Well Nimbus sent me a tub of Poseidon which I have used for the past two days and will continue until the small tub runs out.
Dosage: 1 scoop about 3-5 times a day so far.
Effect: Just in the few days I've been using Poseidon, I do feel slightly better overall. It could and probably is just due to better hydration, but either way, I feel like I have more energy. I took 1.25 scoops first thing in the morning yesterday and the niacin flush was insane. First I've ever experienced that.
In the gym: I've been mixing a scoop or two in with my intra-workout drink as well. Can't say I've noticed any improvements since Poseidon in the gym though. Maybe a slight improvement in stamina.
If Nimbus would ike anything specific commented on, please let me know and I will do my best. I will update more in the next day.
