The plain-English version
Most people run 250 to 500 micrograms (a tiny amount, less than a drop) per day for about four to six weeks. Inject just under the skin (subQ, the easy fat-pad shot) near the injury when you can. Then stop and reassess. Always with a doctor.
Route: subcutaneous injection, oral capsule. Evidence tier for the dose: Strong animal evidence. Decades of consistent animal evidence; human RCTs are sparse but the mechanism is well-established.
The dose at a glance
| What's typical | What's the max in research |
|---|---|
| Starting dose: 250 mcg per day for the first 3 to 5 days. Some clinicians start at 200 mcg to test tolerance. | Max observed in research: Animal studies have used the equivalent of roughly 1,000 mcg per day in humans without clear added benefit. More is not better. (Sikiric et al., review of body-protection-compound research) |
| Maintenance dose: 250 to 500 mcg per day, usually split into two shots (morning and evening) or one shot near the injury site. | |
| Frequency: Daily, often split AM and PM. Some protocols use a single daily injection near the injury site. | Half-life: Roughly 4 hours from a subQ shot, which is why splitting AM and PM is common. Oral form has a much shorter window in the gut itself. |
Titration (how to ramp the dose)
Most users skip formal titration (slow ramp-up). If you have a sensitive system, start at 200 mcg, hold 3 to 5 days, then move to 250-500 mcg.
Cycle length and time off
On cycle: 4 to 6 weeks of daily use is the standard cycle.
Off cycle: At least 4 weeks off after a 4-6 week cycle. Some users do longer breaks (8-12 weeks) before repeating.
Timing notes: Time of day does not matter much. Some users find evening shots help with sleep-time recovery. Oral capsules work best on an empty stomach for gut-targeted use.
What's commonly prescribed (per published protocols and clinical write-ups)
Compounding pharmacies in the US typically dispense 5mg vials of lyophilized (freeze-dried, shelf-stable) BPC-157. Telehealth scripts usually read '250-500 mcg subQ daily x 4-6 weeks.' Sports-medicine clinics will sometimes do localized injections in the affected area instead.
Source: prescribing labels, published protocols, and clinical write-ups. We have not independently tested each prescriber pattern.
Reconstitution (mixing the vial)
Lyophilized 5 mg vials reconstitute (mix back into liquid) with exactly 2 mL of bacteriostatic water (sterile water with preservative, the kind compounding pharmacies sell for reconstituting peptides). At 5 mg per 2 mL, every 0.1 mL on the syringe equals 250 mcg. If your pharmacy filled the vial with a different volume, recalculate from the mg/mL printed on your vial label - not from this page. Store reconstituted vial in the fridge, use within 30 days.
Reconstitution = mixing freeze-dried (lyophilized) powder with bacteriostatic water (sterile water with preservative) so you can draw a dose into a syringe.
Products on the market
BPC-157 is sold in three main forms. Each has different bioavailability (how much actually reaches your bloodstream) and different price-per-effective-dose math. Quality varies wildly between vendors.
Oral capsule
Best for gut healing (the peptide acts directly on gut lining). Convenient. Lower bioavailability than injection for systemic effects (joints, tendons), but enough to drive results based on user reports.
Things to check
- COA (Certificate of Analysis - the lab report showing what's actually in the capsule)
- Whether the product is pure BPC-157 or a blended formula
- Storage conditions and shelf life
Subcutaneous injection (subQ - the under-the-skin shot)
Standard biohacker form for joint, tendon, and systemic recovery. Higher bioavailability than oral. Requires reconstitution with bacteriostatic water (sterile water with preservative).
Things to check
- Lyophilized (freeze-dried) powder in a sealed glass vial
- 5mg standard size
- COA published by the vendor
- No blends - pure BPC-157 only
Topical cream or spray
Localized application near a joint or skin issue. Lowest bioavailability. Some users combine with oral or injection rather than relying on topical alone.
Things to check
- Concentration (mg per mL or per pump)
- Whether the carrier is well-formulated for skin penetration
- Reputable compounding pharmacy as the source
We are evaluating BPC-157 vendor partnerships. We have not yet endorsed a specific vendor. When we do, it will be disclosed as an affiliate relationship per FTC rules.
Drug interactions to watch
- No major drug interactions documented in human studies (limited data overall).
- Animal data suggests it may interact with NSAID-induced gut damage (likely protective, not harmful).
- If on blood thinners, talk to your prescriber about the new-blood-vessel growth mechanism.
Who should not take this (contraindications)
- Active cancer (the angiogenesis mechanism could in theory feed tumors; no human data either way).
- Pregnancy and breastfeeding (no safety data).
- Known hypersensitivity to the peptide (rare but documented).
Common side effects
- Mild nausea in the first few days (more common with oral form).
- Injection-site soreness or small bruising.
- Headache or fatigue in the first week (usually fades).
Serious side effects (call a doctor)
- No serious side effects have been reported in published research, but the human data is thin.
- Allergic reaction (hives, swelling) is rare but stop and call your doctor.
What to monitor while you're on it
- Reassess injury pain and function at 4 weeks. If nothing has changed, stop.
- Track injection-site reactions in a notes app.
- If using long-term, ask your doctor about CBC and basic metabolic panel every 3 months.
How to stop
Just stop at the end of the cycle. No formal taper needed. The peptide clears in days.
Where this dosing comes from
- Sikiric et al., review papers 2018 and 2020 on Body Protection Compound dosing in animal models
- Gwyer et al., 2010 (Achilles tendon model)
- US compounding pharmacy formularies (Tailor Made, Empower, Strive)
- Reddit r/Peptides community consensus dosing posts (treated as anecdotal but consistent)
Where these doses come from
These doses extrapolate from animal studies and biohacker community consensus. No human RCTs at these specific doses. We have not personally tested every protocol on this page.
Always work with a real prescriber. Don't self-prescribe.
Safety reminder: None of this replaces a doctor. Peptides are gray-market in the US for most uses. Talk to a real prescriber before you change anything.
