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
Thymosin Beta-4
Evidence Level
Moderate human trials (Phase 1-2)
FDA Status
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)
