In some countries, such as Mexico, there are very few laws or restrictions in place when it comes to where to buy steroids. It’s possible to get them in pharmacies without a prescription, and some even obtain them from veterinarians. Keep in mind that while this practice is considered legal in these countries, there are very strict laws that prevent you from carrying steroids across international borders. These penalties often include jailtime and large fines, and they can have lifelong impacts. If you choose to purchase anabolic steroids for sale in other countries, do so safely.
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.
