HCG 5000 IU
$75.00
HCG (Human Chorionic Gonadotropin) 5000 IU is a highly researched peptide hormone commonly studied for its role in hormonal signaling, endocrine support, and reproductive biology. Widely utilized in scientific and clinical research settings, HCG is valued for its ability to mimic luteinizing hormone (LH) activity within the body.
Trusted by researchers worldwide, HCG plays a key role in studies involving testosterone regulation, fertility pathways, and hormonal balance.

HCG is a heterodimeric glycoprotein hormone, not a peptide. Two separately encoded chains are held together without a covalent bond, an alpha chain of 92 residues shared with LH, FSH and TSH, and a beta chain of 145 residues that makes it hCG. Roughly a third of its mass is carbohydrate, and that glycosylation is not decoration.
Supplied as 5000 IU of lyophilised material in a sealed, stoppered vial with 5 mL of bacteriostatic water. Potency is defined by bioassay, which is why the label reads IU rather than milligrams.
HCG 5000 IU is purified, verified, filled and freeze dried in our own lab in Ontario, Canada. It is not imported finished and relabelled.

Why choose HCG
What it is chosen for.
Hormonal signaling support. Commonly studied for its LH-mimicking properties and role in endocrine research.
Testosterone pathway research. Frequently researched for its involvement in stimulating natural testosterone production.
Reproductive health studies. Used extensively in fertility and reproductive biology research models.
Premium quality. Manufactured to high purity standards and rigorously quality tested.
The compound
HCG, in short.
A glycoprotein, not a peptide
Two separate chains held together without a covalent bond, and roughly a third sugar by mass. The sugars are not decoration, they are why it lasts in circulation.
Two chains
An alpha chain of 92 residues, shared with LH, FSH and TSH, and a beta chain of 145 residues that makes it hCG.
Dosed in units
Potency is defined by bioassay, not by weight, which is why the vial says IU and not mg. That standard dates to 1938.
Found in 1927
Aschheim and Zondek demonstrated it in the urine of pregnant women.

The problem with this market
Every vial said 99% pure. None of them were.
Researchers ordered from six online peptide sellers. Half never arrived at all. Here is what was in the three vials that did.
was actually peptide
was actually peptide
was actually peptide
Endotoxin in all three, and no buyer had any way of knowing. Not one of those sellers published a test.
We publish ours. Raw material arrives in Ontario, we purify, verify, fill and freeze dry it here, and the certificate for the batch you receive is in the photos above with the lab and the test date on it.
Three vials is a small sample and the compound was semaglutide, not the one on this page. It is the only peer reviewed teardown of this market that exists, which is itself the point. Ashraf et al., Journal of Medical Internet Research, 2024, DOI 10.2196/65440.
Why buy it here
Same molecule. Different supply chain.
We make it. We do not resell it.
Raw material in, finished vial out, same facility. Most of this market buys vials already filled and puts a label on them.
The certificate is for the batch in the box.
Not an undated PDF from some other run. Replaced here every time a new batch is released, with the lab and the date on it.
Minus 20 °C until it is packed.
Our own freezer to the moment it ships, then tracked with Canada Post. No customs queue, no week at ambient in transit.
Every row is a fact about how the product is made and handled, and every row is one we can evidence.
Before you order
The practical questions.
When will my order ship, and how does it arrive?
Orders placed before 2pm ET are dispatched within 2 business days. Everything goes tracked with Canada Post. Shipping is free on orders over $200.
What exactly is in the box?
A sealed, stoppered and capped vial containing the fill weight shown on this page, plus a vial of bacteriostatic water sized to the product. Nothing else is required.
How is it stored before it ships?
Every vial is held at −20 °C in our own lab freezer until the moment it is packed.
Where is this made, and who tests it?
Raw material arrives in Ontario and is purified, verified, filled and freeze dried in our own facility. Every batch is tested before it is released.
Can I see the certificate for the batch I will receive?
It is already on this page, in the product photos. Nothing ships until its certificate is back from the lab, and we swap the photo the moment the batch changes, so what you are looking at is what is in the box.
What is your return policy?
Once a vial leaves our freezer we cannot
take it back. A vial stored somewhere we cannot
see is one we can no longer vouch for, and we will not put it back into circulation
for someone else. So all sales are final.
The exception is anything that is our fault. If what arrives is damaged, defective
or not what you ordered, send us a photo and we will replace it or refund it. Get in
touch soon after delivery so we can act on it while it is still clear what happened.
What we cannot cover is how the product is handled, stored or used once the box
reaches you, for exactly the same reason we cannot take it back.
