Our peptides are manufactured under strict quality and control standards. Each product is delivered in lyophilized form , which ensures stability and prevents quality deterioration during transportation, even under adverse conditions . We test every batch.

We do not offer ready-made aqueous solutions because in them the peptide molecules are significantly less stable . The presence of water accelerates processes such as hydrolysis , oxidation and aggregation , which leads to a gradual loss of activity and effectiveness of the peptides.

Even under optimal conditions, the shelf life of peptide solutions is limited to about 4 weeks . Unlike aqueous solutions, the lyophilized form preserves the structure and biological activity of the peptides for a long period - up to 24 months under refrigerated conditions and up to 4 months at room temperature.

When stored in a refrigerator at 2°C – 8°C, the shelf life is up to 24 months . If kept at room temperature , stability is maintained for approximately 3–4 months .

After reconstitution, the peptides are in a more unstable form and should be stored in the refrigerator for up to 4 weeks.

At PurePeptide, we provide fast and secure delivery. Orders are processed within 1–3 business days and delivered to your address in less than a week.

Standard delivery time is 3–7 days , with most shipments arriving within 2–3 days . After shipment, you will receive a confirmation email.

With us, you can rest assured that your order will arrive quickly, reliably, and in excellent condition.

Work in a clean environment and use sterile supplies .
Cool the peptide and bacteriostatic water in the refrigerator.
Using a sterile syringe, withdraw the required volume of bacteriostatic water .
Point the needle towards the inner wall of the vial with the lyophilized substance and slowly add the bacteriostatic water.
Gently swirl the vial until the powder is completely dissolved.
Store the reconstituted solution in a refrigerator at 2–8°C. Its shelf life under these conditions is 4 weeks .

What is hGH Frag 176-191?

Name: hGH fragment 176-191 5mg
Brand: PurePeptide
SKU: PP-HGH-FRAG-5MG

Availability: InStock

hGH Fragment 176-191 is a synthetic peptide, a modified fragment (amino acids 176-191) of the C-terminal part of human growth hormone (hGH). It was created with the aim of isolating the lipolytic (fat-breaking) properties of GH without activating its other physiological effects. In the scientific literature, hGH Frag has been studied as a potential regulator of lipolysis and metabolic balance.

Unlike full-length growth hormone, HGH Frag 176-191 does not show significant activity on IGF-1 levels and does not stimulate tissue growth. Instead, according to scientific studies, the peptide has been associated with stimulation of lipolysis and inhibition of lipogenesis, making it an interesting model for studying metabolic processes related to fat metabolism.

HGH Frag Observations 176-191

In the scientific literature, HGH Frag 176-191 has been studied in relation to:

Stimulation of lipolysis - promotes the breakdown of fatty acids in adipocytes
Inhibition of lipogenesis - suppresses the accumulation of new fat cells
Body weight regulation - being studied as a potential metabolic modulator
Maintaining lean muscle mass - without anabolic effects typical of GH
Visceral fat reduction - in obesity models
Improvement in insulin sensitivity - observed in some preclinical studies

Scientific data

HGH Frag 176-191 has been studied in primarily preclinical models and limited clinical trials. Key scientific observations include:

Increased lipolysis in adipocyte cultures and living models
Reduction in total and visceral fat without change in IGF-1 levels
Lack of effect on glucose homeostasis at low doses
No effect on organ and tissue growth
Improved lipid metabolism and energy efficiency in some experimental models

Dosage and administration

In the scientific literature, doses quoted range from 250-500 μg daily, administered subcutaneously, often divided into 1-2 applications. The peptide is typically used in short-term research cycles (2-4 weeks) focused on lipolytic mechanisms.

At 5 mg + 3 ml bacteriostatic water:

Concentration = 1.67 mg/ml → 0.06 ml = 100 μg

Example values:

0.06 ml = 100 μg

0.12 ml = 200 μg

0.18 ml = 300 μg

0.24 ml = 400 μg

Application in sports and research settings

HGH Fragment 176-191 is included in the WADA list of controlled substances and is not permitted for use by professional athletes. In a research context, the peptide is used to study lipolytic mechanisms and energy metabolism in various models of metabolic syndrome, obesity, and insulin resistance.
