STUD 100 (Lidocaine)

Premature Ejaculation (PE) is one of the most common male sexual disorders. STUD 100 (Lidocaine) is a classic topical medication in spray form, containing Lidocaine (typically 9.6%). It is used to reduce excessive sensitivity, which provides significantly greater control over ejaculation and prolongs the duration of intercourse.

What is STUD 100 (Lidocaine)?

STUD 100 is a topical medication in the form of a metered-dose spray. Its active component is Lidocaine, a powerful local anesthetic of the amide type.

1. Indication and mechanism of action

• Indication: Treatment of lifelong (primary) and acquired (secondary) premature ejaculation.

• Mechanism of Action: Lidocaine temporarily blocks sodium channels in the membranes of nerve endings. This leads to a controlled reduction in sensitivity of the glans penis (the most sensitive area). Reduced sensitivity slows down the transmission of nerve signals to the brain, effectively increasing the Intravaginal Ejaculatory Latency Time (IELT).

2. Advantages of the local anesthetic

• Minimal Systemic Risks: Since STUD 100 acts only locally, it is virtually unabsorbed into the systemic circulation in significant amounts, which minimizes the risk of systemic side effects (nausea, dizziness) associated with oral medications (Dapoxetine).

• Fast Effect: Action begins very quickly, within 5–15 minutes after application.

Instructions for using STUD 100 (Lidocaine)

Correct application of STUD 100 spray is critically important for efficacy and partner safety.

1. Dosage and method of application

• Dosage: The number of sprays is strictly individual. Start with the minimal dose (2–4 sprays). Never exceed the maximum number of sprays indicated in the instructions (typically 10–20 sprays per single act of intercourse).

• Method: Spray onto the glans penis and, if necessary, the most sensitive part of the shaft.

• Timing: Apply 10–15 minutes before sexual intercourse.

2. Critical step — removing the anesthetic

• Mandatory: Before starting intercourse, you must thoroughly wash off the residual spray with warm water or use a condom. Failure to do so may result in Lidocaine transfer to the partner, causing undesirable numbing of the vaginal mucosa, which will impair her sensation.

• Reapplication: Do not reapply the spray within a short period.

Critical contraindications for STUD 100 (Lidocaine)

Despite local action, restrictions related to Lidocaine exist.

• Allergy: Individual hypersensitivity or allergy to Lidocaine.

• Skin Damage: Do not apply to damaged, irritated, inflamed, or traumatized skin on the penis.

• Systemic Conditions: Use cautiously in cases of severe liver, kidney, or cardiovascular diseases.

Side effects of STUD 100

Side effects are usually local in nature:

• Common: Excessive reduction in penile sensitivity (if too much spray is applied), which may make it difficult to maintain an erection.

• Less Common: A slight burning sensation or irritation at the application site.

• Risk to Partner: Temporary numbing of the mucosa if the spray was not washed off or used without a condom.

Professional advice on using STUD 100 (Lidocaine)

1. Individual Dose Titration: Start with the minimal number of sprays (2–3) and gradually increase until you find the optimal amount that provides control but preserves enough sensation for pleasure.

2. The "Apply-Wait-Wipe" Technique: Apply the spray, wait 10–15 minutes, then wipe off the residue. This method is the safest for the partner while retaining the prolongation effect for you.

3. Not for ED: STUD 100 is intended only for PE treatment. If you have problems with erection firmness, it should be combined with oral PDE5 inhibitors.

STUD 100 (Lidocaine): Extended Q&A section

• How long does STUD 100 prolong intercourse? With correct application, the spray can increase the Intravaginal Ejaculatory Latency Time by 3–5 times or more, depending on individual sensitivity.

• Can STUD 100 be used with erection pills? Yes, this is a safe and effective combination. First, take the erection pill (Tadalafil or Sildenafil), and then use the spray for prolongation.

• What is the advantage of STUD 100 over Dapoxetine? The main advantage is its local action, which allows avoiding systemic side effects (nausea, drowsiness) associated with Dapoxetine.

• Can the spray cause loss of erection? If an excessive amount of spray is applied, sensitivity may be reduced too much, which can make it difficult to maintain an erection. In this case, the dosage must be reduced.
