Human chorionic gonadotropin, a heterodimeric glycoprotein built from two non-covalently associated subunits: an alpha subunit of 92 residues, shared with the other glycoprotein hormones, and a beta subunit of 145 residues that is distinctive to this hormone. Both subunits are extensively glycosylated, and the carbohydrate accounts for a substantial share of the intact molecule.
Because the glycosylation pattern varies between preparations and carries much of the biological activity, this material is supplied and quantified in international units of activity rather than by mass. That is why the vial is labelled 10,000 IU and not in milligrams, and it is the reason no single molecular weight or empirical formula is stated below: for a glycoprotein those figures describe a particular preparation rather than the substance. The certificate of analysis for the lot governs.
Supplied as a lyophilized powder.

Lyophilized powder. The sealed vial is stable at room temperature during transit and can be held in a cool, dry, dark place for short periods. For anything beyond short-term holding, store it refrigerated at 36 to 46°F (2 to 8°C), or frozen at minus 4°F (minus 20°C) or below for long-term storage. Keep it away from light, moisture and heat. Lyophilized material is stable for the period stated on the certificate for the lot.
After reconstitution. Refrigerate at 36 to 46°F (2 to 8°C) and use within the window appropriate to the receiving laboratory's protocol. Do not leave reconstituted material at room temperature, and avoid repeated freeze and thaw cycles, which degrade peptide material. Handling and any further storage conditions are the responsibility of the receiving laboratory.
Ships within 24 hours. Ships from Lafayette, Louisiana, by FedEx 2-Day, with a transit time of 2 business days. Orders ship within the United States only.
FedEx 2-Day is $12.50 ($21.00 for orders of 7 or more vials), and free on subtotals of $200 or more after discounts. Overnight is available by quote at checkout.

How Subscribe & Save works
Set a repeat schedule on anything in the catalog and we handle the reorders, every 2, 4, 6 or 8 weeks. Your opening order is billed at the regular price; from the second shipment on, you pay 10% less, shipping is on us, and that rate holds for as long as you stay enrolled.
Pick Subscribe & Save on a product and choose how often it should arrive. The order you place today goes through at the normal price.
When a shipment comes due, your order is created at the reduced rate and a payment link lands in your inbox. Settle it with Venmo, Cash App, Zelle or PayPal; we never charge you on our own.
Your account page lets you push a shipment back, adjust the interval, pause, or end the plan whenever you like. No contract, no exit fee.
What you pay
The rules
The opening order is billed normally. The reduced rate rewards researchers who keep their plan running.
A pay link arrives by email whenever a shipment is ready. No card is kept on file and nothing is charged for you.
Delay one delivery, switch to a longer or shorter interval, or put the whole plan on hold from your account.
Once a plan is cancelled, no new orders are created. There is no commitment period and no cancellation charge.
Every reorder on your schedule ships at no cost to you, whatever its size.
A promo code can be used on your opening order. Later deliveries use the Subscribe & Save rate instead.
