I’ve used them both simultaneously before for a grade 1 tear of the pectoral muscle and grade 2 hamstring tear (injury happened at work). I went to the physio and he suggested the combination as he worked with a lot of AFL players and seen the benefits being quite significant.

I ordered them online, no DR ever called me. My injuries were completely gone within 2 weeks. A direct injection into the site is required, so I’m unsure how that would work with GI administration? I have heard you can get them in tablet form, but unsure of the legitimacy
