Lets look at an example. Your doctor has you on testosterone replacement. You are 45 and have had low test since the age of 40. This condition is very very common. Low testosterone has all sorts of negative health repurcussions. Normal testosterone levels are between 300 and 1100 ng. You want to be at around 1100.. Your doctor wants you around 700-800. To do so he prescribes exogenous test at 150 mgs/week. That amount puts your total test at 760 ng, and your fee test around 10. Adding Masteron increases your free test to 19, Your total test is the same, but your free test, the test you actually use, is much more.
“Synthetic oxytocin is sold as proprietary medication under the trade names Pitocin and Syntocinon, and as generic oxytocin. Oxytocin is destroyed in the gastrointestinal tract, so must be administered by injection or as nasal spray. It has a half-life of typically about three minutes in the blood, and given intravenously does not enter the brain in significant quantities – it is excluded from the brain by the blood–brain barrier. Evidence in rhesus macaques indicates oxytocin by nasal spray does enter the brain. Oxytocin nasal sprays have been used to stimulate breastfeeding, but the efficacy of this approach is doubtful.
Injected oxytocin analogues are used for labor induction and to support labor in case of difficult parturition. It has largely replaced ergometrine as the principal agent to increase uterine tone in acute postpartum hemorrhage. Oxytocin is also used in veterinary medicine to facilitate birth and to stimulate milk release. The tocolytic agent atosiban (Tractocile) acts as an antagonist of oxytocin receptors; this drug is registered in many countries to suppress premature labor between 24 and 33 weeks of gestation. It has fewer side effects than drugs previously used for this purpose (ritodrine, salbutamol, and terbutaline).
The trust-inducing property of oxytocin might help those who suffer from social anxieties and mood disorders, but with the potential for abuse with confidence tricks and military applications.”
For the off-season athlete there is no anabolic steroid more important or beneficial than testosterone. High levels of testosterone will promote significant increases in lean muscle mass and strength. This is assuming that the individual is consuming adequate calories. Compounds like Testosterone Propionate are not magical, you will still need to feed your body enough calories. During an off-season period of growth, this means total caloric intake will need to be slightly above maintenance. This will, unfortunately, promote body fat gain. However, the key to a successful off-season is gaining lean tissue while minimizing body fat gain to the fullest extent possible. By supplementing with Testosterone Propionate you will be able to achieve this more efficiently. High testosterone levels will promote a stronger metabolic rate. This is not a license to eat like there’s no end in sight, but you should be able to make better use of your calories.
