Peptide shipping, handling and returns

Dispatch

That is a dispatch commitment, not a delivery promise. Transit time belongs to the carrier and we will not quote a delivery date we do not control.

Cost

Every order ships USPS from Santa Ana. USPS Ground Advantage is free on orders over $150, measured on the subtotal after any volume discount or code. Below the threshold it is a flat $15, whatever your ZIP. Priority Mail and Priority Mail Express are available on any order at the USPS price for your ZIP plus $5, and Priority is never less than $18 where that would undercut Ground. The checkout shows the exact figure for your address before you place the order; the ranges below are for a parcel under one pound, which is nearly every order, at USPS prices effective July 12, 2026.

Tracking, on every order

Every parcel carries a USPS tracking number. It is emailed the day the order leaves, and as USPS scans the parcel you get a further email at each step: on its way, out for delivery, delivered. The number works on usps.com at any time. Order updates go to the email and mobile number given at checkout and to nothing else.

How the material travels, honestly

Peptides ship as sealed lyophilized powder, which is the whole reason the category can ship at all. Dry solid sits in a far slower degradation regime than solution and tolerates several days of ambient transit without drama. The industry habit of implying every vial needs a cold chain sells insulation more than it protects material.

What does matter is what happens when the parcel arrives. A vial that has been in a cold hold and is opened straight into a warm room takes up condensation immediately, and a lyophilized cake is hygroscopic enough to absorb it before anyone notices. Let a sealed vial reach room temperature before breaking the seal. The storage and stability guide covers the chemistry and the arithmetic.

Packaging

Vials ship sealed, cushioned and in opaque outer packaging with no compound names on the exterior. Each parcel carries its packing record listing SKUs, sizes and lot identifiers where those are populated, so the shipment can be reconciled against the order and against the product records without contacting us.

Where we ship from, and where to

Every order leaves one building: 1403 N Tustin Ave, Santa Ana, California, in central Orange County. We ship throughout the United States from that address on the terms above. The cutoff is the same whether the parcel is going to Irvine or to Maine; what changes with distance is the carrier's transit, which its tracking states and we do not.

Southern California is a short ground haul from Santa Ana, and four pages describe delivery to each part of it and name the cities they cover: Orange County, our home county and the one place an order can be collected by arrangement instead of shipped; Los Angeles and Ventura County; the Inland Empire, meaning San Bernardino and Riverside counties out to the Coachella Valley; and San Diego County. None of them describes an office anywhere but Santa Ana, because there is not one. If you arrived here from a search for peptides near me, that page says plainly what we are and are not.

International destinations are not offered at present. Research chemicals cross borders under each country's own import rules and carrier restrictions, and we would rather decline an order than ship one we cannot honestly say will arrive.

Returns — all sales are final

Research chemicals do not come back. Once a vial leaves a controlled chain of custody there is no honest way to restock it, whatever its seal looks like, so we do not accept returns and no returned material ever re-enters inventory. A policy that pretends otherwise is a policy for reselling vials of unknown history, and that is the practice this whole catalog exists in opposition to.
