Butea superba to Improve Testosterone

Created on 08/10/2026 – Quick Reference based on Evidence Review created using AI4L / Grok 4 – Audit

Butea superba is a traditional Thai root herb for male vitality. Human data show improved erectile scores without a clear testosterone rise. Commercial products carry adulteration risk. Evidence does not establish it as a reliable testosterone-raising approach. Identity testing, conservative dosing, and hormone and liver monitoring frame any cautious experiment. (Full Review)

Protocol

Dose
~500–1,000 mg/day
Dried tuber powder in 250 mg capsules; up to four capsules daily after a short run-in
Form & quality
Single-ingredient root
Third-party COA for identity and undeclared PDE5 drugs (sildenafil, tadalafil, analogues)
Trial frame
8–12 weeks
Time-limited course with baseline and follow-up labs; studied human use about three months for ED
Time to effect
Erectile function scores
Up to ~3 months
Assessed over a three-month course in the main human trial
Acute erectile intent
1–2 hours
Pre-activity dosing used in a commercial-product study
Hormone lab change
Weeks to months
If any change occurs; best human data show no significant mean testosterone shift

Benefits

Contraindications
  • Nitrates and nitric-oxide donors (nitroglycerin, isosorbide mononitrate/dinitrate, amyl nitrite; absolute if product is PDE5-adulterated)
  • Women who are pregnant, breastfeeding, or seeking fertility care
  • Active hormone-sensitive malignancy
  • Children and adolescents
  • Unwillingness to obtain identity/adulteration testing for sexual-enhancement supplements
    •
Key Interactions
  • Prescription PDE5 inhibitors (sildenafil, tadalafil, vardenafil, avanafil)
  • Antihypertensives (e.g., amlodipine, lisinopril, losartan)
  • Hormone therapies (testosterone replacement, anti-androgens, aromatase inhibitors, estrogen therapies)
  • Other multi-herb sexual-enhancer products marketed as testosterone supports (Tribulus, tongkat ali, yohimbine, high-dose fenugreek, etc.)
  • Over-the-counter antiplatelets and nonsteroidal anti-inflammatory drugs (NSAIDs; aspirin, ibuprofen, naproxen)
  • Anticoagulants / antiplatelets (warfarin, aspirin, clopidogrel)
    •

Risk & Side Effects

  • High:
  • Medium: Product adulteration with undeclared PDE5 inhibitors
    •
  • Low: High-dose androgen suppression and liver enzyme elevation; genotoxicity signal at extreme doses; case-level hyperandrogenemia
    •
  • Speculative: Estrogenic / anti-estrogenic tissue effects and hormone-sensitive conditions; unknown long-term human safety
    •

Monitoring

Marker Target Why
Total testosterone (morning) Often ~500–900+ ng/dL in optimization-oriented practice (lab-specific) Primary goal marker for this review
Free testosterone Mid–upper functional band (method-specific) Bioavailable androgen fraction
SHBG Roughly mid-reference (lab-specific) Interprets free vs total T
DHT Within lab reference Detects the hyperandrogenemia pattern in the case report
LH Mid-reference Distinguishes primary vs secondary patterns
FSH Mid-reference Sperm-line and gonadotropin context
Estradiol (sensitive) Men: often ~20–30 pg/mL functional discussion range Aromatization and symptom balance
AST / ALT / ALP Within lab reference High-dose rat hepatotoxicity signal
CBC Within reference High-dose rat neutrophil/eosinophil shifts
Fasting glucose / lipids Per metabolic goals General cardiometabolic context for ED

Cadence: Baseline before first dose; approximately 4 weeks and again at 8–12 weeks, or at symptom change

Qualitative Assessment

  • Morning energy and motivation
  • Libido and sexual confidence
  • Erectile rigidity and consistency (if ED is present)
  • Sleep quality and recovery from training
  • Androgenic skin or hair changes (acne, accelerated scalp hair loss) that might track DHT
  • Headache, flushing, or blood-pressure symptoms that could signal PDE5-like adulteration
