Many athletes, ball players, fighters, and any athlete who could benefit from the therapeutic relief often supplement with Deca Durabolin. Such individuals commonly have no desire to build any new lean muscle mass, but the relief alone is invaluable. Further, such relief can be obtained by a very low dose. A slightly higher dose will provide relief, greatly enhance overall recovery, and enhance muscular endurance. When it comes to performance enhancement, most athletes will find this steroid is hard to beat. More importantly, the relief effects of Deca Durabolin are not masking or false; this anabolic steroid shares nothing in common with over the counter painkillers or prescription painkillers like opiates. Such painkillers only mask the pain, whereas Deca Durabolin can actually heal the body.
All anabolic steroids have a tendency to reduce HDL (good) cholesterol and increase LDL (bad) cholesterol. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable) type of steroid (aromatizable or non-aromatizable) and level of resistance to hepatic metabolism. With regards to nandrolone at a dose of 600mg per week over 10 weeks demonstrated 26% reduction in HDL cholesterol levels. This suppression is slightly greater than an equal dose of testosterone over an equal period. In other words it shows a slightly more negative impact on HDL/LDL ratio with nandrolone than with testosterone cypionate. It’s always recommended to accompany the use of this product with a low saturated fat diet and a cardiovascular exercise program.
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.
