I get 2, 4 and 5 and I’m completely natural. I have had people accuse me of taking steroids many times and it pissed me off. It gets me to the point where I want to take steroids just so that I can say “Now this is me on steroids fckers!”. Lol. But nah I get a lot of acne outbreaks naturally and I have had many stretch marks as well as abnormally fast muscle gains. I’m a very lean person and when I stop working out I’m capable of drastically going from jacked to skinny as heck. When I start back up again I blow up quick. Another thing I’ve noticed is my pumps are naturally a lot more intense then the average lifter. Like my shoulders blow up like bowling balls and veins and shreds show up all over them along with my arm’s and chest. I’ve had a tone of people accuse me of taking steroids because of these factors. I also had a relative hug me once and say I was jacked and as solid as steal. He said only steroids do that. (He took steroids in the past) But it is to my understanding that muscle is solid… or at least a lot more solid than fat. At the time I was taking creatine and l-arginine with citrilline malate (which is a precursor to arginine) and a lot of BCAA’s.
Pancuronium remains one of the few muscle relaxants logically and rationally designed from structure-action / effects relationship data. A steroid skeleton was chosen because of its appropriate size and rigidness. Acetylcholine moieties were inserted to increase receptor affinity. Although having many unwanted side-effects, a slow onset of action and recovery rate it was a big success and at the time the most potent neuromuscular drug available. Pancuronium and some other neuromuscular blocking agents block M2-receptors and therefore affect the vagus nerve , leading to hypotension and tachycardia . This muscarinic blocking effect is related to the acetylcholine moiety on the A ring on pancuronium. Making the N atom on the A ring tertiary, the ring loses its acetylcholine moiety, and the resulting compound, vecuronium, has nearly 100 times less affinity to muscarin receptors while maintaining its nicotinic affinity and a similar duration of action. Vecuronium is, therefore, free from cardiovascular effects.  The D ring shows excellent properties validating Beers and Reich's rule with great precision. As a result, vecuronium has the greatest potency and specificity of all mono-quaternary compounds. 
However, the Anavar steroid was discontinued by Searle in 1989, due to the bad press brought on by bodybuilders abusing the drug. It was later reintroduced to the world market as Oxandrin in 1995, but it remains a controlled substance under US law. The current manufacturer of oxandrolone holds all the rights to their medicine, and that’s why it is very rare to find oxandrolone today. It’s still called Anavar by most people, and it’s very hard to buy. Even if you do find Anavar for sale, the law of supply and demand inevitably results in a rather exorbitant price for the steroid.
