  6. Aaron Mitchell

  7. Isaiah Wood

    No side effects

  8. David Clark

    I ran S4 at 25mg per day spilt into two doses (Thinking it would keep the cycle steady). Within the first couple of weeks my muscles looked noticeably drier and strength held up surprisingly good even on a calori deficit. About the famous “Yellow tint” from it, I mean yeah what do yall expect but it wasnt half as bad as everyone describes it. It comes with good benefits, plus once I finished the cycle the tint disappeared.

Cutting Optimization

Andarine S4 works by selectively binding to androgen receptors in muscle and bone tissue, promoting anabolic activity while supporting fat oxidation. This dual action makes it particularly effective for cutting phases where maintaining muscle while losing fat is crucial.

The compound increases protein synthesis and prevents muscle catabolism during caloric restriction, while simultaneously enhancing lipolysis and fat burning. S4’s unique properties also improve vascularity and muscle hardness, creating a more defined appearance.

With a half-life of 4-6 hours, Andarine provides consistent support when taken multiple times throughout the day, making it highly effective for cutting goals.

Frequently Asked Questions

What is Andarine S4?

Andarine S4 is a selective androgen receptor modulator designed for cutting, fat loss, and muscle preservation.

Is S4 good for cutting?

Yes, S4 is excellent for cutting phases as it helps preserve muscle mass while promoting fat loss and improving muscle definition.

Can I use S4 for muscle building?

While primarily a cutting SARM, S4 can support lean muscle gains, especially when combined with proper nutrition and training.

What results can I expect from S4?

Users typically experience enhanced fat loss, improved muscle definition, better vascularity, and preserved muscle mass during cuts.

What are the side effects of Andarine?

Users have occasionally reported changes in vision, mild fatigue, or hormonal fluctuations. These effects are anecdotal and vary by individual.

Do I need to cycle Andarine S4?

Yes, follow recommended cycle lengths with breaks to maintain effectiveness and allow your body to recover.

How to take Andarine S4?

Andarine (S4) is typically taken once or twice daily due to its shorter half-life of around 4-6 hours. Most users divide their daily dosage into two equal parts, one in the morning and one in the evening, to maintain stable levels in the body. The usual dosage ranges from 25 mg to 50 mg per day, depending on experience and fitness goals. Always start with a lower dose to gauge tolerance and adjust gradually.

When should I take Andarine S4?

For best results, take Andarine S4 at consistent times each day, ideally with meals to improve absorption. If you’re splitting doses, take half in the morning and half in the evening. Consistency is key for maintaining optimal plasma concentration and achieving steady performance and physique gains throughout your cycle.

How long does Andarine stay in your system?

Andarine (S4) has a half-life of approximately 4-6 hours, meaning it remains active in the body for about 24-36 hours after the last dose. However, complete elimination from the system may take 2-3 days, depending on dosage, frequency, and individual metabolism. Because of its shorter half-life, split dosing is preferred to maintain stable results and reduce fluctuations in energy or vision-related side effects.
