About HGH 191AA 15IU
HGH 191AA (Somatropin) 15IU
HGH 191AA (Somatropin) is recombinant human growth hormone produced as the full 191-amino-acid sequence, and one of the most established reference proteins in growth-hormone-axis research. This listing supplies the 15IU lyophilized vial for laboratory research use. Every batch is tested to at least 98% purity by HPLC with a certificate of analysis (COA), is USA-made and third-party verified. For research use only; not for human or veterinary use or consumption.
Mechanism of Action
HGH 191AA is the intact 191-amino-acid recombinant growth hormone. In the literature it is used as the baseline intact-hormone reference against which growth hormone secretagogues such as Ipamorelin and GHRH analogs such as CJC-1295 are compared. This describes a research context only.
Preclinical Research
Recombinant somatropin is one of the most studied reference proteins in endocrinology. In this research it is used as the intact-hormone comparator in growth-hormone-axis and cellular studies. All referenced work is preclinical and mechanistic; no human data or outcomes are implied.
Research Applications
Typical applications include comparative growth-hormone-axis studies alongside secretagogues and GHRH analogs. Browse the full growth & musculoskeletal research range for related material. See our HGH 191AA research overview article for background.
Protocol & Handling
This is a lyophilized (freeze-dried) vial. Reconstitute in the laboratory before study using a suitable diluent such as bacteriostatic water. Store the sealed vial frozen; keep reconstituted material refrigerated and protected from light. Handle only in a controlled laboratory setting. For research use only, not for human or veterinary use or consumption.
Frequently asked questions
What is HGH 191AA (Somatropin)?
HGH 191AA (Somatropin) is recombinant human growth hormone produced as the complete 191-amino-acid sequence, used as a reference protein in growth-hormone-axis research and supplied strictly for laboratory research use.
What does "191AA" mean?
It refers to the full 191-amino-acid chain of the intact hormone, distinguishing it from shorter fragment analogs.
How is it different from secretagogues like Ipamorelin or CJC-1295?
Those are GHRH analogs and secretagogues that act upstream on the growth-hormone axis; HGH 191AA is the intact hormone itself.
Does it need to be reconstituted?
Yes. It is a lyophilized vial and is reconstituted in the laboratory before study using a suitable diluent such as bacteriostatic water.
How should it be stored?
Store the sealed lyophilized vial frozen for long-term stability. Once reconstituted, keep refrigerated and protected from light.
What purity is it tested to?
Each batch is tested to at least 98% purity by HPLC and ships with a certificate of analysis (COA). USA-made and third-party verified.
What is it studied alongside?
Commonly alongside growth hormone secretagogues (Ipamorelin, CJC-1295, Sermorelin) as a baseline intact-hormone reference.
Is it intended for human use?
No. It is sold strictly for laboratory and research use only, and is not for human or veterinary use, consumption, diagnosis or treatment.
