FAQ’s

Peptides are formed by joining amino acids through peptide bonds — a chemical link created when one amino acid’s amino group reacts with another’s carboxyl group, releasing water. In laboratories, scientists typically use a method called solid-phase peptide synthesis (SPPS): Initiation: The first amino acid is bound to a solid resin, keeping its amino group protected. Elongation: The protective group is removed, and the next amino acid is added to form a new bond. Repetition: These steps repeat until the full peptide chain is complete. Completion: The peptide is detached from the resin, and all remaining protective groups are removed. This process enables the creation of peptides with precise amino acid sequences for research and development purposes.
Yes, trace amounts of mannitol are included in all our peptides. Mannitol, a sugar alcohol, plays several key roles: Stability: Prevents aggregation and helps maintain peptide structure. Solubility: Improves how easily peptides dissolve in water or saline. Moisture Control: Absorbs humidity to protect against degradation. Handling: Enhances powder flow for easier measurement and transfer. Mannitol also ensures the peptide powder remains visibly present in the vial.
Because peptides attract moisture, allow them to reach room temperature before opening. Follow these best practices: Weigh Quickly: Work in a clean area and measure only what’s needed. Seal Securely: Close the vial tightly after use. Store Properly: Keep unused peptides at –20°C or below, in sealed containers with a desiccant. Proper storage minimizes oxidation and bacterial degradation, extending shelf life. When dissolving, use sterile water or buffers suited to the peptide’s characteristics, and apply sonication if necessary. ⚠️ Note: Peptides in liquid form are less stable than lyophilized powders. If stored in solution, keep at –20°C in sterile buffers at pH 5–6.

No — we do not supply pre-blended formulations (e.g., Ipamorelin with CJC-1295 MOD GRF). Such blends often have inconsistent ratios that make precise dosing difficult. For accurate research results, we recommend purchasing peptides separately. You can combine them as needed — for example, mixing 100 mcg of Peptide A and 100 mcg of Peptide B in the same syringe allows for correct microgram control. Purchasing peptides individually also ensures consistency and cost-effectiveness.
Yes. Every product includes a downloadable Certificate of Analysis (CoA). Visit the product page and click “Certificate of Analysis” to obtain the PDF. All CoA documents are official records for informational use only and must not be edited or altered.
Typical impurities found in purified peptides include deletions and truncations in the amino acid sequence, often caused by steric hindrance or structural folding during synthesis: Truncation: The peptide is shorter than intended. Deletion: One or more amino acids are missing from the sequence. Reagents used to detach the peptide from the solid phase can also leave trace residues, but these are normally volatile and removed during purification and freeze-drying.
Peptide Purity: Measured using HPLC (High-Performance Liquid Chromatography) and Mass Spectrometry. Purity reflects the proportion of the peptide relative to other components detected — excluding water and salts. Peptide Yield: Determined via Amino Acid Analysis (AAA) to calculate the actual peptide amount. Differences between weighed and measured amounts often reflect residual salts or moisture.
Lipopolysaccharides (LCPS), also known as endotoxins, are molecules found in the outer membrane of Gram-negative bacteria (e.g., E. coli). They can cause strong immune reactions, making their absence essential in high-purity peptide products. We eliminate this risk by producing synthetic peptides, not biologically expressed ones. This chemical synthesis process ensures: No bacterial contamination Consistent purity and composition Reliable research performance Our advanced synthetic techniques allow peptides to be built precisely and safely — completely free of LCPS and other bacterial by-products. In short, our strict synthetic production process guarantees clean, consistent, and contamination-free peptides for reliable research and therapeutic use.
