tiers

Pentadecapeptide (BPC Analog)

TB-500

starting

2-2.5 mg

Twice weekly

4-6 weeks

Start here to assess your tolerance and response. Many people see good results at this dose. Split your weekly dose into two injections spaced 3-4 days apart (like Monday and Thursday).

standard

4-5 mg

Twice weekly (split into 2-2.5 mg doses)

4-6 weeks

The most commonly used protocol for moderate injuries. Your total weekly dose is 4-5 mg, split into two injections. This is the sweet spot where most users see significant healing benefits.

advanced

5-10 mg

Twice weekly (2.5-5 mg per injection)

4-8 weeks

Higher doses for severe or stubborn injuries. Some protocols use a loading phase of higher doses for 1-2 weeks, then drop to maintenance. Work with a provider for doses above 5 mg weekly.

Applications

Best
suited for

Pentadecapeptide (BPC Analog)

Recovering from sports injuries or muscle strains

Pentadecapeptide (BPC Analog) is particularly well-suited for individuals focused on recovering from sports injuries or muscle strains. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.

Supporting post-surgery tissue repair

Pentadecapeptide (BPC Analog) is particularly well-suited for individuals focused on supporting post-surgery tissue repair. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.

Accelerating tendon and ligament healing

Pentadecapeptide (BPC Analog) is particularly well-suited for individuals focused on accelerating tendon and ligament healing. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.

Improving overall recovery speed

Pentadecapeptide (BPC Analog) is particularly well-suited for individuals focused on improving overall recovery speed. Research and clinical experience suggest meaningful benefits in this area when used as part of a comprehensive treatment approach.

TB-500

Athletes Recovering from Muscle Injuries

If you've pulled a hamstring, strained your back, or torn a muscle, TB-500 helps accelerate the healing process by promoting cell migration to the injury site and supporting new blood vessel growth. It's especially useful for injuries that just won't seem to fully heal.

Tendon and Ligament Problems

Tendons and ligaments are notoriously slow healers because they have poor blood supply. TB-500 promotes angiogenesis (new blood vessel formation) and helps repair these stubborn connective tissue injuries—think Achilles tendonitis, tennis elbow, or rotator cuff issues.

Post-Surgical Recovery

After surgery, your body needs to repair a lot of tissue quickly. TB-500 supports wound healing, reduces inflammation, and may help minimize scar tissue formation. Some protocols use it alongside traditional recovery to potentially speed up the healing timeline.

Chronic Inflammation and Slow Healers

Some people just heal slowly—whether due to age, diabetes, or other factors. TB-500 helps regulate the inflammatory response and promotes the cellular processes needed for tissue repair. It essentially tells your body to focus healing resources where they're needed most.

Safety
& evidence

Pentadecapeptide (BPC Analog)

Evidence Level

Moderate human trials (Phase 1-2)

FDA Status

Research compound

Safety Overview

BPC-157 analogs show favorable safety in animal toxicity studies with LD50 >1000 mg/kg (oral, rats). No serious adverse events in limited clinical case reports; mild local injection site effects observed. Gastroprotective mechanism suggests low systemic toxicity; rapid hepatic metabolism limits systemic exposure. Preclinical studies show no mutagenicity, carcinogenicity, or teratogenicity; reproductive safety appears favorable.

Contraindications

  • xActive cancer or high cancer risk
  • xPregnancy or breastfeeding
  • xKnown hypersensitivity to peptides

TB-500

Evidence Level

Moderate human trials (Phase 1-2)

FDA Status

Research compound

Safety Overview

TB-500 has shown a good safety profile across preclinical studies and limited human research. It's a fragment of thymosin beta-4, a naturally occurring protein in your body involved in healing. Most side effects are mild and transient, primarily injection site reactions. However, large-scale clinical trials are still needed to fully establish its safety profile in humans.

Contraindications

  • xPregnancy or planning to become pregnant
  • xCurrently breastfeeding
  • xActive cancer or history of cancer
  • xKnown allergy to peptide components
  • xChildren and adolescents
