We offer HGH for sale as Spectros 72 IU/pen, 1.3ml pen. Spectros 72 IU is Spectrum Pharma's somatropin pen at the higher fill: 72 IU, described as 24 mg of growth hormone, in a 1.3 mL dual-chamber cartridge. The quantity is what tells you which fill you are holding, and both numbers belong together when you check it.
The hormone in the cartridge
Somatropin is recombinant human growth hormone, a 191-residue protein that binds GH receptors and triggers JAK-STAT signalling. Its effects fall into two rough groups. Growth and repair run largely through IGF-1 produced in the liver; metabolism is influenced directly, with increased protein synthesis, mobilised fatty acids and altered glucose utilisation. A higher fill does not add a new mechanism, it only changes how much of the same hormone the pen contains. IU measures biological activity against a reference standard while mg measures the weight of the protein, and because the relationship is fixed for somatropin, the 72 IU label corresponds to 24 mg in the manufacturer's description. The 1.3 mL figure describes the cartridge, not the amount of hormone, and that fixed relationship is why the 72 IU label and the 24 mg description always travel together on this product.
Handling a higher-strength pen
Keep it refrigerated at 2–8°C, never frozen, and leave the cartridge unopened until activation. A fill of 72 IU puts more hormone in a 1.3 mL cartridge than a lower-strength pen of the same size would, so the shelf life after activation matters more: record the date the pen is opened and follow the labelled window rather than an estimate.
Ask the team to confirm which strength is in stock before you commit.
