S4 (Andarine) Redback Sarms Australia


S4 (Andarine) acts as an orally active partial agonist of the androgen receptors. As a matter of fact, one study showed it reduced prostate weight as much as finasteride does, but without the anti-androgenic side effects or reduction in muscle mass. This is an important fact since it shows that S4 helps block dihydrotestosterone (DHT) by binding to target receptors without harming muscle gains like a 5a-reductase inhibitor (such as finasteride or dutasteride) would do. Consequently, Andarine could help you keep your head hair while using anabolic steroids, and help you avoid the nasty side effects of a drug like finasteride.

Furthermore, just like all SARMS, Andarine will attach to the androgen receptors without causing androgenic activity in non-skeletal muscle tissues. In fact, it is estimated that Andarine will attach about half as potently as straight testosterone, but it will not cause the androgenic side effects seen with the latter one. Therefore, this is not only great for females, but it’s also great for those males who do not want to deal with androgenic side effects.

Main Uses –  Vascularity, Strength, Recomping
Dose (Beginner) – 40mg per day (4 levelled off micro scoops) 5 days on, 2 days off. This will last for 50 days
Dose (Experienced) – 60mg per day (6 levelled off micro scoops) 5 days on, 2 days off. This will last for up to 25 days.
Half-Life – 6 hours
Cycle For – 8 weeks


How & When to Take – Andarine is recommended at doses of 20-40mg a day and has even been tolerated at 100mg, although it is highly recommended to start low and gradually increase dosage to keeps side effects minimal. It has a half-life of 6 hours, so I recommend you dose Andarine (S4) at least twice a day (2 scoops in the morning and 2 in the afternoon for 40mg dosage). The optimum length of Andarine cycles are said to be up to 8 weeks long and is not hepatotoxic, so unlike oral steroids and comparable drugs, longer cycles do not cause danger to the liver.

Benefits of S4:

⋅ Lean Muscle Gains
⋅ Fatburner
⋅ Increased Vascularity
⋅ Improve Muscle and Bone Growth
⋅ Strength Gains
⋅ Increase Endurance

Side Effects:
Andarine does not aromatize, so no estrogenic side effects take place when using it. What’s more, it is mildly suppressive – the suppression is around 20-30% vs. the 95% seen with most anabolic steroids. Besides, it does not cause such androgenic side effects as heart strain, and it does not affect the liver.

However, S4 has one side effect that is very interesting – it interacts with the androgen receptors in the eyes, and while it is in your system you may have trouble adjusting your eyes from darkness to light, and also notice a yellow tint (especially at night). Nonetheless, this is only an issue while the compound is in your system, and once you stop taking it this side effect will go away in a matter of days. For this reason, some users choose to run a lower dosage when this happens, or they will take a couple days off when the issue arises.

5 ON/2 OFF:
For users who experience unwanted vision side effects with S4, I suggest you use it 5 days on 2 days off. This means you use Andarine (for example) Monday through Friday and take Saturday/Sunday off. This will allow your system to expel the extra s4 and help you start over fresh on Monday.
