That mix makes no sense.
You can get away with 2x weekly injects of Tren E. But with acetate in there, it is a total waste. Blood levels will peak and fall unsteadily.
The source could have put that extra tren acetate to better use by making a combination of tren acetate 50mg / masteron 50mg / eq acetate 50mg
but if that is what you got, then try at least 3x weekly. trying to hit 400mg Tren E weekly (or close to it)
