Product overview
HGH 191AA 15iu/10vials is a sterile lyophilized preparation of recombinant human growth hormone (somatropin), synthesized as the full 191-amino-acid sequence in an E. coli expression system. Each vial contains 15 international units (approximately 5mg by mass at the standard 3.0 IU/mg conversion) — a higher-strength format for protocols that draw larger working volumes per administration.
Independently assayed by HPLC and MS, and lot-traceable to the source preparation. Intended for preclinical research on the growth-hormone axis and downstream IGF-1 signaling.
Typical research dose range
Preclinical and clinical GH-axis literature uses recombinant human GH across a wide range depending on endpoint. The 15iu-per-vial format suits research-protocol exposures in the 3-10 IU per administration range in animal models, with timing keyed to natural pulsatile patterns. Researchers should consult source literature for the specific endpoint under investigation.
Stack and pairing
Recombinant HGH is frequently studied alongside GHRH analogs (CJC-1295, tesamorelin) and ghrelin-mimetic secretagogues (ipamorelin) in protocols examining receptor-saturation kinetics and pulse-pattern interactions across the GH axis.
Reconstitution and storage
Reconstitute each vial with 1-3 mL of bacteriostatic water for the target working concentration. Use sterile technique, and inject the bacteriostatic water against the side of the vial rather than directly onto the cake to avoid mechanical denaturation. Once reconstituted, store at 2-8 °C and use within 30 days for best stability.
Lyophilized vials should be kept refrigerated at 2-8 °C until first use. For long-term storage beyond six months, store at -20 °C in the original sealed vial. Avoid repeated freeze-thaw cycles.
