Research-Grade Compound

HGH is the abbreviation researchers use for human growth hormone, the pituitary polypeptide hormone that signals through the growth hormone receptor and induces hepatic IGF-I gene expression. Alanine-scanning mutagenesis reported in Science in 1989 mapped the receptor-binding epitope on the hormone residue by residue, and a 2010 pharmacology reference volume summarises the wider growth hormone axis.

Purity standard: HGH is sourced to ≥99% by HPLC — sourcing spec.

Buying HGH — Frequently Asked Questions

Is HGH from Peptide.Express tested for purity?

Every lot is sourced against a >=99% by HPLC standard and ships with a batch-specific Certificate of Analysis that includes the HPLC chromatogram. That standard is a sourcing specification, not a claim about any particular vial's measured value; the figure on the CoA for your lot is the measurement.

How should HGH research material be stored?

Store the lyophilized vial at -20 C, desiccated and protected from light. After reconstitution, keep the solution at 2 to 8 C in single-use aliquots. Reconstituted stability has not been established for this material, so do not assume a shelf life.

Is HGH approved by the FDA?

Recombinant human growth hormone is regulated as a prescription biologic in the United States for defined endocrine indications. The research material listed here carries no FDA approval of any kind, is not a drug, and is sold strictly for in-vitro laboratory investigation.
