It can occur when someone drinks toad soup, eats toad meat or toad eggs, or swallows live toads on a bet. It can also happen when someone deliberately takes commercial substances made with toad toxins. These go under names including  "Kyushin", "Chan Su" (marketed as a painkiller, topical anesthetic or cardiac treatment), "Rockhard" and "Love Stone" (marketed as aphrodisiacs). "Chan Su" (literally "toad venom") is often adulterated with standard painkillers, such as paracetamol, promethazine and diclofenac. It may be ingested or injected. References

Testosterone undecanoate, sold under the brand names Andriol and Aveed among others, is an androgen and anabolic steroid (AAS) medication that is used mainly in the treatment of low testosterone levels in men, including hormone therapy for transgender men. It is taken by mouth or given by injection into muscle.Side effects of testosterone undecanoate include symptoms of masculinization like acne, increased hair growth, voice changes, hypertension, elevated liver enzymes, hypertriglyceridemia, and increased sexual desire. The drug is a prodrug of testosterone, the biological ligand of the androgen receptor (AR) and hence is an androgen and anabolic steroid. It has strong androgenic effects and moderate anabolic effects, which make it useful for producing masculinization and suitable for androgen replacement therapy. Testosterone undecanoate is a testosterone ester and a prodrug of testosterone in the body. Because of this, it is considered to be a natural and bioidentical form of testosterone.Testosterone undecanoate was introduced in China for use by injection and in the European Union for use by mouth in the 1970s. It became available for use by injection in the European Union in the early to mid 2000s and in the United States in 2014. Formulations for use by mouth are approved in the United States. Along with testosterone enanthate, testosterone cypionate, and testosterone propionate, testosterone undecanoate is one of the most widely used testosterone esters. However, it has advantages over other testosterone esters in that it can be taken by mouth and in that it has a far longer duration when given by injection.
