Thailand is a popular location to buy performance enhancing drugs (PED) due to its availability and low cost. Pharmacies in Bangkok, Pattaya and Phuket sell a nice range of steroids, HGH and peptides over the counter without a prescription. However, buying anabolic steroids and growth hormones can be tricky as pharmacies have become increasingly cautious during the past decade and keep less or no stock on premises. In the same period, several manufacturers of performance enhancing drugs have upheld strong reputations for producing quality sought after products.
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.
