Cabergoline vs Oxandrolone
FDA Approved vs Well Studied
synergistic Mechanism-based · 55% Oxandrolone supports hormonal recovery from suppression caused by Cabergoline. Standard protocol — begin PCT after the suppressive compound has cleared based on its half-life.
Molecular Data
Cabergoline Oxandrolone
Weight 451.60 Da 306.44 Da
Half-life ~63-69 hours ~9-10 hours
Type Ergoline-derived dopamine D2 receptor agonist 17-alpha-alkylated anabolic-androgenic steroid (C19H30O3)
Key Benefits
Cabergoline
01 Potent suppression of prolactin levels, often normalizing them within days
02 Prevents and reverses prolactin-related gynecomastia from 19-nor compounds
03 Restores sexual function impaired by hyperprolactinemia (libido, erectile function, orgasm)
04 Long half-life (63-69 hours) allows convenient twice-weekly dosing
05 Significantly better tolerated than bromocriptine with fewer gastrointestinal side effects
06 Effective at shrinking prolactin-secreting pituitary tumors
07 Low doses required for bodybuilding prolactin management (0.25-0.5mg twice weekly)
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
Side Effects
Cabergoline
Nausea (especially during initial doses; mitigated by taking with food)
Dizziness or lightheadedness
Headache
Nasal congestion or stuffiness
Fatigue or drowsiness
Orthostatic hypotension (feeling faint when standing up quickly)
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 hypersensitivity to cabergoline or any ergot alkaloid
History of cardiac valvular disease or clinically significant valvular regurgitation
History of pulmonary, pericardial, or retroperitoneal fibrotic disorders
Uncontrolled hypertension
Concurrent use of dopamine antagonists (antipsychotics, antiemetics acting on D2 receptors)
Severe hepatic impairment (cabergoline is extensively metabolized by the liver)
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
