BPC-157 Dosage Guide — Research-Based Reference for 2026

The BPC-157 dosage is one of the most popular topics related to peptides, yet no definitive dosage approved by any regulatory authority is known at present. All dosages of BPC-157 provided by various forums and vendors are based on only a few rodent studies published over the last thirty years. We decided to summarize the aforementioned dosages in this document, explain where each dose came from, and show that it is not so easy to convert a study on rats to studies on humans.

BPC-157 Dosage Chart - Study Data at a Glance

The data in the table below was collated from rat studies published in peer-reviewed journals. Each row feature its citation from PubMed, where you can check the numbers directly. It is the only BPC-157 dosage chart that limits itself to peer-reviewed sources.

Subcutaneous Doses in Rat Models

Although subcutaneous injection is the most talked-about route in the peptide forums, most of the available literature on rats uses IP. IP involves an injection into the peritoneal cavity, which has a different pharmacokinetic profile than subcutaneous injections. Cerovecki et al. (PMID 20225319) used both 10 mcg/kg and 10 ng/kg dosages and reported an improvement in mechanical properties with the higher dosage. Injection into the local wound site does not fit the procedure of self-injection well, as seen in Chang et al.'s ligament study.

Oral Doses in Rat and Mouse Studies

The dosing of the BPC-157 component is thoroughly discussed in the literature on gastroprotection. Sikiric et al. 1999 (PMID 9920181) administered 10 mcg/kg by oral gavage and by IP injection in the same study design, reporting protective effects on rat gastric mucosa via both routes. Sikiric et al. 2018 (PMID 29879879) surveys the broader evidence and notes oral activity across multiple models.

How Reconstitution Math Works

When a scientist buys lyophilized BPC-157 vials, he must always add the bacteriostatic water for the administration. It's the water used that defines the concentration, and it's the concentration that defines how many units will the syringe have for a particular microgram dose.

Milligrams, Micrograms, and Syringe Units

One milligram is equivalent to 1,000 micrograms. In general, an ordinary insulin syringe bears a volume of 1 mL that has been divided into 100 units, where one unit is equal to 0.01 mL. When you add 2 mL of bacteriostatic water to the 5 mg vial, you will get 2,500 mcg of concentration in 1 mL, or 25 mcg per unit. This conversion is just the mathematics and does not give any instructions on how the drug should be applied.

Concentration Formula Walkthrough

The concentration formula is: Concentration (mcg/mL) = Total peptide (mcg) divided by Total water (mL). In the case of a 10 mg vial reconstituted in 2 mL of bacteriostatic water, therefore: 10,000 mcg divided by 2 mL = 5,000 mcg/mL. Hence, every 0.01 mL syringe unit will have 50 mcg of peptide within it. Our peptide reconstitution calculator performs this math automatically for any vial size and water volume.

Comparing BPC-157 Sources by Price Per mg

The price varies widely among vendors. Vial sizes also vary, so the best metric for comparison is the price per milligram peptide. The retail prices were obtained from two vendors that are often mentioned in peptide communities.

PeptideGod vs Real Peptides - 2026 Pricing

The pricing for BPC-157 at PeptideGod is set at $34.95 per vial. The quantity is absent from the product information, and no analytical report is available. The same product by Real Peptides is priced at $43.20, providing 10 mg of BPC-157 that possesses HPLC purity greater than 99% and so can be verified with a certificate of analysis provided on the site. More so, the company claims that mass spectrometry tests confirmed the results. While it is impossible to make a complete comparison between the costs charged by PeptideGod and Real Peptides only by looking at the price per mg of the peptide, the raw price alone cannot be sufficient since the purity of BPC-157 available from PeptideGod is yet to be known for a proper calculation.

Another product is a combination of BPC-157 and TB-500 offered for $59.95 by PeptideGod. Blended peptide products raise even more questions related to the amount and stability of the peptides that were blended. For detailed comparison, please go and check out our best BPC-157 page.

What the Research Does Not Show

If you focus solely on what the studies say, you could develop an undeserved sense of confidence. The holes in the evidence base are equally vital to understand.

No Human Trials With Dose-Response Data

As of now, there are no human clinical trials in the literature that compare different doses of BPC-157 to assess effectiveness and safety. Since dose-response data is an essential component of clinical pharmacology, it is worth noting BPC-157 dose-response data is totally absent in humans. The dosage of 10 mcg/kg determined in rodent studies is not validated in humans either.

Translation From Rodent to Human Is Not Linear

Allometric scaling equations have been derived to convert doses in animals into human- equivalent doses based on body form and size. More recently, the FDA published a guidance document on this subject employing the method of body surface area conversion, not weight-based calculation. So a dose of 10 mcg/kg in a rat cannot be equated with a dose of 10 mcg/kg in a human body. The difference in metabolic rate, making up a particular body weight and body shape, and distribution of organs must be remembered in this respect. We emphasized this point since there are a lot of posts discussing various protocols of BPC-157 on the internet, which miss this important information and simply use weight-based calculations for applying doses in rats to humans.
