The CBD company Hit! offers a very generous free sample of their balm. I personally have tried their products and have really enjoyed everything about them.
Hit! offers more than just free samples (obviously) that I would definitely recommend. Very modern looking website and packaging with a great array of products that range from extra strength to daily usage.
