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 systems interact.

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

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

Benefits Of BPC-157

1. Repairs The Brain

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

2. 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

3. Restores The SerotonergicTransport 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 

4. 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 supersensitivity from amphetamine usage. R

5. 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. 

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

6. 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

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

9. 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

10. May Help Irritable Bowel Disease

Similar to cholestyramine, 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. 

11. Helps With Ocular Dysfunction

13. 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.

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

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

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