Mucuna Pruriens (The Dopamine Bean)
Also Known As: Velvet Bean, Cowhage, L-Dopa Source
Compound Type: Adaptogen / Neurotransmitter Support / HGH Booster
Mucuna Pruriens is a tropical legume that has been used in Ayurvedic medicine for thousands of years. It is the richest natural source of L-Dopa, the direct precursor to the neurotransmitter Dopamine.
For Penis Enlargement, Mucuna plays a specific and vital role: it crushes the “Refractory Period.” By boosting Dopamine, it inhibits Prolactin—the hormone responsible for making you lose your erection immediately after ejaculation. This allows for faster recovery between rounds and higher training intensity.
How Does Mucuna Help Size?
It optimizes the hormonal environment for growth by boosting HGH and lowering the “anti-sex” hormone, Prolactin.
The Science: Dopamine vs. Prolactin
1. The Prolactin Inhibitor:
Prolactin is the hormone released after orgasm that causes sexual satisfaction and flaccidity. High Prolactin kills libido. L-Dopa (from Mucuna) increases Dopamine, which directly suppresses Prolactin levels. This keeps your system “primed” for sexual activity and training.
2. HGH Secretagogue:
L-Dopa is a known growth hormone secretagogue. It stimulates the pituitary gland to release Human Growth Hormone (HGH), which is essential for cell repair and tissue regeneration after intense stretching exercises.
3. Testosterone Support:
A study on infertile men showed that Mucuna supplementation significantly improved Testosterone levels and sperm count by reducing cortisol (stress) and oxidative damage.
Do not take Mucuna every day forever.
Your body can build a tolerance to L-Dopa. We recommend a “5 Days On, 2 Days Off” cycle to keep your dopamine receptors sensitive and effective.
✔ The Verdict: REFRACTORY KILLER
4/5 Stars. This is the ultimate supplement for “rounds.” If you want to train (jelq) immediately after sex, or if you want to have sex multiple times a night, Mucuna is the tool to make that biologically possible.

Safety Profile & Side Effects
- Nausea: L-Dopa can cause nausea if taken on an empty stomach. Always start with a low dose.
- Vivid Dreams: Increased dopamine often leads to very intense, realistic dreams.
- MAOIs: NEVER combine L-Dopa with MAO Inhibitors (antidepressants). This can cause a dangerous spike in blood pressure.
- B6: Vitamin B6 helps convert L-Dopa to Dopamine peripherally. Some prefer taking them together, others separate.
