You’ll find many people who disagree with this train of thought simply because they have used it themselves, but you need to ask yourself A: if this person is at a professional level, and B: how well they place in their competitions, plus, consider their physicality against yours; it’s possible that their frame could “absorb” the effects of drol, but it’s unlikely that % of the gym going world could “wear” its effects so well. In short, unless you’re at Mr Olympia level with a ridiculous level of fat free mass and a super low body fat percentage – you’re incredibly unlikely to enhance your cut using anadrol.
Testosterone can be administered parenterally , but it has more irregular prolonged absorption time and greater activity in muscle in enanthate , undecanoate , or cypionate ester form. These derivatives are hydrolyzed to release free testosterone at the site of injection; absorption rate (and thus injection schedule) varies among different esters, but medical injections are normally done anywhere between semi-weekly to once every 12 weeks. A more frequent schedule may be desirable in order to maintain a more constant level of hormone in the system.  Injectable steroids are typically administered into the muscle, not into the vein, to avoid sudden changes in the amount of the drug in the bloodstream. In addition, because estered testosterone is dissolved in oil, intravenous injection has the potential to cause a dangerous embolism (clot) in the bloodstream.
