Esters refer to different types of compounds and chemicals that manufacturers use subtly change their products. Using esters in a synthetic steroid can help the steroid better bond to receptors. This helps the steroid remain in the body and continue producing effects for more time. Though esters can take different forms depending on the product, the manufacturers of steroids often use some combination of oils or fats. When originally used in veterinary offices, Tren Acetate contained a high level of natural oils. Thoroughly mixing the steroid with the oil was the first step associated with using it. While the newer products still contain some fats, users will find that these oils don’t lead to weight gain and that they no longer need to mix the liquid.
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.
