Ive ran tren upwards of 100mg/day & used to have massive rage/violence issues as a kid (which ive since worked thru) & doing something like this has never, not once crossed my mind. These are just the ppl that get off on being a dick and will use steroids, boose, drugs, watever as an excuse for their dickish behaviour.
id say just call him out on being a childish dick & to send that type of behaviour back to gradeschool, because you came here to wrokout nto get into playground style pissing contests, worked for me with a bitchy trenned out coworker, we were the best of pals afterwards, unironically. Sometime ppl just need to be checked on their behaviour, just dont do it while heshaving a meltdown/ outburst.
p.s. check if ur bud rly said some shit abt his fam thofirst & maybe try to explain that u had fuckall todo with it & that you hope you two can stil be cool.
p.p.s.this only works if youre not a dyel, if you are just suck it up, keep hitting the gym and outflex the guy innna mirror in a couple yrs tiem
