What are Research peptides?

Peptides are short chains of amino acids that function as signalling molecules in biological systems and are widely studied in laboratory and academic research for their role in cellular communication systems.

How do you ensure the quality of your peptides?

We ensure quality by subjecting every batch of peptides to rigorous third-party HPLC (High-Performance Liquid Chromatography) testing. Each order includes a Certificate of Analysis (COA) detailing purity percentage, molecular weight, and testing methodology. Our peptides consistently achieve 99%+ purity.

How should peptides be stored? .

Lyophilized (freeze-dried) peptides should be stored in a freezer at -20°C (-4°F) for long-term stability. Once reconstituted with bacteriostatic water, peptides should be stored in a refrigerator at 2-8°C (36-46°F) and used within the timeframe specified in the product documentation. Always protect from light and moisture.

What is the purpose of Bacteriostatic (BAC) water?

Bacteriostatic (BAC) water is used in laboratory settings to reconstitute lyophilized peptides under sterile conditions. It is strictly for research purposes and not intended for direct administration.

What is your shipping process?

We offer temperature-controlled shipping to preserve peptide integrity. Orders are processed within 24 hours and shipped in discreet, secure packaging. Tracking information is provided for all shipments, and express shipping options are available for urgent research needs. Delivery times typically range from 1 to 2 weeks, depending on your location.

Which payment methods are accepted?

We accept secure online payments via PayPal, credit cards, Apple Pay, Google Pay, and offline payment methods. All transactions are processed through approved payment gateways for your security.

What is your returns policy?

Due to the sensitive nature of research compounds, we cannot accept returns on opened or used products. However, if you receive a damaged or incorrect item, please contact our support team within 48 hours of delivery, and we will arrange a replacement or refund.
