There are products out there usually called a cut mix where 3 types of steroids are blended into 1 vial. Not sure if this is for economical reason or for convenience. Such product I have seen is a mix of tren a, test prop, masteron in 1 vial (10ml vial, 150mg/ml). Is this an attractive product to you? Is it better to use gears separately? I'm not getting on tren a, but I'm going for test prop and masteron, so I would have to look for those separately. I was just curious how you people feel about such "mix gears". There is another one called tri-tren which is a mix of 3 trenbolones. Sounds dangerous. LOL.
