Why two bottles instead of one?

BPC-157 Arginate and TB-500 dual fragment do different jobs. Combining them into one capsule would mean cutting the dose of both. You get full doses of each, taken together.

Why four capsules a day?

Because that's the dose the research uses. Compressing it into one capsule would mean underdosing you and hoping you didn't notice.

How long before I notice anything?

Most people give it 30 to 60 days before they can tell. Tendon and connective tissue don't turn around in a week — that's the whole reason this takes patience. You've got 60 days to decide, which is why the guarantee runs that long.

Do I take it forever, or is there a protocol?

Run it for 60 to 90 days, then reassess. It's a protocol, not a daily multivitamin.

Capsules instead of injections — does that work?

That's the whole point of the arginate salt form. No needles, no reconstitution, no fridge, nothing to mix.

I've been using the Wolverine stack for about two months now, and I have to say, I'm really noticing a difference, especially with my shoulder injury. Initially, I was hesitant about trying it, but I'm glad I did because my shoulder feels more mobile and less painful. It’s great to finally get some relief after dealing with discomfort for so long.I've also noticed I'm able to get back to some activities I had put on hold. While I'm not completely pain-free yet, the improvement has been significant enough that I feel more confident moving forward. Overall, I would recommend giving it a try if you're dealing with something similar.

I've been using the BPC-157 recovery supplement for a few weeks now, and I've noticed a significant difference in my healing times after workouts. It's easier to bounce back from nagging injuries, and I feel more comfortable pushing my limits. Overall, it seems to be a solid addition to my recovery routine.

Steve T.

I recently started using these capsules after reading some positive information about them, and I really appreciate that I don’t have to deal with injections. It's so much more convenient for me, and it fits easily into my daily routine. I’m currently partway through the protocol and already feeling some improvements in my overall wellbeing.The process has been straightforward, and I find the capsules easy to swallow. I’m hopeful that as I continue, I’ll notice even more benefits. Overall, I’m pleased with my experience so far and would recommend giving them a try if you're looking for a non-injection option.

What is in the Capsules

TB-500 Dual Fragment — Ac-SDKP And Ac-LKKTETQ

Most TB-500 supplements use a single compound approach. ARK uses a dual fragment formula — Ac-SDKP 250mcg studied for its support of healthy tissue architecture maintenance, and Ac-LKKTETQ 500mcg studied for its support of the body's natural cellular coordination response. Two fragments. Two complementary biological pathways. More comprehensive than single compound alternatives.

Enteric-Coated — Both Fragments Reaching Absorption Intact

Standard capsules dissolve in stomach acid before reaching the small intestine where absorption occurs. ARK's TB-500 capsules are enteric-coated — specifically designed to pass through stomach acid intact and dissolve in the small intestine. Both Ac-SDKP and Ac-LKKTETQ arriving at the full stated dose. Every time.

What Happens Inside Your Body When You Run The ARK Protocol

The tissue stiffness building gradually over years of training. Not inevitable.

Every area of tissue stress triggers
a collagen response. In young tissue
that scaffolding is remodelled into
organised functional tissue. With age
that remodelling becomes progressively
less complete.

The result is tissue that moves with
less freedom. Joints that feel less
supple. A physical resilience that
requires more maintenance to sustain
than it used to.

Ac-SDKP — the tissue architecture
fragment in TB-500's dual formula —
is studied for its interaction with
myosin light chain kinase, supporting
the body's natural processes associated
with healthy tissue architecture
maintenance over time.

Your body already has the cells that biological maintenance depends on. TB-500 supports getting them where they are needed.

Your body produces the cells that
biological maintenance depends on
continuously — stem cells, progenitor
cells, immune mediators. The question
is whether they reach the areas that
need them in sufficient numbers and
at sufficient speed.

TB-500 is studied for its interaction
with G-actin sequestration — the
mechanism that enables cells to
reorganise their internal structure
and move directionally toward areas
of biological activity throughout
the entire body simultaneously.

More cells. Getting where they are
needed. Faster. More consistently.

Two Nature publications. The cardiovascular research signal that makes TB-500 unique in this category.

Two independent studies published in
Nature — in 2004 and 2007 — documented
Thymosin Beta-4's interaction with
cardiovascular tissue.

The findings include its interaction
with cardiac progenitor cells,
cardiovascular tissue remodelling,
and the body's natural vascular
support processes in cardiac tissue.

TB-500 is the only research compound
in this category with cardiovascular
tissue support findings published in
the highest-impact scientific journal
in the world. Twice.

For a heart that stays efficient
across decades. Not just a body
that performs now.

Four capsules,

one morning, done

How the habit actually fits into a morning.

TB-500 with breakfast

No fasting required. Take 2 capsules
at a consistent time each day —
with or without food. TB-500's
enteric-coated capsules pass through
stomach acid intact regardless of
whether you have eaten. The coating
does the protective work the fasting
does for BPC-157.

Why enteric-coated matters

Most TB-500 capsules dissolve in
your stomach — at pH 1.5 to 3.5 —
before reaching the small intestine
where absorption actually occurs.

ARK's TB-500 capsules are
enteric-coated. The coating resists
stomach acid completely — only
dissolving when it reaches the
small intestine where the pH rises
above 5.5.

Both active fragments — Ac-SDKP
and Ac-LKKTETQ — arriving where
absorption occurs. At the full
stated dose. Every time.

This is why TB-500 has no food
dependency. The coating does the
protective work regardless of
whether you have eaten.

People who stuck with it

Busy mornings, cluttered shelves, and one jar that replaced them.

Three bottles on the shelf, one of them always empty. This is one jar and it just works.

Daniel K. | Four months in

I tried the protocol or wolverine stack , high quality products

Sarah W. | Always travelling

Received the product quickly after order looking good

Olivia B. | Three months in

Four on the windowsill next to the kettle. Same time, same spot, every single morning.

Ruben H. | Morning ritual

It replaced three bottles I was buying. Cheaper, and I stopped forgetting two of them.

Why You Were Buying Eight Supplements?

A collagen for the joints. A gut formula for the lining. A nootropic for the focus. An anti-inflammatory for recovery. A vascular formula for circulation. A flexibility supplement for the tissue. A cardiovascular formula for the heart. A joint product for the wear.

Some companies call it the Wolverine Stack.
We call it The Protocol.
Two compounds. Replaces a lot of bottles.

Eight biological systems. Two precisely dosed compounds.
BPC-157 fasted every morning. TB-500 any time — with or without food.
No proprietary blends. Every ingredient disclosed. Every batch independently verified.

I had three half-finished bottles and no real routine, and I had quietly stopped noticing. One jar and four capsules solved a problem I was not admitting to.

"Great product! I've noticed a significant difference in my concentration and energy since I started taking it daily."

Daniel, 34

Working for me two months in I take on an empty stomach, also good for the mind gut brain connection

James

I'm happy to say I'm finally back in the gym after my recovery, and it's been going much better than I expected. I'm feeling more energetic and motivated to get back into my routine. Overall, it's great to be moving again!

Svea, 35

I switched to these two products, I was sick of buying so many supplements

60 days to feel the difference

Two bottles. Four capsules every morning. Sixty days is long enough to know whether that shoulder is actually moving — not long enough to talk yourself out of it. If nothing's changed, one email gets you every cent back. Opened bottles included.

Answers to your important questions

TB-500 is different. ARK's TB-500 capsules are enteric-coated — a physical barrier specifically designed to resist stomach acid and digestive enzymes and only dissolve in the small intestine where absorption occurs. The coating provides the same protection that fasting provides for BPC-157 — but mechanically rather than by timing. This is why TB-500 has no food dependency. The enteric coating does the protective work regardless of whether you have eaten or not.

BPC-157 is a peptide fragment — a chain of amino acids. When you eat food your stomach produces acid and digestive enzymes specifically designed to break down proteins and amino acids. BPC-157 is exactly the type of molecule those enzymes target. Taking it with food increases the risk that digestive enzymes begin breaking it down before it can be absorbed.
