FAQ
Standard tracked shipping is a flat $5.99 per order on orders under $200, no matter how many vials you buy. It covers protective laboratory packing, discreet outer packaging, carrier handling, and a fully tracked domestic service. Orders of $200 or more ship free.
In-stock compounds are verified against lot records before dispatch. Orders are processed and shipped within 10–12 business days.
Orders are processed and shipped within 10–12 business days, covering lot verification and dispatch. Tracking information is provided by email after the order has shipped, and carrier transit time is added on top of that window.
Inventory is lot based and can sell out between browsing and verification. If your lot is unavailable we hold the order, contact you, and offer an equivalent lot, a substitution, or a refund of that line. Backordered items release against the next incoming lot, typically adding 5–7 business days.
Place an order with a merchandise total of $200 or more after volume discounts and before tax. The cart removes the $5.99 shipping charge automatically once you reach the threshold.
A tracking number is emailed automatically once your order leaves our facility. Enter it on the carrier's website to follow every scan from dispatch through delivery.

Freeze drying removes the water that most degradation chemistry depends on. In a sealed, desiccated vial the peptide sits as an amorphous solid with very little mobile moisture available to drive hydrolysis of the backbone or deamidation at susceptible asparagine and glutamine residues, which is why a correctly lyophilized powder tolerates ambient transit for a period measured in weeks rather than hours. A vial that arrives warm has not been compromised; a vial that arrives with a compromised seal has, regardless of its temperature.
That is the reason shipments here travel in rigid protective packaging rather than on ice. A cold chain adds cost, adds failure modes — a thawed pack midway through transit is worse than no pack at all — and buys nothing measurable for a dry powder over a domestic shipping window of this length. What does matter is mechanical protection, since cracked glass and disturbed crimp seals are the realistic transit risks for a small glass vial.
The handling that follows delivery carries far more weight than the transit itself. Record the arrival date, inspect the seal and crimp before anything else, and move vials into their long-term storage promptly — desiccated, dark, and at the temperature the compound's monograph specifies. Reconstituted solution is a different material with a much shorter horizon, so aliquot to single-use volumes rather than repeatedly thawing one stock.
