About 4-AD

With so many prohormones on the market claiming to produce unthinkable results, its hard to know which of them actually work. Advanced Muscle Science made sure that you’re getting only the best with their products, which is why we swear that 4-AD will give you the crazy explosive size and strength results you crave. AMS loaded 4-AD with a potent dose of 4-Andro, the mass building prohormone that gets converted into natural testosterone via a two-step conversion process. With 4-AD, you will experience heightened aggression and superhuman endurance so that you can push yourself through even the toughest of workouts. The anti-catabolic effects of 4-AD ensure that you are building lean muscle and burning body fat at optimal levels, giving you crazy lean mass gains.

What’s more, Advanced Muscle Science uses their revolutionary SEDDS delivery system to ensure that you are getting the maximum benefits from each tablet of 4-AD. This top-of-the-line technology ensures that you are getting maximum absorption of ingredients, which in turn makes each dose of 4-AD more effective. SEDDS protects the ingredients in Arom-X from the harsh environment of your body’s digestive system to allow for optimal delivery of these powerful ingredients into your bloodstream. Add 4-AD from AMS to your cart today and let the gains begin!


  • explosive size and strength gains
  • boosted aggression
  • increased endurance
  • non-methylated and non-liver toxic


All cycles of 4-AD should be followed up with Post Cycle Therapy in order to return hormone levels to normal. We recommend adding Advanced Muscle Science's Arom-X PCT to your cart to cover all of your post-cycle needs!

For on-cycle support, we recommend stacking 4-AD with IronMag Labs Advanced Cycle Support to ensure complete liver protection and support overall organ health both during and after your cycle.
