Generic Peptides HCG 5000 IU and 10000 IU Research Vials

Generic Peptides HCG supplies human chorionic gonadotropin in 5000 IU and 10000 IU lyophilised vials. The hormone is a glycoprotein built from an alpha chain of 92 and a beta chain of 145 amino acids, and it works as an agonist of the LH/CG receptor, which places it in the group of gonadotropins studied for gonadal stimulation. The molecule is standardised biologically rather than by weight, so both options are labelled in international units, and HCG for sale here comes from a GMP manufacturer with a Certificate of Analysis on file.

• Human chorionic gonadotropin (hCG) - 5000 IU or 10000 IU per vial
• Glycoprotein hormone, LH/CG receptor agonist acting on Leydig cells
• Biphasic profile: initial phase 6 to 11 hours, terminal 23 to 37 hours
• GMP-manufactured, HPLC-verified, COA on file per batch

Variant Comparison

Both vials hold the same hormone and differ in how many international units the batch contains.

Solvent decides the arithmetic: a 5000 IU vial with 1 ml gives 5000 IU per ml, so 0.1 ml on a U-100 syringe holds 500 IU, while the same vial with 2 ml gives 2500 IU per ml and 0.1 ml holds 250 IU.

How HCG Works

hCG binds the same receptor as luteinising hormone and signals the Leydig cells of the testis, which is why it is used clinically when endogenous gonadotropin signalling has to be stimulated. Its profile is biphasic: an initial phase of 6 to 11 hours followed by a terminal phase of 23 to 37 hours, with about 31 hours measured after intramuscular dosing. That long tail is the reason a single injection keeps the receptor occupied for days rather than hours.

Reconstitution and PCT Context

Add bacteriostatic water slowly down the vial wall and do not shake the solution, because glycoprotein hormones are damaged by foaming. Store the powder cold and the reconstituted vial at 2-8 C. In cycle planning the hormone appears in PCT discussions, where it is read next to a selective oestrogen receptor modulator such as Clomid or Nolvadex, and the older HCG listing covers the same substance from another brand line.

Quality & Authenticity

Every batch is produced under GMP conditions and checked by independent HPLC, with the Certificate of Analysis held for the batch. Approved labels list contraindications that include precocious puberty and androgen-dependent tumours. hCG is detectable in urine by immunoassay for 7 to 10 days after administration according to WADA, which matters in a tested sporting setting rather than in the laboratory.

Consult a healthcare professional before any cycle. Where a stack suppresses natural testosterone, PCT is required. Doses are common community protocols.
