connective tissue, and maintaining gut lining integrity and gut-brain axis signalling. On the right TB-500's dual fragments work systemically — Ac-SDKP supporting healthy tissue architecture throughout the body, Ac-LKKTETQ promoting cellular mobility toward the same area where BPC-157 is active. Two systems. One location receiving support from both directions at the same time.

For The Human Who Refuses To Accept Decline As The Default

You have tried the conventional approaches. They helped — temporarily. What you are looking for is something that addresses the biology rather than managing the symptoms.
