Applications

Best
suited for

Thymosin Beta-4

Post-Surgery Recovery

Accelerates healing of surgical wounds and reduces post-operative inflammation and scarring

Chronic Wound Management

Helps pressure ulcers, venous stasis ulcers, and other slow-healing wounds progress faster

Tissue Regeneration

Supports repair of damaged tissues from injury, burns, or degenerative conditions

BPC-157

Tendon and ligament injuries

Sprains, strains, tears, tendinitis - BPC-157 accelerates collagen synthesis and tissue repair

Gut healing

IBS, leaky gut, ulcers, inflammatory bowel conditions - derived from gastric juice, it has a natural affinity for digestive tissue

Muscle injuries

Strains, post-workout recovery, chronic muscle issues - promotes angiogenesis and growth factor expression

Joint problems

Arthritis support, joint pain, cartilage issues - anti-inflammatory and regenerative properties

Post-surgical recovery

Accelerating healing after procedures - works systemically to enhance the body's repair mechanisms

& evidence

Thymosin Beta-4

Evidence Level

Research compound

Safety Overview

Thymosin Beta-4 is a naturally occurring peptide found in all cells and body fluids in the human body. Clinical trials have demonstrated excellent safety even at very high doses. IV studies showed doses up to 1260 mg were well tolerated with no serious adverse events.

Contraindications

  • xActive systemic infections
  • xSevere immunosuppression
  • xHypersensitivity to thymosin or any component
  • xPregnancy (insufficient safety data)

BPC-157

Evidence Level

Strong preclinical (extensive animal studies)

FDA Status

Research compound

Safety Overview

BPC-157 is a gastric pentadecapeptide with strong preclinical evidence from extensive animal studies spanning over 25 years of research. Critical limitation: BPC-157 has NOT completed Phase 3 human clinical trials. No FDA approval exists. Safety data comes primarily from rat and mouse studies, with only limited Phase 1-2 human data. Animal studies show no toxicity at therapeutic doses, but human data is insufficient for regulatory approval. The peptide is unregulated, and no standardized manufacturing or quality control requirements exist for research compounds. Individual responses may vary significantly, and serious medical supervision is essential before use, particularly if you have gastrointestinal conditions, take medications, or have pre-existing medical conditions.

Contraindications

  • xPregnancy
  • xBreastfeeding
  • xActive cancer
  • xHistory of cancer
