Example: roids. Used appropriately, they can help improve your body.
Correction: they can improve aspects of your body, at a very, very steep cost. Pretty much all oral anabolic steroids are C17α-alkylated, and they’re hepatotoxic (i.e., cause liver damage). All steroids will fuck up your lipid profile to one degree or another, and all of them can cause heart disease, specifically hypertrophic cardiomyopathy. While most AASs will increase red blood cell count, Boldenone in particular will sharply increase RBC production, which in turn increases blood pressure and can cause strokes. All of them will shut down the hypothalmus-pituitary-testicular axis (HPTA) feedback loop in men, leading to testicular atrophy. Most AASs will cause hair loss in men that are sensitive to DHT. AASs can fuck up your hormones enough that men can start lactating (!!!). High doses of testosterone can cause gynecomastia, because testosterone aromatizes into estradiol. In women, all AAS will cause some degree of virilization.
There are not very many IFBB pros that make it to 80; if you want your candle to burn brightly, it’s going to burn out fast.
It really depends on where you bury the body. Once you get out of developed areas, it gets very hard to track things down. Take this example; she was missing for two years, and her body was found in a tent, in a sleeping bag, just two miles off the Appalachian trail, which is one of the busiest hiking trails in the US. If someone was actually buried out there, the odds that they’d ever be found are very, very poor.
Admittedly, carrying a body off trails through fairly dense forests ain’t gonna be easy. If you were going to do it, I’d say start by getting an old car with no GPS, get some paper maps, make sure that you leave all of your electronics at home so that there’s no electronic trail of where you’ve been (especially your cell phone!), and only use cash for gas, etc. while you’re driving to your body dump site. Assuming that the body isn’t recovered for at least a year, you’re likely in the clear.
