Refund & Returns Policy

At Purpose Labs, we’re in the business of making sure our customers are taken care of. We stand behind the quality of every product we ship — every batch is independently verified to ≥99% purity with batch-specific COAs available for review before you order.

Due to the nature of research-grade peptides and strict regulatory requirements around chemical compounds, we maintain an all-sales-final policy. However, if something goes wrong on our end — a damaged shipment, an incorrect order, a quality issue — we will always make it right. No questions asked.

Due to the nature of research chemical compounds, all sales are final. We do not accept returns or exchanges on opened or used products under any circumstances. This policy exists to maintain the integrity of our quality control process and to comply with applicable regulations around research chemicals.

We encourage all customers to review the batch-specific Certificate of Analysis on our Quality & COAs page before placing an order to confirm our products meet your research specifications.

We will issue a full replacement or refund in the following situations:

The following situations are outside our refund policy:

• Products that have been opened and used without a reported issue at delivery
• Change of mind, accidental orders, or ordering the wrong product
• Delays caused by carriers, customs, or circumstances outside our control
• Products stored improperly after delivery (peptides require −20°C storage)
• International orders seized or delayed by customs
• Requests submitted more than 48 hours after confirmed delivery

If you’re unsure whether your situation is covered, please reach out — we’d rather talk through it than have an unhappy customer.

If you have an issue with your order, here’s how to get it resolved quickly:

If your order arrives damaged, please do the following immediately:

• Do not discard any packaging or damaged products
• Photograph the outer packaging, inner packaging, and damaged product
• Email us within 48 hours with photos and your order number
• We will ship a replacement at no charge within 48 hours of confirmation

We take packaging seriously — every order is packed to maintain cold chain integrity during transit. In the rare event of damage, we’ll make it right immediately.

If your tracking shows delivered but you haven’t received your package, or if your order has been in transit significantly longer than expected:

• Check with neighbors and building management first
• Wait 24 hours after the marked delivery date — carriers sometimes mark early
• Contact us at info@purposelabs.shop with your order number
• We’ll open a carrier investigation on your behalf
• If confirmed lost, we’ll ship a replacement or issue a full refund
