HGH (Somatropin 191aa) — Research Kit

Description

What is HGH (Somatropin)?

Human Growth Hormone (HGH), or somatropin, is a recombinant 191-amino-acid single-chain polypeptide identical in sequence to the growth hormone produced by the anterior pituitary gland. It is one of the most extensively investigated proteins in endocrine, metabolic, and longevity research, acting at the growth hormone receptor (GHR) to influence IGF-1 production, protein synthesis, lipid metabolism, and tissue growth.

It is supplied by Revial Labs as a lyophilised (freeze-dried) powder for reconstitution in bacteriostatic water. All product is intended strictly for laboratory research use.

Areas of Research Investigation

Published research on recombinant HGH has been conducted primarily in animal and cell-culture models. Areas of research investigation include:

• GH/IGF-1 axis studies — investigation of growth hormone receptor binding kinetics and downstream IGF-1 signalling in cell and animal models.
• Metabolic research — preclinical studies of lipolysis, protein synthesis, and glucose metabolism.
• Tissue repair and regeneration — research into connective tissue, bone mineralisation, and cellular repair pathways.
• Age-related decline models — study of age-dependent GH sensitivity and somatotroph secretion in comparative animal designs.

This is a summary of published research directions and should not be interpreted as claims about the compound’s effects in humans.

Reconstitution

HGH is reconstituted in bacteriostatic water for research purposes. For step-by-step guidance, see our article How to Reconstitute Research Peptides, or use our Peptide Reconstitution Calculator.

Storage and Handling

• Before reconstitution: Store at 2–8°C (refrigerator) for long-term storage. Short-term room-temperature storage is acceptable during shipping.
• After reconstitution: Store the solution at 2–8°C and use within the recommended period.
• Avoid: Direct sunlight, freeze-thaw cycles, and repeated agitation.

Frequently Asked Questions

What is included with this product?

Sealed vials each containing 24IU of lyophilised HGH powder (quantity depending on the kit option selected). The 120IU and 240IU kits include matching bacteriostatic water (5 and 10 vials respectively) for reconstitution. Syringes and alcohol swabs are sold separately — see our Starter Accessory Pack. For single vials, bacteriostatic water can be added from our Bacteriostatic Water product page.

How pure is Revial Labs HGH?

All HGH supplied by Revial Labs is manufactured to ≥99% purity and independently verified by High-Performance Liquid Chromatography (HPLC). A batch-specific Certificate of Analysis is available on request.

What is the difference between the kit sizes?

All vials are identical 24IU vials. The single vial contains 24IU, the 120IU kit contains five vials (120IU total), and the 240IU kit contains ten vials (240IU total). Larger kits offer a lower per-vial cost.

How is HGH shipped?

Orders are dispatched via Royal Mail tracked delivery from the UK, typically within one working day. Refrigeration is recommended once received.

Is a Certificate of Analysis included?

A batch-specific COA verifying identity, purity, and mass spectrometry is available on request. Contact us with your order number and we will send the corresponding document.
