Genotropin, manufactured by Pfizer, is a licensed pharmaceutical recombinant Human Growth Hormone (somatropin) formulation with full regulatory approval for growth hormone deficiency and related endocrine indications. This single pen presentation delivers the same 36IU prefilled pharmaceutical grade somatropin as CSD’s 5 pen combo pack, providing a standalone procurement option for researchers requiring a single unit for initial compound evaluation, supplementing an existing protocol, or research designs where a single 36IU pen matches the defined experimental supply requirement without committing to the full 5 pen combo volume.
The single pen format serves a distinct procurement purpose from the combo pack. Researchers initiating Genotropin research, comparing Pfizer’s pharmaceutical grade rHGH against research grade alternatives in a limited initial evaluation, or requiring a single supplementary pen to extend an existing protocol without purchasing additional combo packs will find this standalone format the most practical procurement option. The 5 pen combo remains the appropriate choice for extended protocols requiring the full 180IU total supply across matched Pfizer manufacturing batches.
Pfizer’s pharmaceutical manufacturing process for Genotropin involves significantly more rigorous quality control, batch testing, and regulatory oversight than research grade rHGH production. As with the combo pack, authenticity verification is a meaningful consideration in this product category given the prevalence of counterfeit pharmaceutical HGH products in unregulated markets. CSD’s sourcing process verifies genuine Pfizer product before stocking, applying the same authenticity standard to this single pen as the combo presentation. The prefilled pen format eliminates reconstitution requirements and the approximately 3 day post reconstitution stability limitations of lyophilized vial preparations, delivering pharmaceutical grade stability and consistent dosing across the pen’s full usage capacity.
Pfizer Genotropin is stocked by Canada Steroid Depot following the same rigorous third party verification process applied to every product in our range, with additional authenticity verification specific to pharmaceutical branded products given the counterfeit risk in this category. CSD stocks Genotropin in both this single pen format and the 5 pen combo, giving researchers procurement flexibility based on protocol volume requirements from a single verified Canadian supplier. All orders ship discreetly across Canada in plain, unmarked packaging with no identifying information on the exterior.
Store at 2–8°C away from direct light. Do not freeze. Keep upright. Intended for research purposes only.
Commonly researched alongside IGF-1 LR3 and GHRH analogue compounds in comparative growth hormone axis and anabolic signaling studies. Browse CSD’s full HGH and peptide range for complete sourcing.
Arrived as well as can be expected. I would’ve preferred Canada Post as they put it in the mailbox. Purolator took it back to the hub took a while for me to get it. It’s the real McCoy I’ve used it it works well. I feel very good and healed up an old injury in my shoulder.

Pfizer HGH Pen 36 IU is a GENOTROPIN GoQuick pre filled pen containing recombinant human growth hormone (somatropin). Each pen contains 12mg of somatropin, equivalent to 36 IU, in a two chamber cartridge designed to mix the growth hormone powder and sterile solvent within the pen before first use.
Each GENOTROPIN GoQuick 12mg pen contains 36 IU of recombinant somatropin. This single pack presentation provides one pen containing a total of 12mg, equivalent to 36 IU of human growth hormone.
Somatropin is recombinant human growth hormone that binds to growth hormone receptors throughout the body. This activates growth hormone signaling and promotes downstream production and activity of insulin like growth factor 1 (IGF-1), which contributes to normal growth, protein metabolism, tissue development, and other physiological functions regulated by the growth hormone axis.
The GoQuick pen requires an internal mixing step before first use. It contains a two chamber cartridge with lyophilized somatropin powder in one chamber and sterile solvent in the other. The components are mixed by operating the pen mechanism, so no separate bacteriostatic water or external diluent vial is required.
Before mixing, GENOTROPIN GoQuick should be refrigerated at 2–8°C, protected from light, and never frozen. After the powder and solvent have been mixed inside the pen, the product should remain refrigerated at 2–8°C and may be stored for up to 4 weeks while protected from light.
