The detail

What you should know.

Description

HGH 191AA (somatropin) is recombinant human growth hormone with the full 191–amino-acid sequence, identical to the hormone the body produces. It is studied for growth, tissue repair, body composition and sleep quality.

Somatropin is an approved medicine for growth-hormone deficiency in clinical settings; Novapep supplies it strictly for research use.

How it works: HGH acts on growth-hormone receptors and drives the liver to release IGF-1, the main mediator of its effects on cell growth, recovery and fat metabolism.

Researched to support: body composition, recovery and sleep, long horizon.

Quality: Lyophilised (freeze-dried) powder, supplied for research use only. Our manufacturers carry out their own batch testing; we do not independently verify those results or issue certificates of analysis, so we back every order with our purity guarantee instead.

How to use

Reconstitute: Use bacteriostatic water. Add it slowly down the inside wall of the vial and let it dissolve for 10 to 15 minutes. Do not shake.

Administer: Subcutaneous, usually with an insulin syringe.

Dose example: A 5 mg vial reconstituted with 1 ml gives 0.5 mg per 0.1 ml (10 units on a U-100 insulin syringe).

Store: Keep the powder cool and dry. Once reconstituted, store at 2 to 8 °C and use within about 28 days.

These are research materials, not medical advice. Talk to your doctor before use.

Research dosing protocols

In research and clinical contexts HGH is given subcutaneously, typically once daily:

  • Commonly administered in the evening on an empty stomach to align with natural GH release.
  • Morning trainers sometimes shift it to fasted pre-workout.
  • Costed and handled on the 24 IU vial.

Describes dosing used in clinical research, provided as reference only — not a usage recommendation or medical advice. This is an investigational research compound.

Clinical studies

Clinical use: Recombinant somatropin is an approved treatment for growth-hormone deficiency and several other conditions, with decades of clinical data.

Body composition: Research has examined GH for lean-mass, fat-mass and recovery outcomes; benefits are clearest where GH is genuinely deficient.

Status: Supplied strictly as a research compound; not for human use through Novapep.

FAQs
What are peptides?

Peptides are short chains of amino acids (2 to 50) that act as signalling molecules. Ours are supplied for laboratory research.

What's included in my order?

The vial contains lyophilised powder only. You also need bacteriostatic water, a sterile syringe, and a needle. We stock bacteriostatic water under Supplies.

How do I reconstitute the peptide?

Add bacteriostatic water slowly down the inside wall of the vial, then let it dissolve for 10 to 15 minutes. Do not shake.

How should I store it?

Keep the powder cool and dry. After reconstitution, store at 2 to 8 °C and use within about 28 days.

How are peptides administered?

Most are administered subcutaneously with an insulin syringe, for slow, steady absorption. A few formulations use other routes.

When do effects appear?

It varies by peptide and protocol. Some are researched over a few days, others over several weeks.

Do I need to see a doctor?

A prescription is not required, but we recommend speaking with your doctor, especially if you have a medical condition or take other medication.

Are your peptides tested?

Our manufacturers carry out their own batch testing, but we do not test independently and do not hold certificates of analysis — so we make no purity claim of our own. We back it with a guarantee instead: if you want a vial independently tested, contact us first, we’ll agree a laboratory and pay for the test. If the result doesn’t match the label, we cover the testing cost and replace the product.
