Shipping & Delivery
Why did my peptides arrive warm?
Lyophilized peptides are heat-stable. Short exposure to elevated temperatures does not degrade peptide structure.
Degradation is driven by moisture, which is removed during lyophilization.
How long does shipping take?
Domestic orders arrive within 2–4 business days. International orders typically take 5–10 business days.
Purity & Testing
What is the difference between Peptide Purity and Peptide Content?
Purity measures correct peptide sequence percentage.
Content accounts for salts, counterions, and residual moisture.
How do I interpret the COA?
Review HPLC for purity and MS for molecular weight identity.
Technical & Stability
Can I refreeze a peptide after reconstitution?
No. Refreezing causes ice-crystal damage to peptide structure.
Which solvent should I use?
Bacteriostatic Water is preferred for multi-use research. Sterile Water is for single-use only.
Orders & Legal
Do you offer medical advice?
No. All compounds are strictly for laboratory research use only.
What is your return policy?
Returns are not accepted once products leave custody, except in verified shipping damage cases.
