seeking advice

Hi everyone, first please excuse my ignorance and language because iam new to Canada and enlgish is not my first language.

i work out and i also lift heavy stuff at work, started to feel some pain in my wrist and elbow joints. i want to try CBD for that. i also found out there is another product called CBG. so my question is, is there a certain brand in canada i should go with?. and what doseage?. sorry again if i sound ignorant and thanks in advance for the advice. by the way i have never tried any thing before.
