What Peptide Sciences does

Peptide Sciences was a direct-to-consumer e-commerce supplier of research-grade peptides, proteins, and amino acids intended for scientific research and development use. The company's sole product category was research peptides sold as one-time purchase items through its website at peptidesciences.com, with no subscription, licensing, or recurring revenue model. Its customer base consisted of research laboratories and independent investigators requiring high-purity peptides, and the firm differentiated through documented third-party testing, batch-specific purity verification, and supply-chain transparency.

The business operated with 1-10 employees out of Henderson, United States, and was privately held with no disclosed funding rounds, parent company, or investor base. The sole identified principal is founder Daniel Brzezinski. The company held registered brand-name and trademark rights over the Peptide Sciences name.

In 2024, Peptide Sciences voluntarily ceased operations and discontinued the sale of its research products. Following the shutdown, the company no longer accepts orders or engages in customer acquisition, marketing, or distribution. It retains its intellectual property portfolio and has publicly committed to monitoring and enforcing its trademarks against unauthorized third parties that claim affiliation or represent themselves as successors. The firm is classified as closed, with remaining activity limited to IP enforcement.

Core offering

Peptide Sciences synthesized and sold highly purified peptides, proteins, and amino acids intended exclusively for scientific research and development. Products were sold as finished physical research-grade peptide preparations, with documented batch-specific purity testing and third-party verification, through a direct-to-consumer e-commerce storefront before operations were voluntarily shut down.

Product overview

Peptide Sciences was a single-product research peptide supplier offering peptides exclusively for scientific research and development. The company has voluntarily shut down operations and discontinued the sale of its research products. The product portfolio consisted solely of research peptides as a unified offering, with no modules, sub-products, or platform architecture.

Differentiator

Problem solved

Functional benefit

Products and services

• Research Peptides Highly purified research-grade peptides, proteins, and amino acids synthesized and sold by Peptide Sciences exclusively for scientific research and development use; intended for laboratories and independent investigators and sold as one-time product purchases through the company's e-commerce site before operations were voluntarily shut down.

Quantifiable outcome

• The company shut down operations in 2026, prompting laboratories to seek alternative suppliers

Broad incumbents

• Bachem: Bachem is a leading global manufacturer of peptides and oligonucleotides for pharmaceutical and research applications. It is comparable to Peptide Sciences as a peptide producer serving research and therapeutic customers, but at much larger scale and with broader CMC capabilities.
• Bio-Techne: Bio-Techne is a large life-science tools company offering proteins, peptides, antibodies, and reagents. It serves the same research laboratory customer base as Peptide Sciences but across a much broader reagent and assay portfolio.
• Thermo Fisher Scientific: Thermo Fisher supplies peptides, proteins, and reagents through its life sciences segment and competes for the same research customer wallet. It is a broad incumbent with overlapping product categories but a far larger and more diversified portfolio.

Direct peers

• GenScript: GenScript offers custom peptide synthesis and a broad catalog of research-grade peptides and proteins for life science customers. It directly overlaps with Peptide Sciences in serving laboratories and investigators with synthesized peptides, while operating at significantly greater scale.
• CPC Scientific: CPC Scientific is a peptide CDMO providing custom peptide synthesis at research and GMP scales. It is a direct comparable in core capability (peptide manufacture) and customer base (research labs and biotech developers).
• CSBio: CSBio is a peptide synthesis company offering custom and catalog peptides plus synthesis instrumentation. It directly competes with Peptide Sciences in providing research-grade peptides to scientific customers.
• Vivitide (formerly American Peptide Company): Vivitide manufactures custom peptides and peptide APIs for research and clinical applications. It is a direct peer in custom peptide synthesis serving laboratory and biopharma customers.
• AAPPTec: AAPPTec supplies peptide synthesis reagents, resins, and amino acids along with custom peptide services. It overlaps with Peptide Sciences in providing peptide-related inputs and synthesis services to research customers.
• SynPeptide: SynPeptide is a peptide CDMO focused on custom peptide synthesis for biotech and research customers. It is a direct peer in service offering and target market, though operating primarily as a B2B manufacturer rather than a direct-to-consumer storefront.

Regional players

• Peptide Institute: Peptide Institute is a Japanese manufacturer of high-purity peptides for research and pharmaceutical use. It is comparable in core manufacturing capability and quality positioning but primarily serves the Japanese and Asian markets rather than the U.S. e-commerce channel Peptide Sciences operated.
