HGH 191AA (Somatropin）
Somatropin is a recombinant human growth hormone composed of 191 amino acids, matching the structure and biological properties of endogenous pituitary-derived growth hormone. It is evaluated in controlled laboratory settings for its influence on cellular growth, protein synthesis, and metabolic signaling via growth hormone receptors and downstream IGF-1–mediated pathways.
Experimental applications involve studies of skeletal and muscle biology, hepatic and adipose metabolism, regenerative models, and endocrine system regulation. Investigators monitor changes in cellular proliferation, nutrient utilization, and pathway activation associated with anabolic and metabolic outcomes in vitro and in vivo research systems.
Overview
Somatropin supports diverse research areas, including growth hormone deficiency modeling, metabolic homeostasis, mitochondrial efficiency, and tissue rebuilding under physiological or stress conditions. Analyses frequently focus on muscle mass maintenance, bone structure, lipid mobilization, and biochemical mechanisms driving adaptive remodeling responses in laboratory environments.
Chemical Makeup
Somatropin is a single-chain polypeptide hormone with 191 amino acids. A standard molecular formula is applicable; however, for this batch, mass spectrometric confirmation is listed to verify analytical identity.

We make our peptides in our own cGMP lab. Watch the video to see how every vial is produced, tested, and handled with care.
Science Behind Our Peptides
A clear explanation of how our peptides work, their benefits, why quality matters for best results, and what you should know.

How do I know the peptides I order are exactly what the label says?
Every vial we sell comes from a lab that follows current Good Manufacturing Practices (cGMP). That means each step of production is documented and controlled. Before a batch is released, it’s tested by independent third-party labs for purity, identity, and sterility. Certificates of analysis are available so you can see the exact test results.
Are your peptides produced in a sterile and controlled environment?
Yes. The labs we work with use ISO-certified clean rooms where air quality, equipment, and handling procedures are tightly regulated. Staff are trained to pharmaceutical-grade standards. This ensures the peptides are produced in an environment that minimizes contamination risks.
What about shipping? Do the peptides remain stable in transit?
Peptides in lyophilized (freeze-dried) form are stable at room temperature for transport. Once you receive them, refrigeration is recommended to maintain long-term integrity. We package every order securely to prevent damage and ship promptly, so your vials arrive in optimal condition.
How do I know you actually make these peptides yourselves?
We operate under strict in-house protocols that follow current Good Manufacturing Practices (cGMP). That means our team oversees the entire process from sourcing raw amino acids to the final lyophilized vial. Nothing is outsourced or repackaged. This gives us full control over purity, consistency, and sterility, and it’s why we can stand behind every single vial we ship.
What should I do with the vials once they arrive?
Store them in the refrigerator, away from direct light and heat. If you need to keep them longer, some peptides can be stored frozen. Each vial comes with clear handling instructions so you know the proper conditions for stability.
What proof do you have that your peptides are legitimate?
The strongest proof is transparency. For every peptide, we can provide certificates of analysis, manufacturing documentation, and references to the published scientific research behind it. If you ever have questions, we’ll show you the data rather than ask you to take our word for it.
