NBA players have agreed to offseason testing for performance enhancing drugs for the first time as part of the new labor deal that is being balloted. The NBA did not test players previously during its July-September offseason.

Billy Hunter, Players’ union executive director, sent a memo, obtained by The Associated Press, to players detailing changes to the labor deal and recommends they ratify the agreement.

Beginning in the 2012-13 season, players can be tested up to two times during the offseason for steroids and performance enhancing drugs according to the memo. The memo also disclosed that a majority of players would be tested no more than four times throughout an entire year, and that no tests may be given at the arena on the night of a game.

No matter what, NBA players will face additional testing if the deal is ratified.

The memo was not very much clear about testing for human growth hormone, saying only that a committee would be studying the “possibility of an HGH testing program.” NBA spokesman Mike Bass, however, insisted that both sides have agreed to HGH blood testing, subjected to the process being validated by a “neutral committee of experts.”
