HCG: Research Summary and How to Judge a Supplier
Human chorionic gonadotropin, a heavily studied glycoprotein hormone supplied for laboratory research. This profile sets out what is actually published, what a 5000IU vial should cost, and the specific documentation to ask for before ordering HCG from any research supplier.

What HCG is
HCG is a glycoprotein hormone with an extensive clinical literature in fertility medicine and endocrine testing. It acts on the LH receptor, and its pharmacokinetics, assay behaviour and stability are all documented in detail.
On the research market it is sold in international units, typically 5000IU or 10000IU per vial, and it is one of the few products here where under-filling is easy to detect with a standard pregnancy test strip after reconstitution.
What the evidence base looks like
The published record here is deep enough that the pharmacology itself is not in dispute; the open questions are about supply quality rather than mechanism.
Our library records roughly 340 relevant publications for HCG and grades the evidence as strong. That grade describes the weight of research, not a judgement about safety or effect, and it is reviewed as new work is published.
Supplier quality: what to check on HCG
Potency loss from poor cold-chain handling is the main failure mode, and it is invisible without assay data on the delivered batch.
The practical checklist is the same on every product but weighted differently here: a batch-matched certificate of analysis, an identity method appropriate to this molecule rather than purity alone, clear peptide content per 5000IU vial, and a supplier that will answer a technical question before taking payment.
Typical UK pricing
The lowest price we currently track for a 5000IU vial is £29.95, against a market median nearer £43. Compare on price per milligram rather than per vial, because vial sizes across suppliers are rarely identical.
A listing well below the tracked low is worth investigating rather than celebrating. On this compound the cost of doing it properly is largely analytical, and that is the first thing an unusually cheap supplier stops paying for.
Frequently asked
Is HCG approved for human use?
No. Everything listed here is supplied for laboratory research use only, and nothing on this page is medical advice.
How much should HCG cost?
Tracked UK prices start around £29.95 for a 5000IU vial, with the market median closer to £43.
What is the single most useful check on HCG?
Potency loss from poor cold-chain handling is the main failure mode, and it is invisible without assay data on the delivered batch.
