Tribolin A veterinary anabolic steroid blend
Tribolin A is a veterinary anabolic steroid blend that combines two powerful compounds:
- Nandrolone (typically as nandrolone phenylpropionate)
- Methandriol dipropionate (an androgenic steroid with mild estrogenic effects)
This blend was originally used for veterinary purposes, particularly in livestock (like cattle and horses) to promote muscle growth, weight gain, and recovery. However, over the years, it has gained attention in the bodybuilding and performance-enhancing community due to its unique anabolic profile.
Active Compounds Explained
1. Nandrolone Phenylpropionate (NPP)
- A fast-acting version of Deca-Durabolin
- Known for promoting lean muscle growth, joint relief, and low androgenic side effects
- Low estrogen conversion, making it popular during bulking or recovery phases
2. Methandriol Dipropionate (MADP)
- A less common steroid, often used to enhance the effectiveness of other steroids
- Adds mild androgenic and estrogenic balance
- Thought to improve anabolic synergy when blended with nandrolone or testosterone
Why Is It Blended?
Tribolin A aims to:
- Improve nitrogen retention and protein synthesis
- Offer a balanced anabolic-androgenic effect
- Deliver faster results than long-acting nandrolone alone
- Create a less suppressive alternative compared to harsher stacks
Some users believe methandriol acts as a kind of “potentiator” by making the body more responsive to the nandrolone.
Reported Benefits (Anecdotal)
- Moderate but steady lean muscle gains
- Reduced joint pain and improved recovery
- Enhanced synergy in multi-compound steroid stacks
- Less water retention than testosterone-based cycles
Risks and Side Effects
- Testosterone suppression (especially from the nandrolone)
- Possible progesterone-related side effects like bloating or libido issues
- Androgenic effects (acne, hair loss) depending on dosage and sensitivity
- Estrogenic side effects (from methandriol), although typically mild
- As a veterinary drug, human use is not recommended or medically approved
Legality and Availability
- Not approved for human medical use
- May still be found on underground or veterinary-grade markets
- Banned in competitive sports and flagged by all major anti-doping agencies
Final Thoughts
Tribolin A is a niche compound in the anabolic steroid world. While it’s not widely used or commercially produced for human use, some advanced users seek it out for its unique combination of lean gains and recovery support. However, its veterinary origin, limited research, and unknown human safety profile make it a risky choice without strict medical oversight.
