Ecdysterone vs Oxandrolone
Moderate Research vs Well Studied
avoid Mechanism-based · 64% Both Ecdysterone and Oxandrolone carry hepatotoxic risk. Combining hepatotoxic compounds significantly increases liver damage potential. If unavoidable, include liver support (TUDCA/NAC) and monitor ALT/AST frequently.
Molecular Data
Ecdysterone Oxandrolone
Weight 480.64 Da 306.44 Da
Half-life ~4-9 hours ~9-10 hours
Type Ecdysteroid (C27H44O7) 17-alpha-alkylated anabolic-androgenic steroid (C19H30O3)
Key Benefits
Ecdysterone
01 Activation of muscle protein synthesis through ERbeta/PI3K/Akt/mTOR signaling without androgen receptor binding
02 Statistically significant increases in lean muscle mass demonstrated in a controlled human trial in trained subjects
03 No hormonal suppression -- does not affect testosterone, LH, or FSH levels, eliminating the need for post-cycle therapy
04 No androgenic side effects (no hair loss, acne, prostate issues, or virilization in women)
05 No hepatotoxicity, unlike oral anabolic steroids that undergo 17-alpha alkylation
06 Naturally occurring in common foods (spinach, quinoa), with a long history of safe dietary exposure
07 Compatible with other performance compounds due to its non-hormonal mechanism
08 Available as a dietary supplement without prescription in most jurisdictions
Oxandrolone
01 Promotes lean muscle mass gains with minimal water retention
02 Supports recovery of lost body weight following surgery, trauma, or chronic illness
03 Reduces bone pain associated with osteoporosis and improves bone mineral density
04 Does not aromatize to estrogen, avoiding estrogen-related side effects
05 Well-studied safety profile in women, children, and burn patients
06 Enhances nitrogen retention and protein synthesis during caloric deficit
07 Attenuates glucocorticoid-induced catabolism in post-surgical and burn patients
08 Lower androgenic potency compared to most oral anabolic steroids
Dosing Protocols
Ecdysterone
500-1000 mg/day (oral) or 50-100 mg/day (injectable) / 1-2x daily
Enhanced Anabolic Effect / Higher Bioavailability 50-100 mg/day Once daily
Oxandrolone
20-50 mg/day (male), 5-20 mg/day (female) / Split into 2 doses daily (morning and evening)
Side Effects
Ecdysterone
Mild gastrointestinal discomfort (nausea, bloating, or stomach upset) with oral doses, particularly at higher dosages taken without food
Injection site pain, redness, or mild swelling with injectable administration
Oxandrolone
HDL cholesterol suppression (dose-dependent, most significant lipid effect)
LDL cholesterol elevation
Mild hepatic stress (elevated liver enzymes ALT/AST)
Suppression of endogenous testosterone production
Mild headaches
Nausea or gastrointestinal discomfort
Changes in libido (increase or decrease depending on hormonal context)
Oily skin and mild acne
Contraindications
Known allergy to ecdysteroids or spinach-derived compounds
Pregnancy and breastfeeding (insufficient safety data)
Individuals with estrogen-sensitive conditions should consult a physician, though ERbeta activation is generally considered protective rather than proliferative
Known or suspected prostate cancer
Breast cancer in males
Breast cancer with hypercalcemia in females
Pregnancy (Category X - known to cause fetal harm)
Nephrosis or nephrotic phase of nephritis
Hypercalcemia
Severe hepatic dysfunction or active liver disease
Hypersensitivity to oxandrolone or any formulation component
