I got my samples of this a few days ago, at 2/day. Funny enough this being my last week at my current job i've been spastic enough that I haven't worked out since sunday. So i'm itching for saturday to roll around to see what effect this has had on strength, and also to try an alternate dosing. So far i've been taking 2 a day, split by 12 hours, but next time i'm going to take an additional one preworkout.
Things i've noticed so far: from the first dose, I noticed a short term libido hike from maybe 20 minutes after taking it, lasting about an hour. I've noticed overall light sides of higher testosterone - slightly oilier skin, good mood, good sleep. The taste is nice, and there is a short term relaxation effect from taking them as well.
I'll post more here as I do my next workout, and anything else I notice
