Combos that include Mass FX and other AX products?
Mass FX + Hyperdrol X2
Mass FX + Hyperdrol X2 + Retain 2
Mass FX + SDNG w/ aPCT added after SDNG
Dosing is usually 4 of each per day, spread out evenly and taken with food.
Though, on a personal note, I loved running MFX solo! As a standalone, it's a great product.
Hope that helps!
