British sports bodies are queueing up to urge caution as athletes race to prove their innocence by publishing the results of blood doping samples.
Double Olympic champion Mo Farah is one of a number of top stars set to publish their statistics in a bid to end suspicion of any wrongdoing.
But elite funding agency UK Sport has added its voice to calls for athletes to think carefully before revealing their details.

UK Sport officials say they "understand" Farah's decision in the wake of his implication in drugs allegations against his coach Alberto Salazar.
But the agency - which is pumping almost £27 million into top-level athletics for the four-year cycle up to the 2016 Rio Olympics - stressed it might not be for everyone.
A UK Sport spokesperson told Press Association Sport: "We understand the action taken by those who have chosen to be transparent at this point in time as a demonstration of their commitment to clean sport - however we must also respect every athlete's individual choice regarding the sharing of their personal medical information.
"UK Sport has a zero-tolerance policy on doping and support the work of UK Anti-Doping and the national governing bodies to ensure athletes and athlete support personnel are very aware of their responsibilities to train and compete cleanly to maintain the integrity of sport and competition."
UK Athletics fears data could be "misinterpreted" while UK Anti-Doping chief executive Nicole Sapstead said on Sunday that the logical conclusion to such a move would be that those who resisted publicising their results would be suspected.
There are no suggestions Farah has broken any doping rules, but he is keen to prove his innocence after allegations levelled at Salazar by a BBC Panorama investigation in June.
