4-AD Liquid – Potent Testosterone Precursor in Suspension Form

4-AD Liquid is a fast-absorbing oral prohormone suspension designed to act as a direct testosterone precursor. By converting into active testosterone in the body, 4-AD helps drive muscle growth, strength gains, and improved recovery, making it a staple in many bulking and strength-focused cycles.

What is 4-AD Liquid and How Does It Work?

Unlike capsules, 4-AD in liquid suspension form offers rapid absorption and higher bioavailability. Once consumed, 4-AD (Androstenedione) is metabolized into testosterone, which binds to androgen receptors in muscle tissue. This results in enhanced protein synthesis, nitrogen retention, and greater anabolic activity, leading to noticeable size and strength improvements.

According to Wikipedia’s article on Androstenedione, this compound has long been recognized as a testosterone precursor, and in liquid form it offers faster delivery compared to tablets.

Key Benefits of 4-AD Liquid

• Boosts natural testosterone levels through precursor conversion

• Promotes muscle mass and rapid size gains

• Increases strength, endurance, and recovery

• Fast-acting liquid suspension for superior absorption

• Can be stacked with Nanodrol, Epistane, or Testosterone blends for advanced cycles

How to Use 4-AD Liquid Effectively

Typical use is 2–4 mL daily, split into multiple doses for optimal blood level stability. A cycle length of 4–6 weeks is common, after which users transition into Post Cycle Therapy (PCT) with products like Nolvadex or Clomid.

4-AD Liquid is often stacked with Nanodrol or Liquid Epistane for mass-building, or paired with cutting agents like Winni-V for leaner cycles.

FAQs for 4-AD Liquid

Q1: What is 4-AD Liquid?
A: 4-AD Liquid is a prohormone suspension designed as a testosterone precursor. It helps increase muscle size, strength, and recovery when used in a bulking cycle.

Q2: How does 4-AD work in the body?
A: 4-AD (Androstenedione) converts to testosterone once ingested, supporting anabolic activity, protein synthesis, and muscle growth.

Q3: What is the recommended dosage?
A: Most users take 2–4 mL daily, split across doses, but dosage depends on brand formulation.

Q4: Can it be stacked with other products?
A: Yes, it is often stacked with Nanodrol, Epistane Liquid, or Test-based compounds for mass-building cycles.

Q5: Does it require PCT?
A: Yes. As with most prohormones, Post Cycle Therapy (PCT) is recommended to restore natural testosterone production.
