What BPC-157 is and what it is studied for
BPC-157 is a pentadecapeptide — fifteen amino acids — originally isolated from a protective protein in human gastric juice. It is studied for soft-tissue repair (tendon, ligament, muscle), for the gut lining, and for the way new blood vessels organise around an injury. In research settings the reported effect is tissue that tolerates load sooner, not tissue that stops hurting while staying weak.
The single pen exists for the researcher who wants BPC-157 without TB-500. That is the right call when the target is the gut rather than a joint, or when a previous Wolverine cycle showed that one half of the pairing was doing the work. The house window is deliberately narrow — 150–500 mcg per injection, once or twice a day — and the protocol below sits inside it from the first click to the last.
Who it suits — and who should not run it
Written for the adult researcher with a diagnosed soft-tissue problem — a tendinopathy, a muscle strain, a post-surgical joint — or a gut lining that has been assessed and is being managed, who already has a rehab or nutrition plan running alongside. BPC-157 is an adjunct to that plan. The house exclusions:
Not for
- Active cancer or a recent cancer history — growth-factor and angiogenesis signalling is the concern, and it is a hard exclusion.
- Pregnant, breastfeeding, or planning pregnancy in the next 6 months.
- Under 18.
- An acute injury that has not yet been assessed — imaging and a surgical opinion where relevant come first.
- No rehab, physio or dietary plan in place for the thing you are trying to repair.
Start gate: your physician or physio has confirmed this protocol suits the problem, and the plan it supports is already running.
The house protocol
Subcutaneous, near the injury site where that is practical, or the abdomen a hand's width from the navel when it is not — rotating sites so nothing gets injected twice in a row. For a gut target the abdomen is the site every time. One pen = 300 clicks. The 10 mg pen delivers 33.3 mcg per click; the 5 mg pen delivers 16.7 mcg per click, so the same dose is twice the clicks.
Two phases: a four-week loading phase at two injections a day, then a four-week maintenance phase at one injection a day. The per-injection dose does not change — only the frequency does. The general research window is 100–1,000 mcg a day with a practical soft ceiling of 500 mcg per injection, and the house never schedules more than two injections a day.
| Pen | Dose per injection | Clicks | Frequency | Timing | Cycle |
|---|---|---|---|---|---|
| BPC-157 10 mg (33.3 mcg/click) | 300 mcg | 9 | Twice daily, 7 days a week | Morning and evening, near the injury site where practical | Weeks 1–4 — loading (600 mcg/day) |
| BPC-157 10 mg | 300 mcg | 9 | Once daily, 7 days a week | Evening | Weeks 5–8 — maintenance |
| BPC-157 5 mg (16.7 mcg/click) | 250 mcg | 15 | Twice daily, 7 days a week | Morning and evening | Weeks 1–4 — loading (500 mcg/day) |
| BPC-157 5 mg | 250 mcg | 15 | Once daily, 7 days a week | Evening | Weeks 5–8 — maintenance |
| Soft ceiling | 500 mcg per injection (15 clicks on the 10 mg pen) | 15 | Never more than twice a day | — | A heavy rehab day, not a step |
Click total on the 10 mg pen: 28 days × 18 = 504, plus 28 days × 9 = 252, for 756 clicks → 3 pens (900 clicks), leaving 144 clicks — about 4.8 mg — at the end of the cycle. The 5 mg pen runs the same schedule at 1,260 clicks — five pens — and suits a short, low-dose gut course rather than a full repair cycle.
Keep the pen in the fridge between uses. Mild redness at the site is common and settles within a day; anything spreading or worsening is a same-day message to your coach.
Week by week — what people typically notice and when
| When | What is typically reported |
|---|---|
| Weeks 1–2 | Subjective easing — less background discomfort at the site, movement feels less guarded. For a gut target, fewer bad days. The trap is loading harder because it feels better. |
| Weeks 3–4 | Load tolerance starts to improve in step with the rehab plan. The first hard session of the week stops being the one you dread. |
| Weeks 5–6 | Frequency drops to once daily. Range of motion and day-to-day use of the area are typically the clearest change in this window; nothing should get worse on the lower frequency. |
| Weeks 7–8 | Consolidation. Symptoms are generally well settled; the tissue is stronger but still mid-remodel, and the end of the pen is not the end of the plan. |
The compound supports progressive loading; it does not create it. Isometrics early, no full-intensity return before week 5 even when pain has eased, and 7–9 hours of sleep. For a gut target the equivalent discipline is the agreed diet plan — the pen is not a licence to test the foods that caused the problem.
Labs we ask for before and during
| Marker | When | Why it is on the list |
|---|---|---|
| Full blood count | Baseline | General health check before starting |
| CRP | Baseline · week 8 | Baseline inflammation marker; the repeat shows direction of travel |
| Cystatin C (never creatinine alone) | Baseline | Kidney measure not distorted by muscle or creatine |
| Liver panel (ALT, AST, GGT, bilirubin) | Baseline | General liver check before an 8-week cycle |
| Fasting glucose | Baseline | General metabolic baseline |
| Faecal calprotectin | Baseline · week 8 (gut target only) | The objective read on gut-lining inflammation when that is the goal |
Baseline labs are enough for the pen on its own; the week-8 CRP repeat tells you whether the easing you feel is matched by the number. Nutrition for repair: protein 1.6–2.0 g per kg, collagen with vitamin C before rehab sessions, omega-3 most days; vitamin D and magnesium as the general supplements.
Stacking: what it pairs with
The obvious partner is TB-500, and the obvious question is whether to run the two as separate pens or as the Wolverine combination. Separate pens suit the standalone TB-500 loading schedule — a larger dose twice a week — next to a daily BPC-157 micro-dose; the combo pen suits daily dosing of both. For skin and hair on top of repair, the GLOW pen already contains BPC-157 and is never run alongside this one.
For a gut target, KPV is the usual second compound — an anti-inflammatory tripeptide working on a different pathway — and the two together are the backbone of the KLOW pen. BPC-157 also sits comfortably alongside a nightly CJC-1295 + Ipamorelin pairing for recovery. Any stack moves the week-8 lab repeat from optional to required.
Common mistakes
- Loading the joint because it feels better. The pen eases discomfort before the tissue has remodelled. Follow the rehab plan's pace, not the sensation.
- Chasing the top of the window. 300 mcg twice a day is the house loading dose; 500 mcg is a soft ceiling for an occasional heavy day, not a daily target, and 1,000 mcg a day is never scheduled.
- Mixing up the pens. The 5 mg pen needs almost twice the clicks of the 10 mg pen for the same dose. Check which pen is in your hand before you turn the dial.
- Injecting the same spot every time. Rotate between the injury site and the abdomen, or between nearby sites — repeat irritation is avoidable.
Frequently asked questions
How many clicks is a BPC-157 dose?
On the 10 mg pen, 9 clicks is 300 mcg — the house dose, taken twice a day for weeks 1–4 and once a day for weeks 5–8. On the 5 mg pen, 15 clicks is 250 mcg on the same schedule. One pen holds 300 clicks.
Should I inject BPC-157 near the injury or in the abdomen?
Near the injury site where that is practical and comfortable, otherwise the abdomen a hand's width from the navel — and rotate between the two. For a gut target, the abdomen every time.
How long is a BPC-157 cycle?
Eight weeks: four weeks at two injections a day, then four weeks at one. The dose per injection stays the same; only the frequency changes. Spacing before a repeat cycle is a personalised-protocol decision.
Is 500 mcg of BPC-157 too much?
500 mcg per injection is the house soft ceiling, reserved for an occasional heavy rehab day. The general research window runs 100–1,000 mcg a day, but the house never schedules more than two injections a day or more than 500 mcg in one.
Can I run BPC-157 and TB-500 as separate pens instead of Wolverine?
Yes, and it is the right choice when you want the standalone TB-500 schedule — 2–2.5 mg twice a week for four weeks, then once a week — next to a daily BPC-157 micro-dose. The Wolverine pen is for researchers who want both compounds daily in one click.
