Mac V2 is a cross-bred hybrid. You may also see it sold as Mac 2, Mac2.
Public lab results give a good picture of its strength: 16 flower samples tested between 2021 and 2022 came in at a median of 24.1% total THC (the middle half ranged from 21.5% to 25.5%). That puts it at the strong end of the market, so newer consumers should start low. Potency varies by grower and batch, so always check the label.
