Made in the USA · Quality Assurance

US-Manufactured Peptides, Sourced with API from Green List Manufacturers Only

Every Wholesale Peptide Distributors peptide is synthesized in the United States in ISO 5, cGMP-aligned cleanroom facilities — using raw API sourced exclusively from FDA green list manufacturers. HPLC ≥99% purity, endotoxin testing per lot, and full chain-of-custody documentation — built for the compliance demands of compounding pharmacies and licensed medical facilities.

US Manufacturing & Green List Sourcing

Made in the United States — Every Batch

All Wholesale Peptide Distributors peptide API is manufactured in the United States in ISO 5, cGMP-aligned cleanroom facilities. Unlike suppliers who import finished product from overseas, our peptides are synthesized domestically in controlled cleanroom environments — giving compounding pharmacies and licensed clinics a fully traceable, US-origin supply chain with no gaps in chain-of-custody documentation from raw material to final lot.

The raw API used in our manufacturing process is sourced exclusively from FDA green list manufacturers — API suppliers that appear on FDA's import alert green list, confirming they are not subject to import restrictions and have demonstrated compliance with applicable quality standards. This means every lot you receive starts from verified, FDA-recognized raw material, not unqualified overseas material.

For our 503A compounding pharmacy customers, we can provide full manufacturer documentation: facility certifications, green list status verification, validation summaries, and quality system overviews — all available in your account portal as part of your QA file package.

Testing Protocols

HPLC Testing & Quality Protocols — Every Lot

Every lot of Wholesale Peptide Distributors wholesale peptide API is tested against a comprehensive panel. No product ships without a complete CoA on file.

HPLC Purity Testing (≥99%)

High-Performance Liquid Chromatography (HPLC) is the gold standard for peptide purity verification. Every lot of Wholesale Peptide Distributors peptide API is tested by HPLC to confirm ≥99% purity. The HPLC chromatogram and purity calculation are included in the CoA delivered with every wholesale order.

What it shows: Total peptide purity, identification of impurities, confirmation that related substances are below specification limits. For compounding pharmacies, HPLC data is essential for USP-compliant quality review.

Mass Spectrometry Identity Confirmation

Identity testing via mass spectrometry confirms that the peptide is the correct compound — not just that it is pure. Each lot CoA includes mass spectrometry data showing the molecular mass of the peptide consistent with theoretical molecular weight.

Why it matters: HPLC purity alone does not confirm identity. Mass spectrometry prevents incorrect compound delivery and is required by many pharmacy QA programs for API acceptance testing.

Endotoxin Testing (LAL Method)

Endotoxin (pyrogen) testing is critical for any peptide intended for injectable compounding. Wholesale Peptide Distributors tests every lot using the Limulus Amebocyte Lysate (LAL) method, with results reported in EU/mg and compared against specification limits appropriate for injectable use.

Specification: Endotoxin <10 EU/mg as standard specification for injectable-grade peptide API. Tighter specifications available for select compounds per pharmacy request.

Sterility & Residual Solvent Testing

For select finished-dose products and high-specification bulk API lots, sterility testing and residual solvent testing (per USP <467>) are available upon request or included as standard for qualifying product categories.

Residual solvent results confirm that manufacturing solvents are below ICH Q3C limits appropriate for pharmaceutical use. Sterility testing available for injectable finished-dose products in our catalog.

Documentation

Chain-of-Custody & CoA Documentation Overview

Every Wholesale Peptide Distributors wholesale order ships with a complete documentation package supporting your facility's quality assurance and regulatory compliance requirements.

Certificate of Analysis (CoA)

Lot-specific CoA includes HPLC purity report (≥99%), mass spectrometry identity data, endotoxin results (EU/mg), sterility data where applicable, lot number, manufactured date, and expiration date. Available per lot in your account portal.

Chain-of-Custody Documentation

Every lot is accompanied by chain-of-custody documentation tracing the API from manufacturing through cold-chain delivery. Includes lot traceability, cold-chain temperature logs, and shipping documentation to support your pharmacy receiving records.

Manufacturer Quality Documents

Facility certifications, quality system summaries, and cGMP compliance documentation available from our manufacturing partners on request. Standard for 503A pharmacy QA files. Contact your account manager to request manufacturer documentation packages.
