Boldenone Undecylenate 300mg/ml
and
trenbolone Acetate 100mg/ml

what s the best way to cycle this?

my goal is to gain some size (musclemass)

guy that sold me this said i would 'blow up"...

he says to take the Boldenone once a week 1cc
and tren 1cc twice a week

any advice?
i wanted to ask about the brand but i guess that s against the rules...

any advice would be appreciated... thanks
