Hi there! I purchase quite a bit of PLR, but tend to focus on content about digital marketing and online business rather than physical therapy and sports medicine. My go-to sources are AllPrivateLabelContent.com, ToolsforMotivation.com, BestQualityPLR.com, CoachGlue.com and ContentSparks.com.

Tiffany Lambert's PLRMinimart.com has a bunch of health and wellness content at very good prices, and she's a stand-up ethical online seller. Another one I know and trust in the health/wellness field is JR Lang at InternetSlayers.com.

Hope this helps you! Best of luck.
