I have a friend that lives in Austria and he comes to visit every now and again. He always stays with a mutual friend of ours. This bloke came to visit a 18 months ago and was basically the same build that I am now, not that bulky but with an athletic build. 4 months later he came to visit again and had gained 20lbs. easy. When I asked if he was using any wink-nudge "supplementation"...
"Nah bro, I only take protein and anti-estrogen". I didn't know much about supplementing at that time, so my reaction was, "Oh. Ok." Went home, did my research, discovered anti-E are popular with steroid users.
Then, 6 months later, this kid posts a picture on his Facebook. Another 20lbs. gained would be my guess. Still, he denies it, only now his sudden explosion of size is attributed to nothing but "lots and lots of hard work and protein!". Bullsh*t. Best part is, he's only 19. He's going to have raisins for b*lls and big floppy mammaries before he's my age.
Point is, most people believe him when he says he doesn't juice. Anyone that knows the slightest thing about steroids can obviously tell otherwise. So I say it depends on who asks you, base your reaction on that. If it's gym buddies, they aint gonna believe you anyway if you say you're not on gear. Your family might if they don't know that much about steroids.
F*ck it bro, end of the day, you're not going to be able to justify your steroid abuse to your family or anyone else. No matter how you explain it, they will never understand. We all have the media to thank for that. I say be straight with your friends and lie to your family. What will lose you more respect: Having your friends know you're a bullsh*tter on juice, or having them respect you for at least being honest?
