HGH 24iu

Recombinant human growth hormone, the full 191-amino-acid somatropin sequence. As the endogenous ligand of the growth hormone receptor it is the reference compound against which every secretagogue in this catalogue is measured.

About HGH 24iu

Somatropin acts directly at the growth hormone receptor, dimerising it and triggering JAK2/STAT5 signalling, which distinguishes it fundamentally from the secretagogues that work upstream by provoking endogenous pituitary release. That difference is the point of most comparative work: secretagogues preserve pulsatility and negative feedback, while direct receptor agonism does not. This 24iu vial, roughly 8mg of protein, is a standard research presentation. Recombinant protein is more fragile than synthetic peptide, so cold-chain handling and avoidance of agitation matter more here than elsewhere in the catalogue.

Storage and reconstitution

Store lyophilized peptide at -20°C in a dry, dark environment. Reconstitute in bacteriostatic water. Once reconstituted, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles. Lyophilized powder is stable at room temperature for shipping and short-term storage.

Shipping within Canada

Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Parcels leave British Columbia, Canada and travel entirely within the country, so nothing on this order crosses a border, clears customs or is held by CBSA. Orders over CA$200 ship free; see the shipping page for transit times by province.
