Gymshark 

Tell me you take sarms or steroids without telling me or lying that you’re a natty.

That’s just a stereotype yes. But it’s a stereotype for a reason bc guys who wear Gymshark are infact according to a study, more likely to be enhanced, spray tan & grease themselves as well as going to planet fitness just to check themselves out hoping girls are noticing them.
