Transdermal patches (adhesive patches placed on the skin) may also be used to deliver a steady dose through the skin and into the bloodstream. Testosterone-containing creams and gels that are applied daily to the skin are also available, but absorption is inefficient (roughly 10%, varying between individuals) and these treatments tend to be more expensive. Individuals who are especially physically active and/or bathe often may not be good candidates, since the medication can be washed off and may take up to six hours to be fully absorbed. There is also the risk that an intimate partner or child may come in contact with the application site and inadvertently dose himself or herself; children and women are highly sensitive to testosterone and can suffer unintended masculinization and health effects, even from small doses. Injection is the most common method used by individuals administering AAS for non-medical purposes. 
Organon Sustanon is a legal pharmacy drug that is produced in Pakistan. It is one of the commonly known brands of Sustanon in the world. There are 4 different testosterone esters in it, like Testosterone propionate, testosterone phenylpropionate, testosterone isocaproate and testosterone decanoate. It is a pharmacological drug. But it attracts great attention by the bodybuilders. When it is injected to the body once every 5 days and it is used in the period of 8-10-12 weeks, it gives effective results. Because it has short ester testosterone derivatives, after 4-5 days from the first injection you will feel a strong increase in your weight trainings. This is one of the biggest indications of original Sustanon. However it accumaletes a significant amount water in the body. So, water retention occurs under the skin. Because it has 4 different testosterone esters, during the injection it may cause the pain on the hip. And also there is a risk of gynecomastia, we recommend that you must use PCT products like Nolvadex, Proviron, Arimidex during a cycle. While using Sustanon, if you eat protein and carbohydrate foods and pay attention to your alimentation and your sleep, you may gain circa 6-7 kg muscle mass, but this is linked to the personal conditions.
