FAQ
1: What are injectable peptides and what are their core compositional features?
A: Injectable peptides are high-purity synthetic amino acid fragments designed for parenteral administration. Our products meet strict injectable-grade standards with rigorous control over purity, moisture content, residual solvents, bacterial endotoxins and particulate impurities, without irritative contaminants that may trigger adverse reactions after injection.
2: What types of injectable peptides do you supply mainly?
A: We provide mainstream research-grade injectable peptides including BPC-157, TB-500, CJC-1295, Ipamorelin, Semaglutide, Tirzepatide, MOTS-c and more. Custom specifications and adjustable net content per vial are available upon request.
3: What is the correct reconstitution method for injectable peptides before use?
A: Use sterile bacteriostatic water for injection to slowly add solvent along the inner wall of the vial to reconstitute lyophilized peptide powder, avoiding direct impact on powder which may cause peptide denaturation. Gently swirl the vial for complete dissolution instead of vigorous shaking.
4: What are applicable injection sites and common administration methods for these peptides?
A: Subcutaneous injection is the most common administration route, with typical injection sites including abdominal area, thigh and upper arm fatty tissue. Intramuscular injection is acceptable for certain individual peptides. Intravenous injection is not recommended without professional medical supervision.
5: Are your injectable peptides safe for injection? What test documents can you provide to prove safety?
A: Each batch is tested strictly via HPLC purity analysis, endotoxin testing, microbial limit test and heavy metal inspection. We can provide batch-specific COA (Certificate of Analysis) to verify all indicators comply with injectable-grade impurity limits.
6: Are there any contraindicated groups for injectable peptides? What potential side effects should be noticed?
A: They are not suitable for minors, pregnant women, patients with severe liver and kidney dysfunction, autoimmune disorders or coagulation disorders. Mild redness, slight swelling or itching at the injection site may occur occasionally, which generally relieve spontaneously within a short period.
7: What are the respective storage requirements for unopened injectable peptides and reconstituted peptide solution?
A: Sealed unopened lyophilized peptide vials must be stored refrigerated at 2℃–8℃ away from light. After reconstitution, the peptide solution needs refrigeration and should be consumed within 2–4 weeks; freezing is forbidden to prevent structural degradation and activity loss.
8: What packaging solution do you use to keep injectable peptides stable during transportation?
A: Finished peptides are vacuum-sealed in sterile crimp-top vials. Temperature-sensitive peptides are packed with insulated foam boxes and ice packs for temperature control, plus light-proof outer aluminum packaging to prevent oxidation and activity degradation.
9: What international shipping options do you offer for small samples and bulk orders of injectable peptides?
A: Small trial samples can be delivered door-to-door via DHL, FedEx or UPS international express. Large bulk shipments can be arranged by air freight or sea freight. We supply complete shipping documents and offer assistance for customs clearance procedures.
10: Do you support customization services for injectable peptides? What is your minimum order quantity (MOQ)?
A: We support customized filling dosage per vial, private label labeling, customized packaging and bulk raw peptide customization. MOQ varies by peptide item. Both small trial orders and mass production orders are negotiable. You can contact our sales team for detailed quotations.
