I understand why you're saying this, but you're wrong. Androgenic means aggression, muscle hardness, protection from muscle wasting when dieting and strength gains. This is not a drug only of use to throwers. Fani Halkia (2004 Olympic 400mH champion) tested positive for oral tren. Yes, of course, it lowers natural test, but so does anything exogenously given. Do you really think that Lawson knows that tren has a very high affinity for the androgen receptor and will therefore have a more pronounced effect? I doubt it. No athlete in any event would dare do post cycle therapy because they'd get caught. This is a case of oral tren if my opinion: methyltrienolone (like Halkia above).
And as someone who has taken tren, it does not necessarily cause back pumps. I got none. Compare this to dianabol and anavar and tren was easily tolerated in this respect.
Hopefully I have helped sure YOUR ignorance.
More generally, has no one thought it odd that the drugs that people claim came from contaminated food/supplements are the exact compounds they would wish to take if drugs weren't proscribed in sport. Jeez. They're just getting caught, guys.
