Hi Seabreeze,
The main reason we went with the 500mg balm first was price. The 1000mg container is $15 more than the 500mg, when you're only talking a 1oz container $50 is pretty pricey. We figured we'd try the 500mg first to see if it works at all, then if we needed to go up in strength we would. Both my wife and I are experiencing a high level of pain relief from the 500mg for both muscle and joint pain, so we figured we'd stick with that for now. We both average about 4 to 6 hours pain relief from one application. It doesn't take a lot of balm to treat an area, just a small dollop on your finger tip to rub in. We are using the "calming purple" balm, it has a pleasant (not overpowering) smell and isn't oily which are both pluses. There is no menthol smell or warming affect, which we like. I can't say anything about the lavender scent because I haven't purchased it. We are finding that a 1oz container will last us about 3 to 4 weeks if we use it sparingly, around 2 weeks if we use it a lot. My wife uses it on her lower back in the am and the pm daily. It gives her a lot of relief and helps her sleep better at night. I've used it to help with my arthritis joint pain with success as well.
I believe Gogreen products are sold at dispensaries, I think that's where Gary got his in Oregon and that's how I found out about it. The main reason I went with the GoGreen product was Gary's recommendation, also after doing a little research online I found that the GoGreen products contain one of the highest concentrations of CBD for the price. I found some balms and drops that were around $100 per oz. Also GoGreen lists independent third party test results on their site which made me feel more comfortable about the truthfulness of their ingredients. Their customer service is pretty good too. I've used the online chat twice with good results.
Hope this helps, good luck!
