Half-Life Terminal half-life 44.7 hours in humans, measured in a first-in-human phase 1 study in postmenopausal women with metastatic breast cancer (PMID: 34565686) ## Administration Routes Oral Dosage Calculator Calculate exact dosing for RAD-140 (Testolone). https://www.bodyhackguide.co/tools/dosage Dosing data for RAD-140 (Testolone) is being researched. Check the compound page (https://www.bodyhackguide.co/compound/rad-140) for the latest information. ## Side Effects & Safety In the phase 1 study of 22 patients, treatment-emergent adverse events included raised aspartate aminotransferase in 59.1 percent, raised alanine aminotransferase in 45.5 percent, raised total bilirubin in 27.3 percent, and vomiting, dehydration, reduced appetite and weight loss in 27.3 percent each; grade 3 or 4 events occurred in 16 of 22 patients (PMID: 34565686). Published case reports outside trials describe biopsy-confirmed cholestatic liver injury with prolonged jaundice after RAD-140 use (PMID: 36561105, PMID: 36945289, PMID: 39328701, PMID: 36978171, PMID: 38444893), one case of bile cast nephropathy and kidney injury needing plasmapheresis in a man who had used three different SARMs (PMID: 37501938), and cardiac events including acute myocarditis (PMID: 35233331), myopericarditis in an adolescent (PMID: 39157568) and heart failure (PMID: 38864168). In female mice, long-term RAD140 raised frailty and mortality risk (PMID: 37758180). Contraindications Mechanism-based: contraindicated in pregnancy, since androgen receptor agonists can virilize a female fetus, and in men with known or suspected prostate cancer. Pre-existing liver disease or raised transaminases is both mechanism-based and case-report-based, given how frequently transaminase and bilirubin rises appeared in the phase 1 trial and in published liver injury reports (PMID: 34565686, PMID: 36945289). Cardiac case reports, including one in a 16-year-old, are a reason to avoid it in anyone with known cardiac disease (PMID: 39157568, PMID: 38864168). Prohibited in tested sport at all times (PMID: 28137616).
