Many researchers are looking for the correct BPC-157 dosage for their next experiment.

Like many research peptides, BPC-157 lacks standardized dosing and administration guidelines.

This makes it tough to determine an appropriate BPC-157 dose. Guidance on this front is important, since research has uncovered that BPC-157 may have therapeutic uses like:

  • Improving injury recovery
  • Stimulating wound healing
  • Reducing gut inflammation

In short, BPC-157 has the potential of transforming how we approach healing just about any type of injury.

Below, we detail what you MUST know about administering this peptide, along with a BPC-157 dosage calculator, safety protocols, and potential side effects.

Let's begin!

What Is BPC-157?

BPC stands for “Body Protection Compound”. It is a synthetic pentadecapeptide, which means it is a peptide consisting of 15 amino acids. BPC-157 is derived from endogenous BPC.

This peptide was first discovered in human gastric juices in 1991 and was later isolated by researchers intent on examining its therapeutic properties.

BPC-157 was initially used to prevent stomach ulcers, but researchers noticed several other potential uses for the compound.

Namely, BPC-157 may help improve healing in test subjects [1]:

“Indicatively, BPC 157 improves the healing of the skin wounds, muscle, tendons, ligament, and bone injuries.

Furthermore, considerable recovery of the skin wound and muscle, tendon, ligament, and bone, were observed after severe injury that could not be spontaneously healed.

These healing processes may suggest that BPC 157 may distinctively affect tissue healing.”

How exactly does BPC-157 work in test subjects' bodies?

It is believed that there are multiple mechanisms through which BPC-157 is able to promote healing effects when administered to test subjects.

One of the main mechanisms is through the formation of blood vessels, a process known as angiogenesis.

BPC-157 does this by upregulating vascular endothelial growth factor (VEGF), a protein in the body responsible for stimulating the growth of new blood vessels [2].

It also increases blood flow in the body by increasing the production and release of nitric oxide (NO) [3]. In other words, BPC-157 appears to be a performance-enhancing peptide, but not in the way that researchers might think.

Animal studies have shown that BPC-157 can accelerate the rate of recovery from a wide variety of injuries.

Currently, BPC-157 is not considered an illegal substance and is not banned by international sports organizations, but this may change in the very near future.

As there are very few legitimate human studies available on the effects and safety of BPC-157, it currently remains a research chemical. 

What does the science say regarding the health benefits of BPC-157? Let's take a look. 


Benefits of BPC-157

To be clear, the benefits of BPC-157 are only extrapolations.

The majority of the studies conducted with this compound involved cell cultures and laboratory animals. To date, BPC-157 has yet to pass any clinical trial and is sold exclusively to researchers as a reference material.

Here's a brief guide to past research findings from BPC-157 studies. 

BPC-157 may be neuroprotective

A comprehensive review of BPC-157 completed in 2016 examined the connection between gut health and cognitive disorders in rats.

Specifically, researchers found that BPC-157 affected the rats' brain function in the following ways [4]:

  • Lowered depression in rats facing chronic and unpredictable stress
  • Inhibited symptoms of alcohol withdrawal and alcohol intoxication
  • Repaired damaged nerve branches within the brain

Most interestingly, BPC-157's appears to remain stable in human gastric juice, which is one reason why research interest in this peptide is so high. 

BPC-157 may help treat traumatic brain injury (TBI)

In one animal study, researchers were able to successfully use BPC-157 in mice with traumatic brain injury (TBI).

The 2010 study involved the administration of BPC-157 to mice with head injuries [5].

The group of mice that received the strongest dose of BPC-157 (10 mcg/kg) had a higher survival rate compared with mice in the placebo group.

Furthermore, the post-injury damage done to the rats 24 hours after administering BPC-157 was significantly less than what was observed in the placebo group. 

BPC-157 may improve gastrointestinal health

BPC-157 has been found to impact gastrointestinal health in several ways.

It can counteract complications brought about by inflammatory bowel disease (IBD), lower both acute and chronic inflammation within the gut, and reverse short-bowel syndrome following resection of the intestine [6].

Additionally, BPC-157 can counteract colon damage and inhibit the formation of ulcers.

BPC-157 helps reverse the damage done by drug-induced toxicity

An unusual benefit of BPC-157 is that it appears to treat the damage and adverse side effects brought about by commonly used drugs.

For instance, nonsteroidal anti-inflammatory drugs (NSAIDs) can be toxic when taken in high doses. The toxic effects often include seizures, respiratory depression, and hypotension.

In 2013, scientists found that BPC-157 helps counteract the toxic side effects brought about by NSAIDs [7]. There were no reported toxicity events when extremely high doses of BPC-157 were used.

A similar observation was observed in a rat study where BPC-157 was able to reduce the degree and severity of the damage done by methamphetamine-induced neurotoxicity [8].

BPC-157 has anti-inflammatory properties

A 2009 experiment involving rats with periodontitis (a condition where the gums are infected and heavily inflamed) found that rats administered BPC-157 did not have their blood circulation negatively affected.

Most importantly, BPC-157 exhibited anti-inflammatory effects while also healing and preserving the gum tissues [9]. 

It must be stressed that the results from the above-cited animal studies cannot be extrapolated to humans. However, researchers may consult these findings when designing future BPC-157 experiments.

BPC-157 Dosage Guide | What Researchers MUST Know

Researchers looking for a BPC-157 dosage calculator will note that this peptide has no recommended dosage in human test subjects. Studies on BPC-157 in human subjects are lacking and this merits further research.

So, how might BPC-157 be dosed in future experiments?

While dosages used in laboratory animal studies cannot be transposed to clinical studies, some researchers have estimated that the BPC-157 doses administered to rats – 10 mcg/kg – would translate to 0.73mcg/lb (1.6mcg/kg) for humans. This suggests that a 144 mcg dose of BPC-157 could be administered to a 90 kg test subject [10, 11].

Aside from this estimate, there are no official or published figures to indicate the dosage at which BPC-157 should be administered to research subjects.

However, anecdotal reports suggest similar or slightly higher dosages for injury recovery and healing research which includes one to three doses of 250mcg BPC-157 daily for a 4-week trial.

Here is a sample dosage guide based on these suggestions:

  • Dosage: 500-750mcg/daily for the first 2 weeks, 250-500mcg/daily for weeks 3-4.
  • Frequency: Daily.
  • Duration: Administer for up to four weeks.
  • Notes: Dosage should be within the range of 0.9-1.8mcg/lb.

Given that there is strong interest in the application of BPC-157 in test subjects, we can summarize the main research findings below. 

BPC-157 For Beginners

Researchers new to BPC-157 experimentation should be aware that data from animal studies indicate the most effective way to administer this peptide is intramuscularly (in the muscle). While BPC-157 can be injected subcutaneously, animal studies suggest that intramuscular administration is more effective. 

There is no convincing evidence to show whether BPC-157 acts systemically or locally, but data from a rat study indicated that it acts locally [9]. This suggests that BPC-157 should be administered close to the site of injury for best results, but further research is warranted.  

In terms of safety, researchers should abide by established protocols when administering BPC-157. This includes using sterile needles, having high-quality bacteriostatic water to reconstitute the peptide, and storing the solution in the refrigerator when it is not being used.

Researchers are advised to avoid oral solutions and transdermal patches, as they are not as effective as injections.

How to Reconstitute BPC-157 BPC-157

is available for research as lyophilized powder that needs to be reconstituted before use. Here is a short 4-step guide on how to reconstitute BPC-157:

Step 1: Gather the necessary items.

  • Bacteriostatic water
  • Insulin syringes
  • Alcohol pads
  • Sterile storage vial 3cc syringe with needle

For your convenience, offers research kits containing all the above essentials, excluding the peptide powder.

Step 2: Determine the right amounts.

Utilize the provided calculator to help determine the volume of bacteriostatic water required to reach your target concentration with the BPC-157 powder.

This tool will also guide you in dosing BPC-157 based on your chosen syringe type.

Step 3: Mix bacteriostatic water with the BPC-157 powder.

With the 3cc syringe and needle, draw an air volume equivalent to the bacteriostatic water needed for your mixture. Pierce the needle into the bacteriostatic water vial and release the air, preventing a vacuum effect. Subsequently, extract the appropriate volume of diluent.

Angle the needle into the BPC-157 vial and gently press the plunger, allowing the water to flow down the vial's interior. After emptying the syringe, remove it.

Step 4: Let the peptide dissolve.

Avoid shaking or tapping the vial. Simply let it sit for 10 to 20 minutes, allowing the BPC-157 peptide to dissolve fully. If undissolved particles remain, you can gently roll the vial between your hands to finalize the reconstitution.


BPC-157 For Healing

Researchers interested in experimenting with BPC-157 for healing should have a full understanding of the three phases of the healing process [12]:

  • PHASE I: The Inflammatory Phase (Days 1-5) Platelets aggregate and trigger the release of pro-inflammatory mediators. A clot is formed around the site of injury to stop further bleeding from occurring, which is later broken down by cellular compounds known as macrophages.
  • PHASE II: The Proliferative Phase (Days 5-14) Healthy cells are attracted to the site of injury, and the body stimulates angiogenesis to ensure that a sufficient amount of oxygen and nutrients are transported to the site.
  • PHASE III: The Remodeling Phase (Days 14+) The cells that were used to heal the wound are no longer needed. Through a form of cellular death called apoptosis, they are removed and a scar with properties resembling the original tissue is formed.

With this understanding in mind, let's examine the types of injuries in laboratory animal that BPC-157 has been shown to treat:

  • BPC-157 cream was used to heal burn wounds in injured mice [13]
  • In rats, BPC-147 was successfully used to heal skeletal muscle injuries and restore full functionality to the muscles being healed [14]
  • BPC-157 was used to heal spinal cord injury in rats; consistent clinical improvements were observed spinal function was restored [15]
  • BPC-157 was used to accelerate the speed at which injured tendons were healed in rats [16]

These findings indicate that BPC-157 may offer benefits in test subjects and may merits further research.

BPC-157 For Muscle Growth

There is very strong research interest in the application of BPC-157 to improve body composition, with many researchers theorizing that it may minimize body fat accumulation and maximize lean muscle gains. 

As studies on BPC-157 in human subjects are lacking, there are no published figures to indicate the optimum BPC-157 dosage for muscle growth. The only study demonstrating any kind of weight gain was an animal study in which BPC-157 was used to cure short bowel syndrome in rats [17].

Whether these findings can be replicated in human test subjects has yet to be examined, potentially highlighting a fruitful direction for future research. 

BPC-157 For Hair Growth

Laboratory animals studies have shown that BPC-157 improves blood flow uniformly, leading some researchers to speculate that it may promote hair growth [18]. There is currently no published research involving either animal or human test subjects to support these claims. 

Researchers interested in exploring BPC-157 for hair growth may consult the relevant studies to determine dosage and methods of administration [9].

In summary, the purported benefits of BPC-157 in humans are under-researchers. This indicates that further experimentation is required before drawing conclusions about this peptide's effects.

Thymosin Beta-4 and BPC-157?

There is currently strong interest among peptide researchers in the purported synergistic effects of BPC-157 and TB-500.

TB-500 is the synthetic version of Thymosin Beta-4, a protein found in every single tissue of the body.

Laboratory animal studies have shown that TB-500 may help regenerate various types of tissues and serve other therapeutic purposes such as treating strokes, cardiac damage, and stasis ulcers.

There are two crucial differences between these peptides:

  • TB-500 is systemic in its effects, whereas BPC-157 is localized
  • TB-500 has shown more potential for treating muscle injuries in test subjects while BPC-157 appears better suited to treating inflammation

In past studies, TB-500 has been administered twice a week at 2-4 mg per dose and has been injected either subcutaneously or intramuscularly.

Researchers intent on exploring the potential synergistic effect of TB-500 and BPC-157 may consider using this blend of TB-500 and BPC-157 for their next experiment. 


BPC-157 Dosing | Verdict

Hopefully, researchers interested in calculating the optimal BPC-157 dosage for their next study have found this A-Z guide instructive and informative.

As discussed above, studies on BPC-157 overall are notably lacking and this merits further research, including research into the risk-benefit tradeoff with respect to potentiating angiogenesis over varying durations of therapy.

Despite the many purported BPC-157 benefits observed in laboratory animal studies, little is known about this peptide's effects and side effects in humans, or the dosage at which it should be administered.

Researchers planning to explore BPC-157 may consult Peptide Sciences for further guidance and information.
