What is Narrows Labs 4-Andro Xtreme?

Narrows Labs 4-Andro (4-Androsterone) is a wet, potent anabolic agent which changes into testosterone via a two-step transformation upon absorption. It is a non-methylated prohormone, which means it has minimal effects or stress on the liver and organs of the user.

How Does Narrows Labs 4-Andro Xtreme Work?

After being consumed, Narrows Labs 4-Andro enters your bloodstream and converts into testosterone. The compound will start to have a noticeably high anabolic behaviour, resulting in size and strength increases while enhancing your sex drive – giving you that incredible “Alpha Male Feeling.”

Benefits of Narrows Labs 4-Andro Xtreme

  • Better power and strength
  • Faster recovery time
  • Enhanced libido
  • Stacking 4-Andro for Experienced Users

You may stack Narrows Labs 4-Andro with almost any compound or natural anabolic without worrying about any unwanted side effects, but it’s most ideally paired with 1-Andro and Epi-Andro (dry compounds) as these do an excellent job in minimizing or avoiding extra water retention.


This is a legal prohormone that bodybuilders can incorporate into their workout. All supplements with this compound can be found in most health stores and no legal implications come with using the compound. That is especially promising in the landscape of bodybuilding today.

Possible Side Effects of 4-Andro

Narrows Labs 4-Andro has little to no side effects. You may experience a minor estrogen conversion, muscle cramps, high blood pressure, aggression and in some rare cases gynecomastia (gyno).
