There are only a couple sites I’d list that don’t write their own material because almost all of them just post random articles and the worst of them just outright steal posts from people who take the time to actually research and write them. Todd Sepulveda’s site is different . It’s actually very useful. It’s like the Drudge Report of prepper information. Not only does he have a LOT of articles listed on his site, he personally vets each one. If you’re looking for a good article on some topic or a great list of sites to look into, this site is where to start.
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.
