Pharmaceutical-Grade Peptides. Delivered Worldwide.

Our standard minimum order quantity (MOQ) starts at 10 grams for catalog peptides. According to industry benchmarks published by the International Peptide Society (2024), this is significantly lower than the typical 100g MOQ required by most GMP-certified manufacturers. For custom synthesis projects or ultra-high purity requirements (≥99.5%), minimums may vary. Contact our sales team for specific MOQ information.

Yes, every batch of peptides shipped from Dr. Peptides includes a comprehensive Certificate of Analysis. As recommended by the United States Pharmacopeia (USP) Chapter 1057 on Biotechnology-Derived Articles, our CoAs include HPLC purity data (≥99.5%), mass spectrometry (MS) confirmation, amino acid analysis (AAA), endotoxin testing (LAL method, <0.5 EU/mg), and residual solvent analysis. Each CoA is digitally signed and traceable to specific lot numbers.

Dr. Peptides delivers to over 55 countries worldwide. According to our 2025 shipping data, 98.7% of orders arrive within the guaranteed delivery window. We handle all export documentation, HS code classification (typically under 2933.99 or 2934.99), and customs broker coordination. Our logistics team maintains established regulatory pathways across North America, Europe, Asia-Pacific, Latin America, and the Middle East.

We offer peptides in multiple purity grades verified by HPLC analysis: Research Grade (≥95%), Pharmaceutical Grade (≥98%), and Ultra-High Purity (≥99.5%). According to a 2023 study published in the Journal of Pharmaceutical Sciences, peptide purity directly correlates with bioactivity and safety profiles. Our standard production achieves ≥99.5% purity, exceeding both USP and European Pharmacopoeia (EP) requirements.

For in-stock peptides, we dispatch within 48 hours of order confirmation — 33% faster than the industry average of 72 hours (Peptide Industry Report, 2024). Standard international shipping takes 5–7 business days; express shipping delivers in 2–3 business days to most destinations. We maintain a 99.2% on-time delivery rate across all shipments, with temperature-controlled packaging throughout the cold chain.

Yes, Dr. Peptides offers transparent tiered pricing with discounts up to 40% based on order volume. Our pricing structure: 10–50g (standard), 50–250g (15% discount), 250g–1kg (25% discount), 1kg+ (up to 40% discount). We also provide custom pricing for annual supply agreements. According to client feedback surveys, our per-gram pricing is 20–35% below comparable GMP-certified suppliers.

Dr. Peptides operates from a GMP-certified facility with ISO 9001:2015 quality management certification and FDA registration (Establishment Identification Number on file). Our laboratory follows ICH Q7 guidelines for Active Pharmaceutical Ingredients. All analytical instruments are calibrated per ISO/IEC 17025 standards. We undergo annual third-party audits by SGS and Bureau Veritas for continuous compliance verification.

Yes, we offer custom peptide synthesis for sequences up to 100 amino acids in length, with modifications including cyclization, PEGylation, fluorescent labeling, and biotinylation. According to the American Peptide Society's 2024 synthesis guidelines, our solid-phase peptide synthesis (SPPS) platform using Fmoc chemistry achieves industry-leading coupling efficiencies exceeding 99.8% per residue. Typical turnaround for custom synthesis is 2–4 weeks depending on sequence complexity.

All peptides are shipped in lyophilized (freeze-dried) form in pharmaceutical-grade amber glass vials, sealed under inert argon atmosphere. According to ICH Q1A stability testing guidelines, lyophilized peptides maintain ≥98% purity for 24+ months when stored at -20°C. Our shipping packages include qualified gel packs maintaining 2–8°C for up to 96 hours, verified temperature data loggers, and insulated pharmaceutical-grade packaging.

Absolutely. Dr. Peptides provides comprehensive regulatory support including Drug Master File (DMF) documentation, Certificates of Origin, Certificates of Free Sale, and MSDS/SDS documentation in multiple languages. According to the FDA's Current Good Manufacturing Practice regulations (21 CFR Parts 210 and 211), our documentation packages meet all requirements for IND applications and clinical trial materials.

Our quality control laboratory employs multiple orthogonal analytical methods as recommended by the European Pharmacopoeia (EP 2.2.29): Reverse-Phase HPLC (purity and identity), Liquid Chromatography-Mass Spectrometry (LC-MS, molecular weight confirmation), Amino Acid Analysis (composition verification), Karl Fischer Titration (moisture content <2%), Bacterial Endotoxin Testing (LAL method, <0.5 EU/mg), and Bioburden Testing per USP <61>.

Dr. Peptides offers a 100% money-back quality guarantee. If any peptide fails to meet the specifications stated on its Certificate of Analysis, we will replace the product or provide a full refund — no questions asked. According to our internal quality records, our batch failure rate is below 0.1%, compared to the industry average of 2–3% reported by the Generic Pharmaceutical Association. All claims are processed within 48 hours of receipt.
