I don't see the noticeable size differential in his lat that you're referring to. But neither picture is really a good shot of his lats anyway. Adding size to one muscle group doesn't support the theory that he's juicing either. His arms, shoulders, and chest appear to be the same size or at least within the range of what could be achieved with six years of lifting.
While it's not a perfect side by side comparison, I tried to find a picture with a posture as similar as possible to yours. Any size gain from 2018 to 2024 could absolutely be achieved with a well-monitored diet and TRT or HRT, even in his mid-40s. This is especially feasible if you have the financial resources to support it, which he does.
Whether he's clean or not, I don't know. However, any gains from those two pictures is minimal and definitely not substantive of supraphysiological doses.
Also, since when does doing interviews implicate you for juicing?
