Peptide Sciences Alternatives
Peptide Sciences posted a shutdown notice on March 6, 2026 and voluntarily ceased operations. Its own notice warns that sites claiming to be successors are fraudulent. Reporting citing Grips Intelligence estimated prior sales around $7.4 million per month, while no public enforcement action names the company.
