Teleos sweetener?

So I've been Diy'ing for about 8 months now. I dabbled with EM for the first month and used sucralose a few times as well, but realized I didn't really need it. I'm wondering if anyone has figured out what sweetener if any at all Teleos uses in The Milk and Alpha. I taste that same sweet undertone in both. Maybe it's not a sweetener??? I picked up CAP super sweet in my last flavor order but haven't used it yet. Thanks!
