What It Converts Into
4-Andro converts into testosterone itself.
This makes it the most “traditional” prohormone in terms of hormonal outcome.
How It Works
After conversion, testosterone can:
- Bind androgen receptors
- Convert to DHT
- Aromatize into estrogen
This creates a more complete hormonal environment compared to dry compounds like 1-Andro.
Commonly Reported Effects
- Strength gains
- Muscle mass increases
- Improved pumps
- Increased libido and sense of well-being
Side Effects & Tradeoffs
- Estrogen conversion (water retention possible)
- Suppression of natural testosterone
- Blood pressure changes in some users
- Requires estrogen awareness, not ignorance
Bottom Line
4-Andro is often used as a base compound because it supports androgen levels broadly. It feels more “normal” hormonally than dry compounds but carries estrogen management considerations.
I will be adding a prohormone category to the source list soon
