Peptides are short chains of amino acids that act as tiny instructions for cells. In research, peptides are used to probe pathways, mimic protein regions, or serve as building blocks for assays and method development.
Peptide capsules are research-use formulations designed for controlled storage and handling in laboratory settings. They contain measured peptide material intended for in-vitro research only and are not for human or veterinary use. When available, documentation such as batch testing and COA information supports identity and purity verification.
Certified-Pep supplies research peptides and bioregulators with an emphasis on consistency and verification. Products are synthesized using established peptide manufacturing methods and supported by third-party testing. Batch documentation (including Certificates of Analysis when provided) helps confirm purity and identity for research workflows.
Most orders ship the next business day after processing. Typical delivery time is 2–4 business days once shipped (U.S. domestic), depending on carrier volume and destination. Tracking details are provided once your order leaves the facility.
Peptides are commonly produced using solid-phase peptide synthesis (SPPS), a standard method used in peptide manufacturing. This approach supports consistent sequence assembly and purification to reach high purity suitable for research applications. Where applicable, third-party testing and COA documentation help verify final batch quality.
