BPC-157 Dosage by Weight: What the mcg/kg Range Really Means
What Is the BPC-157 Dosage by Weight Range?
Research protocols scale BPC-157 to body mass at 5 to 10mcg per kilogram. An 80kg subject (176lb) sits at 400 to 800mcg. A 100kg subject (220lb) sits at 500 to 1,000mcg. That range is wide because it was inferred from animal work, not settled by human trials.
Scaling matters. A 60kg frame and a 110kg frame are not the same. Tying an amount to body mass is standard across medicine, and a flat number ignores it. Below is the chart, where its numbers really came from, and the point at which a tool beats a table.
BPC-157 Dosage Chart by Weight: 5 to 10mcg/kg
| Bodyweight | Low end (5mcg/kg) | High end (10mcg/kg) |
|---|---|---|
| 60kg (132lb) | 300mcg | 600mcg |
| 70kg (154lb) | 350mcg | 700mcg |
| 80kg (176lb) | 400mcg | 800mcg |
| 90kg (198lb) | 450mcg | 900mcg |
| 100kg (220lb) | 500mcg | 1,000mcg |
| 110kg (243lb) | 550mcg | 1,100mcg |
The arithmetic is one step. Multiply your mass in kilograms by 5, then by 10. Pounds convert by dividing by 2.205, so 200lb becomes roughly 90.7kg and reads off the 90kg row. Landing between rows changes nothing. An 84kg reader (185lb) gets 420mcg at the bottom and 840mcg at the top. For anything less tidy than that, the BPC-157 dosing calculator does it instantly and shows its working.
Why Does the Range Come From Rodent Studies?
Because there is almost no human data. Most charts leave that out. It changes how much trust the numbers earn.
A 2025 systematic review screened 544 articles published between 1993 and 2024. After removing duplicates it kept 36 studies. Of those, 35 were preclinical and 1 was clinical (Vasireddi et al. 2025). The same review graded the evidence at Level IV to V, the lowest tiers available, and found no formal clinical safety data. The one human study was a small look back at knee pain notes. Relief was reported by 14 of 16 patients. There was no control group (Lee et al. 2021). A separate review of patents and papers found a broadly good animal safety record. It also said plainly that no regulator has approved the compound (Jozwiak et al. 2025). A critical review of tendon and muscle healing reached the same verdict from another angle: consistent animal signals, unconfirmed in people (Gwyer et al. 2019).
So treat 5 to 10mcg/kg as a published reference band, nothing firmer. It is not a proven safe window. No regulator has set a ceiling. Anyone selling it as a precise dose is claiming more than the research shows. Our BPC-157 complete guide covers the underlying mechanism work in full.
How Do You Turn a BPC-157 Dosage by Weight Into Syringe Units?
Your dose in mcg means nothing until you know how strong the vial is.
Strength comes first. A 5mg vial in 2mL of water gives 2,500mcg/mL. Divide your dose by that, then multiply by 100. A 400mcg dose reads as 16 units on a U-100 barrel. An 840mcg dose reads as 33.6 units. Round to a mark your syringe really shows. Pick one rounding direction and keep it, so the amount does not creep over time. The mixing side is covered in our peptide reconstitution chart, and timing and frequency sit in the BPC-157 dosing protocol.
Who Should Avoid BPC-157 Entirely?
Two groups deserve a flat stop rather than a scaled dose, and neither one is about body mass.
The first is anyone on blood thinners. BPC-157 is studied for its effect on new blood vessel growth. No human data exists on that mix at all. Silence is not the same as safety.
The second is anyone with diabetes or on blood sugar medication. Again, no human trial has tested that pairing. The same caution holds with an active cancer. Repair pathways do not choose which tissue they help. In all three cases the next step is a qualified clinician, not a chart.

Purity decides whether any of this maths holds. An underfilled or dirty vial makes every row above worthless. Check our recommended sources page, which lists only suppliers publishing independent third-party certificates of analysis.
