Shoyu: Japanese soy sauce is a popular ramen seasoning in the Kanto region of central Japan, originally emanating from Yokohama. Traditionally it's paired with clear to brown chicken, seafood, and occasionally pork or beef-based broths, though these days shoyu is used willy-nilly by ramen chefs throughout Japan.
IM injections can be given in a large muscle in the buttock, upper arm, or thigh. It is best to use the buttock or thigh instead of the arm if: the amount to inject is more than 2 ml (2 cc). (But you should never inject more than 3 ml (3 cc) in a single dose. Use 2 injections instead.)
You need to know what concentration your test-E is before you can know how much to take. Typically (but not always) it comes as 250mg/ml. That means that every ml (or cc, same thing) that you inject will contain 250mg of testosterone enanthate. With test enanthate, you want a cycle to be in the 8-12 week range. If your gear is 250mg/ml, you'll need 2 bottles for a decent cycle.
