EQ has such a long half-life (like 2-3 weeks) that 2 injection per week are planty. Even 1 a week would not be all that bad.
There is no reason to go like 3x a week, or EOD with EQ .......... except .... if you are doing high doses, and you just need to do SO many injection in order to bascially get it all administered.
Like, some EQ brands are onll 50 mg/ml. These guys doing like 800 per week - thats 16 ML (or CC) per week! That would require a good 4 injections per week!
This is also a good reason to go with higher-concentration EQ brands such as Ttokkyo. At 200 mg/ml, this keep the volume down.
