01The basics

What Andarine S4 by Genetix Pharma is

Andarine, also called S4 or GTx-007, is one of the earliest SARMs (selective androgen receptor modulators). Each Genetix Pharma tablet contains 20 mg, with 50 tablets per bottle. It was developed for muscle wasting and prostate conditions but never progressed through clinical trials.

It’s known for one side effect no other SARM is famous for: changes in vision, especially at night. It also suppresses testosterone. Here’s what you need to know.

03How it works

How it works

  • Partial androgen receptor agonist: it activates androgen receptors in muscle and bone, more weakly than testosterone.
  • Short half-life, about 4 hours, so it’s usually taken in split doses.
  • Eye effects: S4 also binds receptors in the retina, which is thought to cause its vision side effects.

04Clinical reference

Dosing information

Clinical reference. Andarine has no approved or trial-established human dose; it didn’t progress beyond early development.

One Genetix tablet is 20 mg. Vision side effects are reported to become more likely as the dose rises. Talk to a doctor before use.

05Measure it

07Risks

Side effects and risks

There are no published human efficacy trials of S4, so most of what’s known comes from users.

Vision changes

A yellow tint to vision and trouble adjusting to darkness are commonly reported. Don’t drive at night if you notice them; they usually go away after stopping.

Testosterone suppression

Natural testosterone can drop, causing low libido and fatigue.

Cholesterol

HDL commonly falls, as with other androgens.

Liver

Liver injury has been reported with several SARMs. Get a liver panel.

Unknown long-term effects

Long-term safety in people hasn’t been studied.

Don’t use it if you

Are under 18, pregnant or breastfeeding, have eye disease, liver disease or high cholesterol, drive at night for work, or compete in tested sport.

08Interactions

Interactions

Medicines and substances that change how this product behaves, or that it changes. Show this list to your pharmacist along with everything else you take.

  • Good to knowNo interaction studies

    SARMs were never approved, so they were never tested against other medicines.

  • CautionOral steroids, alcohol and acetaminophen

    Liver injury has been reported with SARMs; anything else that loads the liver adds to it.

  • CautionAnything that lowers HDL

    SARMs reduce HDL cholesterol; oral steroids lower it further.

09Bloodwork

Bloodwork checklist

Test before you start, at 4 weeks, and 4 weeks after you stop.

  • Testosterone, LH, FSH
  • Lipid panel
  • Liver panel
  • An eye check if vision changes don’t clear

10After a course

Post-cycle therapy and support

If bloodwork shows suppressed testosterone after a course, post-cycle therapy with a SERM such as tamoxifen (Nolvadex) or clomiphene (Clomid) is commonly used. See Pairs well with below.

Andarine appears to bind to receptors in the eye. The yellow tint and poor night vision usually clear within days to weeks of stopping.

Same compound and strength (20 mg, 50 tablets). The difference is the manufacturer; compare them under Compare brands on this page.

Is S4 banned in sport?

Yes. All SARMs are on the World Anti-Doping Agency’s prohibited list.

How fast is shipping in Canada?

Is S4 legal in Canada?

Andarine isn’t approved by Health Canada, and Health Canada has warned consumers about unauthorized SARM products.
