Legendary pro wrestler and bodybuilder Ric Draisin, who was widely known as one of Arnold Schwarzenegger’s early training partners, was described as a WFN “ambassador and media partner”. Acclaimed documentary movie maker Chris Bell, who directed documentaries related to anabolic steroids and pharmaceuticals such as “Bigger Stronger Faster” and “Prescription Thugs”, gave a glowing testimonial praising WFN as one of the “top compounding pharmacies in the country” as “100% legal”; Bell spoke highly of “Dr. Rodriguez” for providing him with steroids and steroid advice.

Metabolic effects occurring during anabolic steroid therapy in immobilized patients or those with metastatic breast disease have included osteolytic-induced hypercalcemia. Anabolic steroids affect electrolyte balance, nitrogen retention, and urinary calcium excretion. Edema, with and without congestive heart failure, has occurred. Decreased glucose tolerance requiring adjustments in hyperglycemic control has been noted in diabetic patients. Significant increases in low density lipoproteins (LDL) and decreases in high density lipoproteins (HDL) have occurred. [ Ref ]

Rivaroxaban is administered orally. Plasma protein binding of rivaroxaban in human plasma is approximately 92% to 95%; albumin is the main binding component. The volume of distribution at steady state is approximately 50 L in heathy subjects. Oxidative degradation catalyzed by CYP3A4/5 and CYP2J2 and hydrolysis are the major sites of biotransformation. Unchanged rivaroxaban was the predominant moiety in plasma with no major or active circulating metabolites. In a Phase I study, after the administration of [14C]-rivaroxaban, 36% was recovered in the urine as unchanged drug and 7% was recovered in the feces as unchanged drug. Unchanged drug is excreted into urine, mainly via active tubular secretion and to a lesser extent via glomerular filtration (approximate 5:1 ratio). Rivaroxaban is a substrate of the efflux transporter proteins P-glycoprotein and ABCG2 (also abbreviated BCRP). Rivaroxaban’s affinity for influx transporter proteins is unknown. Rivaroxaban is a low-clearance drug, with a systemic clearance of approximately 10 L/hour. The terminal elimination half-life of rivaroxaban is 5 to 9 hours in healthy patients aged 20 to 45 years.
 
The anticoagulant effect of rivaroxaban cannot be monitored with standard laboratory testing or be readily reversed. Dose-dependent inhibition of factor Xa activity was observed in humans and the Neoplastin prothrombin time (PT), activated partial thromboplastin time (aPTT), and HepTest are prolonged dose-dependently. Anti-factor Xa activity is also influenced by rivaroxaban. No data exist on the use of the International Normalized Ratio (INR). The predictive value of these coagulation parameters for bleeding risk or efficacy has not been established.
 
Affected cytochrome P450 isoenzymes and drug transporters: CYP3A4, CYP3A5, CYP2J2, P-glycoprotein (P-gp), ABCG2
Rivaroxaban is a substrate of CYP3A4/5, CYP2J2, and the P-gp and ATP-binding cassette G2 (ABCG2) transporters. Inhibitors and inducers of these CYP450 enzymes or transporters may result in changes in rivaroxaban exposure. Avoid use of rivaroxaban with combined P-gp and strong CYP3A4 inhibitors, which cause significant increases in rivaroxaban exposure that may increase bleeding risk. In vitro studies indicate that rivaroxaban neither inhibits the major cytochrome P450 enzymes CYP1A2, 2C8, 2C9, 2C19, 2D6, 2J2, and 3A4 nor induces CYP1A2, 2B6, 2C19, or 3A4. In vitro data also indicates a low rivaroxaban inhibitory potential for P-glycoprotein and ABCG2 transporters. However, no significant pharmacokinetic interactions were observed in studies comparing concomitant rivaroxaban 20 mg and mg single dose of midazolam (substrate of CYP3A4), mg once-daily dose of digoxin (substrate of P-gp), or 20 mg once daily dose of atorvastatin (substrate of CYP3A4 and P-gp) in healthy volunteers.
