Shipping Information

Last updated: July 2026

This page explains how AminoStock processes, packs, and ships research orders within the United States. Our goal is simple: get material to your lab quickly, in the condition it left ours, with tracking you can follow the whole way.

Processing time

Orders placed before our daily cutoff of 3:00 PM ET on a business day are prepared and dispatched the same day. Orders placed after the cutoff, on weekends, or on US holidays are processed the next business day. You'll receive a confirmation email when your order is received and a second email with tracking once it ships.

Shipping methods & cost

  • Standard — USPS Priority, 2–3 business days. $4.99 flat, free on orders over $150.
  • 2-Day — UPS 2nd Day Air, 2 business days. $11.99 flat, free on orders over $175 — carts over $175 are automatically upgraded to free 2-day delivery.
  • Overnight — next-business-day delivery when you order before the daily cutoff. $39.99 flat.

Pick your speed at checkout; delivery estimates are shown with each option.

Cold-chain & handling

Lyophilized (freeze-dried) peptides are stable at ambient temperature for the length of normal transit, so standard packaging preserves them without added cost. Where a compound benefits from cooler handling, we include insulated packaging and a cold pack. All shipments use discreet, plain outer packaging with no description of the contents on the exterior.

Tracking your order

A tracking number is emailed as soon as your order leaves our facility. You can also look up status at any time from your account using the email address on the order — no password required.

Where we ship

At this time AminoStock ships to destinations within the United States only. We do not ship internationally. Orders to addresses outside our serviceable area will be canceled and refunded.

Shipment protection

Every order is covered by shipment protection. If a package is lost, stolen, or arrives damaged, contact support and we'll arrange a free replacement or a full refund. See our returns page for how to start a claim and the time window that applies.
