Buying Guide — 2026-10-13
HCG (human chorionic gonadotropin) is one of the most-purchased research compounds, which also makes it one of the most frequently underdosed and mislabeled. Buying it online safely comes down to a few verifiable checks. Here is what separates a legitimate research vial from a risky one.
Researcher special: code PLATINUM25 unlocks 25% off HCG 5000IU and 10000IU at checkout. Every vial ships with a batch-matched COA.
The single most important check: does the vial come with a Certificate of Analysis that matches the batch you received — not a generic PDF reused across every order? A real COA shows identity confirmation and purity for *that lot*. If a seller cannot produce one, walk away. See what a peptide COA is.
HCG is dosed in international units (IU), and the two common research sizes are 5000IU and 10000IU. Underdosing is the most common quality problem — a vial labeled 5000IU that assays low throws off every calculation downstream. A legitimate COA documents the actual content so your reconstitution math holds.
Look for documented HPLC purity and evidence of cold-chain handling. HCG is sensitive to heat and light, so US-based storage and shipping matter for potency on arrival.
Buying safely also means buying the right amount. HCG is typically administered 2–3× weekly, not daily — so map your weekly IU before ordering. If unsure between sizes, see HCG 5000IU vs 10000IU and how long a 5000IU vial lasts.
For verified research HCG with a batch-matched COA on every vial, see where to buy HCG 5000IU and the broader guide on where to buy research peptides.
Buy HCG safely by verifying a batch-matched COA, confirming IU accuracy and HPLC purity, checking cold-chain handling, and sizing the vial to your weekly protocol. Those five checks eliminate the vast majority of underdosed and mislabeled product.
Code PLATINUM25 takes 25% off at checkout. Every HCG 5000IU and 10000IU vial ships with a batch-matched COA.
