The Thin Mint note

Leafly lists menthol among the flavors of both Gelato 45 and Thin Mint, the GSC sub-type most sources name as its parent, and Helvetic Seeds credits the mint-chocolate side of its Gelato 45’s scent to Thin Mint.3,5,9 Leafly’s editors say GSC took the throne from OG Kush to usher in the dessert-strain era.10 The Forum cut of GSC has its own guide in the Official Cannabis network at forumcookies.com.
