The two I like and use are from GC.
TPP/NPP/Mast P 100/100/100
I just add a little extra test and it's great. I like the 1:1 NPP and mast, and the TPP is great too. I just prefer higher test than nandrolone
Tren ace/mast prop 150/150
Ever since doing it the first time, I prefer 1:1 tren to mast ratio. Then add your test of choice and it's perfect. It has a little bite because of the concentration, but I prefer the soreness from high concentrations over the soreness of high volume injections by a long shot. It's either something like 1mL of each plus test EOD (3mL) or .7mL plus test. I'll take the lesser volume any day of the week because past 2mL it starts causing issues
Outside of that, I haven't found any I like. You almost always have to add some test to blends, but those two have the ratios I prefer
