Basics Of BPC-157

Body Protective Compound 157 (known as BPC-157, PL 14736, PL 10, and PLD-116) is a synthetic peptide-based off on naturally occurring peptides secreted by the gut. R 

Most studies reported in BPC-157’s benefits have been in animal models, but per my experience and those with doctors I’ve worked with and their patients, BPC-157 seems to have great potential in humans. 

The Brain-Gut Axis (BGA) controls how the brain, gut, microbiome, and immune system interact.

By stabilizing the BGA, BPC-157 may help with:

  • Alcohol intoxication (acute and chronic) RR
  • Amphetamine toxicity (acutely and chronically), tolerance, and sensitivity RR
  • Diazepam tolerance and dependence R
  • DopamineDepletion R
  • Helpless behavior R
  • Hypothermia and hyperthermia RR R
  • Morphine–induced analgesia R
  • Multiple sclerosis lesions R
  • Muscle weakness and function failure R
  • Parkinson’s Disease RR
  • Seizures (acute and chronic epilepsy) RR R
  • Serotoninsyndrome R
  • Somatosensory disorientation R
  • Tremors RR

Benefits Of BPC-157

BPC-157 can help induce healing of the brain and nerves after a traumatic brain injury (TBI). R R R

BPC-157 repairs the brain after a hemorrhagic stroke and can reduce swelling. R

BPC-157 can protect the brain against hypoglycemic seizures (induced by insulin overdose). R

  1. Protects Against Drug-Induced Damage

BPC-157 can protect the gut, the brain, and the liver against damage induced by NSAIDs. R R R

BPC-157 can prevent aspirin-prolonged bleeding and thrombocytopenia as well as may prevent and rescue adjuvant arthritis. R R

It can protect the gut from ulceration from chemotherapy drugs. R

Cuprizone-induced demyelination is an accepted way to study multiple sclerosis in animal models. R

  1. Restores the Serotonergic Transport System

BPC-157 works on the serotonergic system. R R

BPC-157 significantly reduces the rate of serotonin synthesis in the:

  • Dorsal thalamus R
  • Hippocampus R
  • Hypothalamus R
  • Lateral geniculate body R

BPC-157 increases serotonin synthesis in the nigrostriatal regions:

  • Accumbens nucleus R
  • Lateral caudate R
  • Substantia nigra R
  • Superior olive R

BPC-157 may improve depression and anxiety by its action on serotonin, similar to that of antidepressant drugs (such as imipramine or nialamide). R

For example, in chronically stressed rats BPC-157 could improve their mobility. R

It can also protect the brain against serotonin toxicity as seen in serotonin syndrome via inhibition of 5-HT2A receptor binding. R 

  1. Protects Dopaminergic System

BPC-157 also works on the dopaminergic system (increasing release of dopamine in nigrostriatal regions). R R

It can protect dopamine neurons from toxin-induced damage in models of Parkinson’s Disease (PD). R

It may also protect against dopamine depletion (from stimulant use). R

For example, BPC157 can reduce repetitive OCD symptoms from amphetamine usage. R

It can also prevent haloperidol-induced super sensitivity from amphetamine usage. R

  1. Enhances the GABAergic System

 

BPC-157 acts in favor of the natural homeostasis of the GABA receptors as well as enhancing the GABAergic transmission. R

It can help with anxiety by enhancing GABA neurotransmission. R 

It can also help with withdrawals and tolerance from GABA-based drugs, such as diazepam, making them more effective. R

It also antagonizes alcohol effects, including acute and chronic intoxication. R

  1. Reverses Opioid Tolerance

BPC-157 inhibits action on the opioid system. R R

For example, it can counteract the effects of naloxone and thiopental-induced anesthesia. R R

BPC 157 may also act as an effective paracetamol antidote even against advanced damaging processes induced by extreme overdoses. R

  1. Protects The Heart

BPC-157 can protect the vascular system.

It protects cells against toxin-induced damage. R

It can protect blood vessels from oxidative stress. R

It normalizes both high and low blood pressure. R

It also promotes the formation of new blood via angiogenesis and vasculogenesis. R R

BPC 157 is can also counteract a prolonged QT interval (time between Q and T) from antipsychotic use. R

It can prevent death from high potassium levels (hyperkalemia), and magnesium overdose (hypermagnesemia). R R

BPC 157 successfully prevents and counteracts bupivacaine cardiotoxicity. R

It can also help with arrhythmias from electrolyte imbalances. R

  • Ulcers (Diabetic Ulcers, esophageal) RR

One way it does this is by its ability to increase the activity of the growth hormone receptor. R

It can also increase collagen synthesis. R

BPC-157 has also shown to improve walking post-injury. R

  1. Helps with Allergies And Viruses

BPC-157 may help allergies by preventing anaphylactoid (unrelated to IgE responses) reactions. R

BPC-157 has viral activity on 

  • Cytomegalovirus (CMV)
  • Dengue types 1-4
  • Feline leukemia virus
  • Hepatitis A
  • Herpes
  • Influenza A and ARBO
  • LCM virus
  • Tick-borne encephalitis
  • West Nile fever
  1. May Help Irritable Bowel Disease

Similar to cholestryamine, BPC-157 may help with esophageal reflux. 

One way it does this is by rescuing sphincter dysfunction. 

In rats, higher doses can help with swelling in the gut. 

By repairing ulcers, BPC-157 can help with ulcerative colitis. 

  1. Helps With Ocular Dysfunction

By modulating nitric oxide and cholinergic mechanisms, BPC 157 can counteract atropine-induced mydriasis and L-arginine-induced miosis of the pupil. 

  1. May Help Oral Cavity

BPC-157’s anti-inflammatory effects may be a useful alternative for periodontitis. 

  1. May Help With Urinary Incontinence 

BPC-157 may help reduce stress-induced urinary incontinence. 

My Experience

I originally took BPC-157 for my biliary system and leaky gut but found it to have other systemic effects.

I’ve only taken it orally and sublingually and it has helped me with my sleep, cognition, and food intolerances.

I only need very little doses (~50mcg). 

I’ve also noticed increased histamine in my gut from it (could be part of the repair process).

I will be trying it soon for my blood-brain barrier issues with CIRS (intranasally or injected).

Some people I know have taken it intranasally or corneally (as eye drops) and it has worked. 

Others have reported it significantly helping their workouts, spinal injuries, anhedonia, depression, IBS, anxiety, and Post Orgasmic Illness Syndrome (to name a few).

Here’s my speculation and what I hope to see research in: I would love to know how bpc157 works on tight junctions in the gut and zonulin-1 (ZO-1) or its effect on the microbiome/microbial byproducts and peptides as it seems to reverse a lot of dysbiosis-related disorders.

Where To Get BPC-157

Sources and anecdotes have been discussed on the BPC-157 Research And Support Group on Facebook. 

I’ve tried a few companies and the one I trust the most of course is the patent holder (developed as Bepecin and patented by Diagen), again check out the Facebook group for more on that. R

Alternatives And Synergies

L-Arginine works similarly to BPC-157 in nitric oxide signaling and may be a viable (less strong) replacement. 

It works well with losartan to protect the liver. 

As a drug, it is being developed as Bepecin and is patented by Diagen.  

BPC-157 may synergize with capsaicin for pain and gut protection. 

Dosage

 

BPC-157 can be taken orally or injected and works on nerve healing taken either way. R R

The dose has shown to be from 1μg/kg-10ng/kg in rats. R R

BPC-157 repairs bseems to have more localized effects when injected (which is good for local wound/tendon healing). R

Caveats

BPC-157 has been shown to be safe in clinical trials for inflammatory bowel disease (PL14736), safe for intestinal anastomosis therapy, and is currently in clinical trials for multiple sclerosis. R R R

In most studies, BPC 157 exhibits a rapid, beneficial effect (since the first day) on a cellular level. R

Corticosteroids may reduce BPC-157’s ability to heal muscles. R

As it is proangiogenic, it could enhance the growth of cancer. R

  • The main mechanism of action as a nootropic is that BPC-157 works on angiogenesis (repair of tissue) and less neurogenesis.
  • In tendons, BPC-157 increases fibroblast growth via phosphorylation levels of both FAK and paxillin (dose-dependently). R
  • In collagen repair, BPC-157 stimulates EGR-1 which induces cytokine and growth factor generation and early extracellular matrix (collagen) formation. R
  • EGR-1 also increases its co-repressors such as nerve growth factor 1-A binding protein-2 (NAB2). R
  • BPC-157 can increase decrease B4 (LTB4), thromboxane B2 (TXB2), and myeloperoxidase (MPO) in the serum and inflamed tissues and increase macrophages activity. R
