PHILADELPHIA -- Lane Johnson is suing the manufacturer of the amino acid he took prior to testing positive for peptides, and intends to avoid taking supplements altogether for the rest of his career, the Eagles right tackle said Wednesday.

"Yeah, I'm going after them," Johnson said following Wednesday's practice at the NovaCare Complex, declining to name the company in question because of the pending lawsuit.

Johnson is still awaiting the test results of his 'B-sample' after his 'A-sample' tested positive for peptides. If the B-sample also comes back from the laboratory positive for peptides, Johnson would face a 10-game suspension as this would be his second offense. However, Johnson and his representatives have maintained that this process could last several weeks before the results are known and he plans to appeal if he is in fact suspended.

In the meantime, Johnson admitted Wednesday that regardless of the outcome of the test he is giving serious consideration to avoiding supplement use completely for the rest of his career.

"Yeah," Johnson said. "Seriously. I Don't want to go through this stuff again. Unless something changes in the policy, I don't trust anything. That's the big risk with of supplements. The FDA doesn't regulate it. People can put stuff in there. Unless you test it, you really don't know what it is."

The No. 4 overall pick in the 2013 NFL Draft said that he isn't concerned about the impact of not taking supplements, especially when it comes to recovery, because of the risk of a potential third positive test and two-year suspension under the NFL's PED policy.

"You have cold tubs," Johnson explained. "Foam rolling. Soft tissue stuff. It's pretty limited with your body what [supplements] can do, anyway [in terms of recovery]. We'll see. I think I'll be fine though.

Johnson criticized the NFLPA earlier this month, saying that he consulted the union's app to ensure that the amino acid he was taking was an approved substance and still wound up triggering a positive test.

"Everything I've taken has been approved by the NFLPA app. That is what every player uses," Johnson said. "If you send it into the trainer of your team, all they do is read the labels, they do not test the products because it cost a lot of money to test each individual product."

As Johnson awaits the result of his B-sample and potential suspension, it seems he is going to do his best to be much more careful in the future.
