That’s up to you. It’s a personal decision to determine if testing matters to you or not.
The bigger problem is that Gu doesn’t make it clear that his new crosses are not tested. When they are tested it just means his paying customers have grown them. He makes up stories saying he’s selling testers due to demand, except he’s been doing this for a long time now. Plus, while some new crosses are labeled testers on the site, others aren’t.
Finally, the MAC1 cross. Gu was planning on selling the MAC1 cross. I get the impression he’s decided not to because I made it abundantly clear that MAC1 crosses are garbage. They have very low germ rates, and they throw awful runty, mutant offspring. I saw someone on IG pop 50 seeds and only ended up with one viable plant in the end. Those would’ve been sold, completely untested.
Bodhi has proven males and females. He still tests every single cross he sells. Because, even with good genetics, not all crosses are good crosses.
As for selections, I prefer to support breeders that are actually advancing the field of cannabis breeding. Breeders that select their own male, and try to create something new. If that doesn’t matter to you, cool. Just stop pretending that GPS belongs in the same category as a breeder who actually is putting in the work to develop something new.
