You should try it fresh. Menthol doesn't really need to steep nor does stawberry. They will mellow with age but should be worth a vape fresh. Plu you can see if it betters with age. I personally like the sharpness of menthol fresh
Sold! Don't have to tell me twice. Lol. Tried it. Not bad. A little too heavy of strawberry and not enough menthol. So added some drops of menthol, will finish vaping the little bit in my tank since the heavy strawberry flavor is still pleasant to me, and then try round 2 later.
