Andarine S4, also known as acetamidoxolutamide, is a research chemical that belongs to a class of investigational compounds called selective androgen receptor modulators, or SARMs. It is designed to have similar effects as testosterone and anabolic steroids, but with higher tissue selectivity.
I first learned about SARMs like Andarine S4 when researching performance-enhancing compounds online. After extensively reading about the potential benefits and side effects, I decided to purchase some Andarine S4 in liquid form to trial.
Andarine S4 is reported to increase muscle mass and strength. It binds to androgen receptors in muscle and bone selectively over the prostate, sebaceous glands, and other tissues. This improves its safety profile. It is not approved for human use or consumption, given a lack of long-term safety data.
Why do people use Andarine S4 Sarm?
Despite the lack of clinical trials, people use Andarine S4 for the following experimental reasons:
- Increase lean muscle mass: The primary use is boosting muscle growth by binding to skeletal muscle androgen receptors.
- Enhance strength: It boosts muscular strength levels, allowing users to lift heavier weights and build more muscle.
- Fat loss: Andarine S4 is said to help burn visceral and subcutaneous fat, particularly when stacked with cardarine.
- Athletic performance: improved strength, endurance, and accelerated recovery may boost athletic capabilities.
- Recomposition: Adding muscle and losing fat can radically transform the physique. S4 allows “cutting” without losing muscle.
I opted to trial Andarine S4 in the hopes it could improve my lean muscle gains. The purported ability to build strength and size without unwanted side effects appealed to me.
Benefits of Andarine S4 Sarm:
User reports suggest Andarine S4 may provide benefits, including:
- Improved strength: Users often become stronger within just a couple weeks of use. Heavy compound lifts can be pushed to new limits.
- Lean muscle gains: Good amounts of quality lean muscle can be gained without excessive bulking or water retention.
- Enhanced stamina: Many users note significantly improved cardiovascular endurance and workout stamina.
- Fat loss: Andarine S4 is said to help mobilize and reduce the overall body fat percentage, especially around the midsection.
- Muscle preservation: Retaining muscle while cutting is enabled by the highly anabolic effects.
- Joint healing: Some users report improvement in joint pain and mobility, allowing better workouts.
When trialing my newly purchased Andarine S4 I was very pleased with the strength and endurance boost it provided during my gym workouts. I soon progressed to lifting heavier weights than ever before.
What are some of the possible side effects of Andarine S4 Sarm?
Despite being selective in its action, some potential Andarine S4 side effects may include:
- Eyesight changes: most commonly, a temporary yellow tint to vision and decreased night vision due to the action on eye receptors.
- Testosterone suppression: can suppress natural testosterone production, requiring post-cycle therapy.
- Liver strain: oral doses may raise liver enzymes, so cycle length and doses must be limited.
- Increased aggression: Some increased irritability and aggression are possible.
- Hair loss: Those prone to male-pattern baldness may experience accelerated hair loss.
- Acne: Hormonal changes can cause acne outbreaks in some people, especially at higher doses.
During my trial of Andarine S4, I did experience visual changes like yellowish-tinted vision. I also had bloodwork done to monitor any liver enzyme elevation. Thankfully, the effects reversed fully after my cycle finished.
Dosage of Andarine S4 Sarm:
Typical Andarine S4 doses range from:
- Cutting: 25–50 mg per day for up to 8 weeks. Start low at 25mg daily.
- Bulking: 50–75 mg per day is often used for gaining muscle. Do not exceed 75mg daily.
- Women: 5–10 mg per day is recommended for female users.
Andarine S4 has a half-life of 4-6 hours, so it is usually split into two even doses per day. It is often stacked with other SARMs, like Ostarine, for further benefits.
For my first Andarine S4 cycle, I opted for 50mg per day split into 25mg twice daily doses. I limited my cycle length to 6 weeks with a mini PCT afterwards to restart testosterone.
Where to Buy Andarine S4 Sarm Online
Due to the legal gray area, buying SARMs like the Andarine S4 online can be tricky. Disreputable sellers may mislabel, include fillers, or sell tainted products. To reduce risks, I recommend:
- Reputable SARMs websites: Purchase from trusted online Buy Peptides USA with plenty of reviews and lab testing.
- Buy Peptides USA: A licensed company offering high-purity, third-party-tested SARMs Reliable quality.
I opted to purchase my liquid Andarine S4 from Science.bio after verifying their stellar reputation. The product’s quality was verified by lab certificates.
In summary, Andarine S4 is an investigational SARM designed to boost muscle growth and strength while promoting fat loss. Though not approved for human use, bodybuilders and athletes use compounds like Andarine S4 for their purported benefits. Significant side effects are possible, however, so thorough research is required before use. Reputable online sellers can provide quality SARMs, but legality varies globally, so local laws should be checked. With proper dosing and cycle length, compounds like Andarine S4 may provide notable changes in physique and strength.
