Quality is the cornerstone of PeptidesFarma. Every batch undergoes rigorous High-Performance Liquid Chromatography (HPLC) testing to ensure a purity level of 99% or higher. We provide third-party Certificates of Analysis (COAs) for every product, giving you complete transparency into what you are receiving.

Yes. For optimal stability, we recommend storing lyophilized peptides at -20C. Once reconstituted, store at 2-8C and use within 30 days. Always protect from light and moisture.

All our peptides are synthesized in GMP-compliant facilities within the United States. We work with certified manufacturers who follow strict pharmaceutical-grade protocols.

We use insulated packaging with gel ice packs for all shipments. Orders are processed same-day and shipped via priority carriers to minimize transit time and maintain product integrity.

A Certificate of Analysis (COA) is a document that details the testing results for each batch, including purity, identity confirmation, and endotoxin levels. COAs are available on each product page and included with every order.

Due to the nature of research compounds, we cannot accept returns on opened products. However, if your order arrives damaged or incorrect, contact us within 48 hours and we will reship at no charge.
