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.

The Ark Protocol Stack

MUSCLE HEALED MONTHS AGO. THE TENDON DIDN'T You rested it. You did the physio. You paid for the adjustments. It got you most of the way back, then it stalled — and you've been training around it ever since. it was never a willpower problem. It's a supply problem Muscle is packed with blood vessels, so everything it needs to recover arrives fast. Tendon has a fraction of that supply. That's why the muscle bounced back and the tendon got left behind. The ARK Protocol Stack is built for the tissue that got left behind. BPC-157 Arginate and TB-500 in two daily capsules — studied for supporting blood supply and moving repair activity to where it's needed.

For the shoulder, elbow, knee or Achilles that stopped getting better.

$109.00

Stop training around it. Support the tendon and connective tissue that rest alone never reached.

No needles. No vials. No mixing. Two capsules of each, once a day, with water.

90 days to feel the difference. Tendon is slow tissue, so you get a full 90 days to judge it — or your money back.

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.

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.

Robert B.

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.

Why Your Tendon Stalled — And What Changes It"

You Did Everything Right. It Still Didn't Finish Healing.

You took the time off. You iced it, stretched it, strengthened it. You sat through the physio sessions and paid for the adjustments.
And it helped. Just not all the way.
Now it's the shoulder that pinches on the overhead press. The elbow that aches after a heavy pull day. The Achilles you warm up for ten minutes before you trust it.
You've dropped weight off the bar. You've swapped out lifts you used to love. You've started to wonder if this is just what training looks like now.
It isn't. But more rest won't change it — because rest was never the missing piece.

Muscle Is Fed. Tendon Isn't.

Recovery runs on delivery. Oxygen, nutrients and repair cells all travel by blood. Muscle is full of it. Tendon runs on a trickle, which is why it's the last thing to recover and the first thing to flare back up.

The Supply Line

BPC-157 is studied for its role in supporting the body's natural formation of new blood vessels at sites of tissue stress. More supply routes into low-flow tissue means more of what recovery needs actually gets there.

Opens up the supply your tendon has been missing.

The Delivery Crew

TB-500 is studied for its role in cell migration, which is how the body's own repair cells move toward the areas that need them. Supply gets resources there. TB-500 is about getting the workers there too.

One opens the road. The other moves the traffic. That's why they're taken together.

Healed Isn't The Same As Rebuilt.

When a tendon repairs, your body lays down new collagen fast, but not always neatly. Healthy tendon fibres run in tight, parallel lines, like the right side of this image. Rushed repair can leave them tangled, like the left.
That's the tissue that feels stiff, tweaks on a warm-up set, and never quite trusts a heavy load.
BPC-157 and TB-500 have been studied in research models for their role in more organised collagen structure during the body's natural repair process.

The goal isn't just healed. It's a tendon you can load again.

Tendon Is Slow Tissue. Here's How To Give It A Fair Shot.

Weeks 1–2: Build the habit. Two capsules of each, same time every day. Don't judge it yet.
Weeks 3–6: Watch the lifts. Note the one movement that bothers you most. Tendon progress shows up in training before anywhere else.
Weeks 8–12: Judge it here. This is the window the protocol is built around, and why your guarantee runs 90 days, not 30.

Keep doing your rehab. The protocol supports the work, it doesn't replace it.

THE RESEARCH BEHIND THE COMPOUNDS

What is in the bottles

Studied For Connective Tissue, Gut Health, And Neural Support

BPC-157 has been independently studied across more than thirty years of published research for its interaction with the body's natural vascularisation process, gut lining integrity, and gut-brain axis signalling. Three biological systems. One precisely dosed oral capsule.

800mcg Per Serving — The Research Standard Dose

Every serving of ARK BPC-157 contains 800mcg of BPC-157 Arginate — the dose referenced in the most rigorous available oral research. Not the minimum viable dose. The research standard dose. Two vegetable HPMC capsules. Thirty servings per jar.

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.

BPC-157 Arginate Not Standard Acetate

Most BPC-157 supplements use the standard acetate form. ARK uses BPC-157 Arginate — the stable salt form specifically chosen for oral delivery. More chemically stable. More consistent dose to dose. A formulation decision with a documented reason behind it.

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.

99.4% Purity — Batch Verified

Every batch of every ARK product is independently verified by HPLC analysis before a single unit goes on sale. Our minimum accepted purity threshold is 95%. Our batch average is 99.4%. The Certificate of Analysis for your specific batch is published on this page — not available on request, published before sale.

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 cardiovascular formula for the heart. A flexibility supplement for the tissue. And a joint product on top of the collagen, because the first one didn't work.

Eight bottles. Eight labels. Two compounds doing all the work.

ARK is those two — 800mcg BPC-157 Arginate, dual-fragment TB-500 — dosed at the research standard, in two bottles.

Eight biological systems. Two precisely dosed compounds.
800mcg BPC-157 Arginate and dual-fragment TB-500 — the doses used in the published research.

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.
