I got 5mg/ml into extra virgin olive oil.... it takes a little bit of shaking but it will go in.
Many methyls can be mixed using straight extra vigin olive oil, here are some examples that i have been successful with:
methyl1test -10mg/ml
m-4ohn- 5mg/ml
M-4oht - 5mg/ml (this one took some time)
m-1,4adiol - 10mg.ml
m-5aa 10mg/ml
m-4ad 15mg/ml
methyldienolone - 5mg/ml
