Core Effects

PT141 is a selective melanocortin receptor agonist . Due to its unique sexual function regulation and central nervous system effects , it is widely used in sexual dysfunction research, neuromodulation and cardiovascular research .

✅ Sexual function regulation :

Activates MC4R receptors to promote sexual desire and arousal

Non- hormonal mechanism , does not affect sex hormone levels

✅ Central nervous system regulation :

Crosses the blood-brain barrier and acts directly on the central nervous system

Regulate appetite and energy balance , affecting metabolic function

✅ Cardiovascular effects :

Transient blood pressure elevation (dose-dependent), requires careful monitoring

Vascular regulation , studying the mechanism of vascular tension

Usage Protocol

1. Recombination method :

Use 1-2mL of bacteriostatic water to inject the peptide lyophilized powder bottle

Gently swirl until completely dissolved, avoid vigorous shaking

Storage after reconstitution : Refrigerate at 2-8°C and use within 24 hours

2. Injection method :

Injection route : Subcutaneous injection (preferred)

Injection site : Abdomen, thighs, or arms, subcutaneous fat layer

Injection dose : 1.0-2.0 mg/time

Injection frequency : Use as needed, no more than once in 24 hours

3. When to use :

Expected effect 4-6 hours before : Slow onset but long-lasting

Use on an empty stomach : Avoid food that affects absorption

Avoid frequent use : Prevent receptor desensitization

4. Dosage regimen :

Starting dose : 1.0 mg to test tolerance

Effective dose : 1.5-2.0mg

Maximum dose : no more than 2.5 mg/24 hours

Duration of effect : 8-12 hours

Storage Guidelines

1. Unrestored :

Temperature : -20°C for long-term storage, 2-8°C for short-term storage

Humidity : Relative humidity ≤ 30%, desiccant protection

Light : Store away from light, in a brown bottle or wrapped in aluminum foil

Expiration date : 36 months at -20°C, 12 months at 2-8°C

2. Storage after reconstitution :

Use Immediately : For best results, use immediately after reconstitution

Store in refrigerator : 2-8°C for no more than 24 hours

Avoid freezing : reconstituted solutions should not be repeatedly frozen and thawed

3. Transport Conditions :

Low temperature transport : ice pack insulation, temperature ≤ 4°C

Shockproof packaging : prevents severe vibrations from affecting the peptide structure

Fast delivery : Delivery within 48 hours to ensure activity

Why choose PT141 ?

Unique mechanism of action , non-hormonal pathway to regulate sexual function

Direct effect on the central nervous system , high research value

The effect is long-lasting and stable , and the single-time effect lasts 8-12 hours
