Buying Guide — 2026-10-07
HCG is a delicate glycoprotein, so where you buy a 5000IU vial matters as much for the handling as for the purity. A good research source proves what is in the vial with documentation and ships it in a way that preserves stability. Here is what to check before ordering, and how Platinum Biolabs compares.

For a broader checklist, see where to buy research peptides.
Unlike many peptides, reconstituted HCG is used within about 30 days and must stay refrigerated. Buying the lyophilized (dry) vial from a US source — rather than a pre-mixed solution shipped slowly from overseas — means the material arrives stable and you control the reconstitution window.
