Examine.com: L-Theanine + Caffeine research summary -
"180mg natural caffeine for smooth energy"
180mg caffeine is a clinically effective dose. PubMed confirms strength and cognitive benefits at 200mg — this is close.
PubMed: Caffeine dose-response studies (Examine.com summary) -
"Boosts metabolism via green tea and lychee extracts"

Consumer advice
If you want a clean energy drink without artificial colors, aspartame, or a sugar crash, this is a solid option. The caffeine + L-theanine combo is the real value here — it's clinically validated. Skip the subscription if you're just trying it. Compare to Celsius (~$2/can at Costco) or GHOST Energy for similar formulations at lower prices. Don't buy this for the "metabolism boost" — that claim is weak. Buy it if you like the taste and want a cleaner energy drink.
