BPC-157 + TB-500 — the Wolverine protocol, dosing and what to expect

What Wolverine is and what it is studied for

BPC-157 is a pentadecapeptide studied for soft-tissue repair — tendon, ligament, muscle — and for the gut lining it was first isolated from. TB-500 is the active fragment of thymosin beta-4, studied for cell migration, angiogenesis and the organisation of new collagen at an injury site. Together they are the two most-studied peptides in the repair category, and the research interest in pairing them is that they act on different parts of the same healing cascade.

The Wolverine pen delivers both in one click, at doses built for daily use: 33.3 mcg of BPC-157 and 33.3 mcg of TB-500 per click. The TB-500 is a daily micro-dose, never a large periodic one. The point is patience — the pen supports the tissue while you rebuild load on it properly; it does not replace rehab, and it will not make an unready joint safe to load hard before its time.

Who it suits — and who should not run it

Written for the adult researcher recovering from a strain, a tendinopathy, a post-op stretch, or a joint that will not settle — who already has a diagnosis and a rehab or physio plan running alongside. The compound is an adjunct to progressive loading. Without a plan to load the tissue, there is little for it to support. The house exclusions:

Not for

• Active cancer or a recent cancer history — growth-factor signalling is the concern, and it is a hard exclusion.
• Pregnant, breastfeeding, or planning pregnancy in the next 6 months.
• Under 18.
• No rehab or physio plan in place.
• An acute injury that has not yet been assessed — imaging and a surgical opinion where relevant come first.

Start gate: your physician or physio has confirmed the injury is one this protocol suits, and the rehab plan is already running.

The house protocol

Once daily, subcutaneous, ideally near the injury site where that is practical, or the abdomen a hand's width from the navel when it is not — rotating between the two, or between nearby sites, to avoid repeat irritation. Same time each day works best. One pen = 300 clicks, each click 33.3 mcg of BPC-157 plus 33.3 mcg of TB-500.

Two phases: a four-week loading phase seven days a week, then a four-week maintenance phase five days a week with weekends off.

Clicks used: 28 days × 12 = 336, plus 20 days × 9 = 180, for 516 clicks → 2 pens (600 clicks available), leaving about 84 clicks — roughly 2.8 mg of each compound — unused at the end of the cycle. The optional 15-click day sits well inside the general research window for BPC-157 (100–1,000 mcg a day, with a practical soft ceiling around 500 mcg).

Keep the pen in the fridge between uses. Mild redness or warmth at the site is common and usually settles within a day; anything spreading or worsening rather than fading is not normal.

Week by week — what people typically notice and when

Isometrics early (weeks 1–2 are usually the safest way to keep loading tissue without provoking it), no full-intensity return before week 5 even if pain has eased, and 7–9 hours of sleep — tissue repair is disproportionately a night-time process. Everything outside the injured area trains as normal.

Labs we ask for before and during

Baseline labs are enough for this pen on its own; the week-8 repeat is optional unless you are stacking or something at baseline needs watching. Nutrition for repair: protein 1.6–2.0 g per kg, collagen with vitamin C 30–60 minutes before rehab sessions, omega-3 most days; vitamin D and magnesium round out the general supplements.

Stacking: what it pairs with

The obvious relative is the GLOW pen, which carries the same BPC-157 and TB-500 per click plus GHK-Cu for skin, hair and collagen. The two are not run together — GLOW already contains everything Wolverine does, and doubling the repair peptides adds nothing useful. Pick Wolverine when the goal is an injury; pick GLOW when the goal is aesthetic and recovery.

Wolverine sits comfortably alongside the GH-axis pairings used for recovery, such as CJC-1295 + Ipamorelin at night, and alongside a fat-loss cycle on retatrutide or tirzepatide when an old injury is what is stopping someone from training through it. Any stack moves the week-8 lab repeat from optional to required.

Common mistakes

• Loading the joint because it feels better. The pen eases pain before the tissue has remodelled. Follow the rehab plan's pace, not the sensation.
• Running it without a rehab plan. The compound supports progressive loading; it does not substitute for it.
• Treating it as a loading blast. Wolverine is a steady daily micro-dose over eight weeks, not a large periodic TB-500 shot.
• Injecting the same spot every day. Rotate between the injury site and the abdomen, or between nearby sites — repeat irritation is avoidable.
• Skipping the diagnosis. Imaging or a surgical opinion first for any acute injury; the pen does not tell you what is torn.
• Stopping rehab when the pen runs out. Tendon and ligament keep remodelling long after week 8.
