Do cerebral boosters stack?

I got a 30 day cerebral booster that gives +3 to all stats for buying one of the starter packs, and then I got another booster that gives +10 to all stats for one day… can I use them both at the same time for a +13 for one day? Or will the +10 overwrite the +3 and I’ll lose all the rest of the days on the +3? Or will it just be impossible to use the +10 until the +3 has run its course?

No, only one cerebral can be used at a time.
Other boosters can be used along side.

I see, thanks for the reply.

Some boosters (such as the starter booster and the daily login booster) have different booster slots, so you can use both at the same time. I’d imagine that they also stack, but I haven’t verified. It’s possible that you might just get the biggest bonus.
