Return Policy & Money-Back Guarantee

All sales are final

Because our products are sealed research materials, we can't accept returns or exchanges once an order has shipped, and we don't issue refunds for returned items.

Money-back guarantee

Every peptide vial we sell is guaranteed sterile, endotoxin-free and within ±10% of the labeled fill. If an independent test from Janoshik or Vanguard Laboratory on a sealed vial from your order shows that it fails any of these, contact us with the report and we'll refund the price of that product.

Damaged or lost orders

If your order arrives damaged or is lost in transit, contact us with your order number (and photos for damage) and we'll reship it.
