19-Nor Prohormone Guide: 19-Nor-DHEA & Top Product Choices

What is 19-Nor Andro?

19-Nor Andro is a popular andro supplement commonly used by individuals looking to build lean muscle mass and increase overall strength. It is known for increasing testosterone levels in the body, which plays a key role in muscle growth, endurance, and recovery.

Many users choose 19-Nor Andro because it is associated with:

  • Increased lean muscle mass
  • Improved strength and endurance
  • A leaner, more defined look

As a result of it's strength and effectiveness, 19-Nor Andro is generally considered more suitable for intermediate to advanced users rather than beginners. 

What is 19-Nor-DHEA?

19-Nor-DHEA is a compound that acts as a precursor to nandrolone. It is also known by several other names, including:

  • 19-Norandrostenedione
  • Estrenolone
  • Norandrostenolone
  • Nortestosterone

This compound is six times more anabolic than testosterone, which is why it has become popular among experienced athletes and bodybuilders.

Nandrolone vs. Testosterone: Why is 19-Nor Different?

Nandrolone is very similar to testosterone in structure. The main difference is that 19-Nor Andro is missing the 19th carbon atom and certain hydrogen atoms. Aside from this change, the compounds are otherwise identical. 

The difference is often highlighted because it is associated with fewer side effects, particularty related to prostate and sexual issues. As a result, users seek 19-Nor Andro to experience anabolic effects linked to increased testosterone without some of the commonly discussed negative effects.

Benefits of 19-Nor

Athletes often turn to 19-Nor DHEA during bulking or strength-focused phases, where consistent training performance and gradual muscle accumulation are the priority. Users commonly report:

  • Improved workout recovery
  • Increased training volume tolerance
  • Steady strength gains over the course of a cycle.

Due to their nature, these compounds are frequently stacked with testosterone-supporting prohormones to help maintain balance.

19-Nor Andro vs. 1-Andro

While both are popular andro supplements, they are typically chosen for different goals.

1-Andro is often used during cutting phases and is considered more beginner-friendly. Many users choose 1-Andro when the primary focus is fat loss and lean muscle preservation.

19-Nor Andro, on the other hand, can be used for both cutting and mass-building, depending on diet and training. As a result of its strength, it is recommended for intermediate to advanced users. 

Cycling, Dosing & Time Off

19-Nor Andro is commonly cycled for up to eight weeks, followed by a post-cycle therapy (PCT) and a period of time off before starting another cycle.

A commonly followed example cycle includes:

  • Weeks 1-8: Decabolin - 2 capsules per day (one in the morning and one in the evening)
  • Weeks 8-12: Post-Cycle Therapy (PCT) - 2 capsules per day
  • Weeks 12-18: Off cycle

Post-cycle therapy is recommended to help the body to return to normal hormone levels. A great PCT option is Blackstone Labs PCT-V. After completing PCT, users typically take 4-8 weeks off before beginning a new cycle.
