BPC-157 Dosage: What the Research Reports

What is the researched BPC-157 dosage range?

Most BPC-157 dosage figures come from animal studies, and no standard human dose has been established (Sikiric et al., Gut and Liver 2020; PMC7096228).

BPC-157 is a synthetic pentadecapeptide studied mostly in preclinical (animal) research. The most cited review of that work describes many rodent experiments and states that human evidence is limited (Sikiric et al., Gut and Liver 2020; PMC7096228). Because of that, the numbers repeated on forums are usually taken from animal protocols and then scaled by hand, not read off a finished human trial.

That distinction matters for anyone searching "bpc-157 dosage." There is no clinically validated human dose to quote. What exists is a body of animal data plus generic conversion math, and both need a qualified clinician to interpret for any individual.

Why is human BPC-157 dosing data so limited?

Because no large completed human trial has defined a standard dose, published BPC-157 dosing rests on animal models (Sikiric et al., Gut and Liver 2020; PMC7096228).

The review that anchors most BPC-157 discussion is built on rodent studies covering several tissue and organ models (Sikiric et al., Gut and Liver 2020; PMC7096228). Preclinical work like this is useful for signals and mechanisms, but it does not set a human dose, a schedule, or a safety margin. What limited human work exists is thin: an early Phase 1 tolerability report and a Phase 2 study of a BPC-157 enema formulation (labeled PL-14736) for ulcerative colitis were presented, but the full trial results were not published in a peer-reviewed clinical journal, which makes independent evaluation hard (see References). Human pharmacokinetics, meaning how the body absorbs, distributes, and clears the peptide, are not well characterized in the published literature.

So when a source states a confident "human dose," ask where the number came from. In most cases the honest answer is an animal study plus an assumption.

What doses did BPC-157 studies actually report?

Across the Sikiric group's animal work, a research dose near 10 mcg/kg body weight is the figure reported most often, with activity described even at much lower amounts such as 10 ng/kg, and several routes were used (Sever et al., European Journal of Pharmacology 2019; PMID 30690000; Sikiric et al., Gut and Liver 2020; PMC7096228).

The figures below describe what published research reported. They are not a recommendation, a protocol, or instructions for use, and any personal dose belongs with a qualified clinician.

Note the units. These are amounts scaled to body weight in animals (nanograms and micrograms per kilogram), not a fixed daily amount for a person. Reading them as a human dose is exactly the step the data does not support.

How does BPC-157 reconstitution math work?

Reconstitution is arithmetic: powder mass divided by water volume gives the strength, and that strength tells you how many micrograms sit in each unit on a syringe.

Peptides ship as a freeze-dried powder and are mixed with bacteriostatic water before use in a lab setting. The math only tells you the strength of the solution. It does not tell you how much to use, and it is shown here as reference, not as a dose recommendation.

A U-100 insulin syringe reads 1 mL as 100 units. So once you know the strength in mcg per mL, you divide by 100 to get mcg per unit.

These are reference conversions to help you read a label. They do not set a target amount. Whether any amount is appropriate, and what that amount would be, is a clinical decision. For the general handling steps, see the [reconstitution guide](/reconstitution).

Can animal BPC-157 doses be converted to a human dose?

Not reliably on your own, because species differ in size, metabolism, and route, and human data is limited (Sikiric et al., Gut and Liver 2020; PMC7096228).

Animal-to-human dose translation is not simple multiplication. It depends on factors that the current BPC-157 literature does not settle for people, including how the peptide is absorbed and cleared in humans. A number that looks safe in a rat model does not carry a guarantee in a person, and the review is clear that human evidence remains thin (Sikiric et al., Gut and Liver 2020; PMC7096228).

That is why this page routes the actual decision to a qualified clinician. The published figures inform a conversation; they do not replace one. For the safety picture, see [BPC-157 side effects](/bpc-157-side-effects).
