The way I see it, those ignorant bastards just screwed you out of some hard earned cash and perhaps even an opportunity at making some real gains.
1st of all, if they tossed them without your consent, even if you did not retrieve them, they owe you maximum market value for each amp. I'd be nice and say $15 each.
2nd, they just probably spit some statistics and horror stories about roid use that everyone around here has heard and can either tell you how to prevent, or discredit. If I were you, I would feel manipulated.
3rd, I respect your decision to stay all natural. It isn't easy. Someday, if you feel like you can't reach any further, you might want to reconsider.
And lastly, but most importantly, you are on the dark side my friend. "One step down the dark path, and forever will it dominate your destiny." You aren't out of it just yet.
Good luck with your training!
