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 PT-141 (Bremelanotide)?

Name: PT-141 (Bremelanotide) 10mg
Brand: PurePeptide
SKU: PP-PT141-10MG
Price: 49.00 EUR
Availability: InStock

PT-141, also known as Bremelanotide, is a synthetic peptide from the group of melanocortin agonists, developed as an analogue of α-MSH (α-Melanocyte-Stimulating Hormone). In Studies have observed activation of the melanocortin receptors MC3R and MC4R in the central nervous system, which is associated with regulation of sexual function, energy balance, and neuroendocrine response.

PT-141 differs from Melanotan II in that it primarily targets central neuroregulation rather than peripheral effects such as melanogenesis. In research settings, it has been used as a model to study neuromodulation of sexual behavior, vasodilation, and the hypothalamic-pituitary axis, as well as a potential link to libido and mood.

Observations on PT-141

In the scientific literature, PT-141 has been studied in relation to:

Regulation of sexual function - activation of MC4R in the central nervous system
Neuromodulation of libido - influencing dopamine and endorphin pathways
Effect on vasodilation and blood flow in the genitals
Regulation of energy balance and appetite
Studies of the melanocortin system and its interaction with other neurotransmitters
Potential role in stress adaptation and central fatigue

Scientific data

PT-141 has been studied in preclinical and limited clinical models for its effects on sexual reactivity and neurochemical mechanisms:

Activates MC3R and MC4R receptors, leading to stimulation of neuronal pathways associated with libido
In live models it has shown improved sexual motivation and frequency of copulatory behaviors
Increased sexual interest and arousal observed in human studies
Does not directly affect the cardiovascular system or the hormonal levels of GH and IGF-1
It is being studied as a potential neuromodulator of the hypothalamic-pituitary axis.

Dosage and administration

The scientific literature on PT-141 typically cites doses between 500 and 2000 μg administered subcutaneously, depending on the study design. Due to its central action, effects occur relatively quickly, within 30 to 120 minutes. Studies have used both single applications and short series.

At 10 mg + 3 ml bacteriostatic water:

Concentration = 3.3 mg/ml → 0.15 ml = 500 μg

Example values:

0.15 ml = 500 μg

0.30 ml = 1 mg

0.45 ml = 1.5 mg

0.60 ml = 2 mg

Possible side effects

In research settings, PT-141 is considered well tolerated. Mild and transient reactions have been reported in published studies, including:

mild nausea or dizziness
transient increase in blood pressure
facial flushing or feeling of warmth
changes in sexual motivation in experimental models
fatigue or mild drowsiness after application

Most reactions were described as transient, dose-dependent, and resolved within a few hours. No serious adverse effects were reported at study concentrations.
