Why does my peptide vial appear to be empty?
At first inspection, vials containing 5 mg, 10 mg, or 20 mg of raw, high-purity, non-lyophilized peptides may appear empty. This is normal and does not indicate a missing product. When peptides are supplied without fillers or excipients, the total mass is extremely small and may only be visible as a faint film or light residue on the interior surface of the vial. Non-lyophilized products, in particular, can appear as a light dusting rather than a visible solid.
Why is it difficult to withdraw product from the vial?
Lyophilized products are vacuum-sealed to preserve stability and quality. To equalize pressure and access the contents, it may be necessary to inject at least two full 1 mL syringes of air into the vial. Vacuum strength can vary between vials; some seals may feel more pronounced than others. This variation is normal and does not affect product integrity.
What is the purity of Standard Lyophilized products?
Standard Lyophilized products are verified to have a purity of ≥98.5%.
What testing is performed on Standard Lyophilized products?
These products undergo third-party analytical testing to confirm peptide identity and concentration. Testing is limited to purity and composition verification and does not include sterility or endotoxin analysis.
What should I do if I have not received a tracking number?
On business days, shipping labels are typically generated within 24 hours of payment confirmation, after which a tracking number is sent via email. Orders placed after 3:00 PM on Friday are processed the following week, as shipments are not dispatched on Saturdays or Sundays. Tracking information is generally provided at the beginning of the next business week, depending on processing volume.
