Andarine S4

Andarine S4 is a selective androgen receptor modulator (SARM), taken orally rather than injected, sold here as 15mg capsules by iMuscle. It binds selectively to androgen receptors in muscle and bone tissue, which is why users typically report lean muscle retention, added hardness and fat loss. Its main use is during a cutting phase, where the goal is holding onto strength and muscle while eating in a calorie deficit. This is general guidance, not medical advice.

A common approach for first-time users is one capsule a day for the first week, then two capsules a day for the rest of an 8 week cycle if the first week is well tolerated, taken at roughly the same time each day. Doses should be adjusted to the individual, and this is a guide rather than medical advice, so check your plan with a doctor before starting.

The most reported issue with Andarine is a temporary change to vision, such as a yellow tint or slower adjustment to darkness, which tends to resolve after stopping. It can also suppress natural testosterone, cause a mild rise in liver enzymes, and lower HDL cholesterol, so a liver support product is generally recommended throughout the cycle. Baseline bloodwork covering testosterone, oestradiol, LH, FSH, lipids and liver enzymes is worth doing before starting, then again partway through and after the cycle.

Yes. Because Andarine suppresses natural testosterone production, PCT is generally recommended and should start around 2 days after the last dose. Nolvadex at 20mg a day for 4 weeks is a common approach, with Clomid at 50mg a day for 4 weeks as an alternative, and no taper is needed at the end of either protocol. Confirm your own PCT plan with a doctor.

Some users add a low, supportive dose of testosterone, around 100 to 150mg per week, to help offset the suppression that comes with an Andarine cycle. Cardarine (GW-501516) is not a SARM, it is a PPAR-delta agonist that works on a different pathway to support endurance and fat loss, which is why it is often stacked alongside Andarine rather than used in place of it. Any stack should be planned around bloodwork and personal tolerance rather than assumed to suit everyone.
