What is this?

Couple things. No idea what these samples are from 7ohBlack. Anyone know? Also… am I doing something wrong? Their powder is always awesome and this looks and tastes as great as usual. But so far every dose I’ve had (3 so far) hasn’t felt right? At first I thought I didn’t take enough. Waited like 5 hours and took like 5 of the bigger scoops which we have all agreed is close to like 100mg when weighed. It didn’t feel right. Is it in my head? I put some juice in a shot glass and pour the powder in. It sits in the middle nicely and doesn’t stick to the glass. Then just slam it down. My normal dose with tabs is like 90-120mg. Did I really not take enough? Appreciate the help
