Comparison
Lion's Mane vs Testosterone
Side-by-side of Lion's Mane and Testosterone. Every row below is pulled from the compound schema and will update as our data grows. For deeper reads, follow through to each compound page.
Lion's Mane
Lion's mane mushroom (Hericium erinaceus) supplement profile: hericenones and erinacines stimulate NGF in vitro. Human cognition trials are small.
Testosterone
Testosterone replacement therapy for hypogonadism: TRAVERSE 2023 cardiovascular data, cypionate dosing, body composition gains, Schedule III status.
Effects at a glance
Lion's Mane
- •Edible medicinal mushroom containing NGF-stimulating hericenones and erinacines
- •Mori 2009 trial (n=30) in mild cognitive impairment showed cognitive improvement at 3 g/day for 16 weeks, reversing 4 weeks after discontinuation
- •Saitsu 2019 (n=31) in older adults reported MoCA improvements at 3.2 g/day over 12 weeks
- •Multiple small mood trials suggest reduced anxiety and depression scores at 1 to 4 g/day extract
- •Mechanistic case rests on NGF stimulation and remyelination support; in vivo human NGF measurement is absent
- •Product quality varies substantially; mycelium-on-grain products can be over 50% grain by weight
Testosterone
- •Primary androgen; FDA approved for hypogonadism with confirmed deficiency and symptoms
- •Testosterone Trials (2016) showed sexual function and bone density improvements in older hypogonadal men
- •TRAVERSE 2023 (n=5,246) found non-inferiority on MACE versus placebo, with higher AF and PE rates
- •Schedule III controlled substance in US; WADA banned in sport
- •Aromatizes to estradiol; converts to DHT via 5-alpha reductase; both metabolites matter clinically
- •Erythrocytosis (HCT above 54%) affects 5 to 25% of users and is the most common dose-limiting effect

Safety profile
Lion's Mane
Common side effects
- mild GI upset
- occasional skin rash
- contact dermatitis (rare)
Contraindications
- mushroom allergy
Interactions
- anticoagulants: theoretical antiplatelet effect, no documented clinical events(minor)
Testosterone
Common side effects
- erythrocytosis
- acne
- oily skin
- fluid retention
- increased body hair
- fertility suppression
- injection-site reactions
Contraindications
- active prostate cancer
- active breast cancer
- untreated severe sleep apnea

- polycythemia at baseline
Interactions
- warfarin: may potentiate anticoagulant effect; monitor INR(moderate)
- insulin: may improve insulin sensitivity; monitor glucose in diabetics(moderate)
- 5-alpha reductase inhibitors (finasteride): blocks DHT conversion; reduces some androgen effects(moderate)
- aromatase inhibitors (anastrozole): lowers estradiol; risk of over-suppression(moderate)
Which Should You Take?
Lion's Mane comes out ahead for most readers on the criteria we weight: 3 catalogued goals, OTC dietary supplement, oral dosing, with a Tier-B outcome catalogued. Testosterone is the right call when one of the conditionals below applies.
- → If your priority is focus or working memory, pick Lion's Mane.
- → If your priority is nerve health, pick Lion's Mane.
- → If your priority is hormonal optimization, pick Testosterone.
- → If your priority is sexual function, pick Testosterone.
Edge case: If you want to avoid controlled substance, Lion's Mane is the more accessible choice.
Default choice: Lion's Mane. Lower friction to source, and broader goal coverage. Reach for Testosterone only if your priority sits squarely in the goals it owns above.
