Recovery

Rebuild

BPC-157TB-500

Rebuild is a dual-peptide recovery protocol that pairs BPC-157 and TB-500, the pairing informally known as the Wolverine Stack, to address tissue healing on two fronts in one cycle: the signal that starts the repair, and the rebuild that follows.

By pairing the two, Rebuild drives a faster and more complete repair response than either peptide produces alone — supporting recovery from acute injury, tendon and joint healing, and the range of motion that returns when tissue rebuilds cleanly.

Rebuild combines BPC-157 and TB-500 into one injection when the goal is targeted repair of a specific injury or tissue site — a torn tendon, a joint that hasn't fully come back after surgery, a chronic issue that hasn't resolved through standard rehab. Running the two together, the signal and rebuild phases work in the same window rather than being managed separately.

BPC-157 (Signal): Signals soft tissue healing to a specific site — driving the repair response at tendons, ligaments, gut lining, and joint tissue.
TB-500 (Rebuild): Supports the cellular work and tissue flexibility that carry the repair signal into actual reconstruction.

Rebuild is administered as a subcutaneous injection, with BPC-157 and TB-500 compounded together in the same vial. Your clinician sets the frequency based on your intake, the site of the injury, and how acute the presentation is.

Where your protocol ultimately settles depends on the goal. Acute injury presentations typically run shorter, more intensive cycles; longer-term or recurring issues may warrant a longer arc. That's a decision your clinician makes with you at intake and revisits at each check-in.

Everything you need to inject at home, in one shipment:

The vial, lyophilized and ready to reconstitute
Bacteriostatic water for reconstitution
Insulin syringes
Alcohol prep pads
Step-by-step reconstitution and injection instructions in your care portal

Every prescription is written by a US-licensed clinician after reviewing your intake. It's compounded at a licensed US 503A pharmacy held to cGMP manufacturing standards, and every batch is third-party tested for potency, sterility, pH balance, and endotoxins before it ships. Temperature-controlled from the pharmacy to your door. Full results in the Quality panel below.

How it works

The path to your protocol.

From your intake to your door, every protocol is built by a licensed US clinician around who you are and where you're headed.

Take the assessment.

[01]

Your goals, your body, your history - everything your clinician needs to build a protocol around you.

Clinician-built protocol.

[02]

A US-licensed clinician reviews your intake, selects the right compound, dose and cycle, and approves your protocol within 24 hours.

Delivered. Then evolved.

[03]

Compounded at a licensed US pharmacy and shipped discreetly. Monthly check-ins keep your clinician close and your protocol evolving with you.

Start your protocol

Tested every batch. Independently.

Every SYNC protocol is compounded at a licensed US 503A pharmacy and third-party tested — every batch, against four pharmacopoeia standards. If a batch doesn't pass all four, it doesn't ship.

Potency

Passed

Confirms the vial contains what the label says — active ingredient within ±10% of prescribed concentration.

Passed

Tested against USP 797 to confirm the compound is free from bacterial or fungal contamination.

pH balance

Passed

Balanced to minimize irritation at the injection site and remain compatible with the body.

Endotoxins

Passed

Tested against USP 85 to confirm bacterial endotoxin levels are within safe limits — protecting against fever and adverse reactions.

FROM THE COMMUNITY

The ones who stopped guessing

Excellent4

"I've never had healthcare feel this frictionless. From the intake to messaging my clinician, everything just works - I ask a question, I get a real answer, and my protocol keeps moving. It's the kind of experience I wish more of healthcare felt like."

Jackson P.4Metabolic protocol

"My cycle 2 protocol was genuinely different from cycle 1- the dose had been adjusted and one of the compounds swapped based on how I'd responded. It's the first time I've seen personalization actually happen, not just be marketed."

Chase H.Longevity protocol

"I'd done my research on peptides - the question wasn't whether to take them, it was who to trust. SYNC was the first place where the intake felt like actual medicine. My physician walked me through her reasoning before prescribing anything."

BPC-157 does the signalling work — it tells the body where and how to start soft tissue repair. What it doesn't do alone is drive the cellular work and tissue flexibility that carry the signal through the actual rebuild. That's what TB-500 adds. Together in one protocol, the two peptides reinforce the signal and rebuild phases of tissue repair at the same time — which is why this pairing is the most-used two-peptide protocol for targeted injury work.

Rebuild is two peptides focused on the signal and migration phases — the pairing for targeted, acute injury work. Repair adds KPV and GHK-Cu to cover systemic inflammation and the later-stage connective tissue rebuilding phase. If the presentation is a specific injury or acute recovery, Rebuild is often the right protocol. Repair is the protocol for systemic wear, multiple sites, or when the later-stage rebuilding phase needs support too.

Yes, and it commonly is. Rebuild runs cleanly alongside single molecules like Sermorelin or NAD+, and can pair with GH-axis protocols like Perform when the clinical picture calls for it. Share what you're on at intake — including hormone therapy or ongoing medication — and your clinician builds around it.

Tissue repair builds progressively. Most people notice recovery changes around weeks three to five — faster session recovery, less stiffness at the injury site, better range of motion. Structural changes to tendons and ligaments build through months two and three. Cycles typically run 60-90 days, though your clinician may set shorter arcs around specific injury or longer ones for chronic issues.

Rebuild works by supporting the body's own repair systems rather than replacing anything — no dependence, no withdrawal, no rebound. Tissue changes built during the cycle hold; the rebuilding doesn't unwind when the peptides clear. Some people run a single 60-90 day cycle around a specific injury, others cycle around training load. Your clinician sets the rhythm at check-in.

Any time, from your account. If your goals change, message us and we'll adjust your protocol with you. No calls, no retention scripts, no penalty for pausing between cycles.

Message us and we'll expedite a replacement — most reorders ship the same day. Your subscription is timed so this shouldn't happen, but if life gets in the way, we've got you.

No insurance — SYNC is cash-pay, which lets us build every protocol around your body rather than around what an insurer will approve. HSA and FSA cards work at checkout like any credit or debit card. Reimbursement depends on your individual plan — if you're unsure, check with your provider or ask your clinician for a Letter of Medical Necessity.
