Testosterone — Nutrient Associations & Health Patterns
Also known as: Testosterone cypionate / enanthate / gel / patch (Androgel, Testim, Depo-Testosterone, Natesto)
Drug Class: Androgen / Hormone replacement therapy
Bioidentical androgen used for male hypogonadism (low testosterone), gender-affirming hormone therapy, and off-label use in perimenopausal women at low doses. Available as injections (cypionate or enanthate), transdermal gels (Androgel), patches, nasal gel, and pellets. Requires ongoing monitoring of hematocrit, PSA, estradiol levels, and cardiovascular markers. Aromatizes to estradiol — estrogen management is part of TRT for many men.

Common Side Effects of Testosterone
- Elevated hematocrit (polycythemia — clot risk — requires blood donation or dose reduction)
- Acne
- Hair loss / male-pattern baldness acceleration (DHT-mediated)
- Testicular atrophy (from suppression of endogenous production)
- Infertility (suppresses LH/FSH — sperm production halted)
- Elevated estradiol (gynecomastia, mood swings, water retention — from aromatization)
- Sleep apnea worsening
- Injection site reactions (intramuscular) or skin irritation (gel)
Key Drug Interactions — Testosterone
Testosterone has 9 documented drug-drug interactions in WePattern's Pattern Health Intelligence database. Key interactions include:
- Warfarin (testosterone increases anticoagulation — INR monitoring required)
- Insulin and antidiabetics (testosterone improves insulin sensitivity — may need dose reduction)
- Corticosteroids (additive fluid retention and edema)
- Blood pressure medications (testosterone can raise blood pressure — monitor)
- Finasteride (blocks DHT conversion — used intentionally to reduce hair loss on TRT)
- Aromatase inhibitors — anastrozole, exemestane (used to manage estradiol elevation from aromatization)
