Who tests these peptides?
Every lot is analysed by an independent third-party laboratory — MZ Biolabs or Chromate. Each certificate covers identity confirmation by mass spectrometry, HPLC purity, date of analysis and an endotoxin result. Our floor is 98% purity; anything below it does not get listed.
How long does delivery take?
Orders placed before 2 PM Pacific ship the same business day. Free shipping arrives in 3–5 business days; overnight is available at checkout. Tracking is emailed automatically.
How should I store the vials?
Vials ship lyophilised, which is stable at ambient temperature in transit. Keep sealed vials cool, dry and dark; for storage past three months use −20 °C. Once reconstituted, refrigerate at 2–8 °C and use within 30 days.
Do you offer volume pricing?
Yes — three vials of the same item take 10% off, five or more take 18%. The discount applies automatically in the cart. For larger research quantities email support@pureforgelabs.com and we will quote per gram.
What is the shelf life of an unopened vial?
Each label and certificate lists a best-by date. Stored as directed, lyophilised peptides are typically stable 12–24 months, and longer at −20 °C. Actual stability depends on sequence and handling.
