Description

What is S4 25 (Astera Labs)?

Astera Labs andarine in 25mg tablets, 50 to a sachet. Hard and dry at the end of a cut, run at a modest dose in a short block.

Also sold as andarine, S4 or S-4.

Andarine is one of the older SARMs and it produces a hard, dry look rather than size, which is why it sits in cutting phases. It binds the androgen receptor selectively in muscle and bone, and it clears quickly, so it is typically used in short blocks at the end of a cut rather than run for months.

S4 (Astera) benefits

Produces a hard, dry look with no water at all
Preserves lean tissue through a deficit
Noticeable improvement in vascularity and definition
Short half-life, so it clears quickly if it does not suit you
Useful in the final weeks of a cut rather than through a bulk
25mg tablets, which halve to the 12.5mg most people find tolerable

S4 dosage

Starting dose: 12.5mg per day, half a tablet
Common range: 25 to 50mg per day
Timing: Split across the day, or morning only
Cycle length: 6 to 8 weeks
Post-cycle therapy: Required, plan it before you start
Half-life: About 4 hours

Start at half a tablet. The side effects scale directly with dose and 12.5mg is comfortable for many people where 50mg is not.

Many people dose in the morning only, which suits the short half-life.

Who is S4 (Astera) for?

People in the last weeks of a cut who want hardness and dryness.

S4 25 is the same strength from Deus Medical, and the Biaxol capsules add black pepper extract.

Before you run it. SARMs suppress your own testosterone and they need post-cycle therapy. The idea that they do not is the most expensive piece of misinformation in this category. They are more selective than steroids, which means fewer androgenic side effects, not an absence of suppression. Plan post-cycle therapy before you start and get bloodwork before and after, including lipids and liver markers, both of which SARMs move. Andarine has one of the harder side effect profiles in this category, and they are dose related, which is why it is usually run at a modest dose in short blocks rather than pushed. Temporary changes to vision are the one people most often mention; they settle once you stop. Start low, see how it suits you before increasing, and keep the run short. Not for anyone under 18, and not for women who are pregnant or breastfeeding.

How to use S4 (Astera)

Swallow with water, split across the day or taken in the morning only. Start low and increase only if it suits you.

Frequently asked questions

Do SARMs really need PCT?

Yes. This is the single most repeated piece of bad advice about them, and it costs people months of feeling flat while they wait for something to recover on its own.

SARMs are selective, not non-suppressive. They act on the androgen receptor and your body responds by shutting down its own production. A SERM such as tamoxifen or clomiphene is what restarts it.

How do I keep the side effects manageable?

Keep the dose modest and the run short. Andarine's side effects are clearly dose related, so 12.5mg is comfortable for a lot of people where 50mg is not.

Splitting the dose across the day, or taking it in the morning only, is what most people settle on. If it does not suit you at a low dose, it is not going to at a higher one.

How long can I run it?

Six to eight weeks, and shorter is common. Andarine is a finishing compound rather than something to build a whole cycle around.

The short half-life means it clears quickly if you decide it does not suit you, which is one of its practical advantages.

What is it best used for?

The last weeks of a cut, where hardness and dryness matter and you are not trying to add anything.

It is a poor choice for a bulk. Andarine does not add size and running it for that reason is how people conclude it does nothing.

Andarine or ostarine for a cut?

Ostarine if the goal is holding what you have built while calories are low. It is the gentler of the two and it is the one to start with.

Andarine if you are already lean and want hardness and dryness in the final weeks. They do different jobs and a lot of people run ostarine through the cut and add andarine at the end.
