Purlyf CBD has introduced three half gram Cartridges with 200mg of CBD in each pen. Conveniently Hybrid, Sativa, and Indica, a brand that allows you to use the product throughout the day at anytime. OG Kush (Relax)- is Purlyf's Indica option, the OG Kush cartridge is perfect for night time or people with insomnia, if you have restless nights and are having trouble getting to sleep at night this cartridge is just what you need. Pineapple Express (Balance)- is Purlyf's Hybrid option, Pineapple Express is a great cartridge for evening times, when you get off work and you need to unwind from a long day. This cartridge is my personal favorite because it is just the right balance of body and mind. The last Cartridge Purlyf offers is Sour Diesel (Uplift)- is Purlyf's Sativa Option, Sour Diesel is a great Cartridge to use to get the day started. I love using my cartridge in the morning time to get that burst of energy I need, I am not ashamed to admit I am not a morning person, but I have noticed a change in my morning routine. Instead of walking straight to the coffee room first thing when I get into the office, I have noticed I am able to hit my Purlyf Sativa pen a couple times throughout the day and I don't find myself missing my morning coffee (monday mornings can be 50/50). I do use CBD throughout my day because I have personally noticed a significant change in mood as well as overall well being, however with these pens they have just the right amount of CBD in each hit to still notice a significant difference. I have come across a lot of companies with CBD cartridges that just simply label there product "CBD" but don't allow you the opportunity to choose whether it is going to lean more towards Indica, Sativa or Hybrid. Which is one of the many reasons why I love this brand. If you are in the market looking for a reasonable priced CBD product to try out, I highly recommend you go with Purlyf. I can say from first hand experience you will not be disappointed with this product.
