I didn’t notice much at first, but after two weeks I must’ve hit some sort of critical mass. I had more energy, workouts felt better, I felt more even throughout the day. My sleep definitely got better, which may be what I can attribute most of the positive effects to. Either way, worth it. Just wish it was a little more affordable. Great overall.

I am three weeks into taking Eternus per schedule. I do perceive an increase in sustained physical energy and an increase in cognitive function. Best of all Eternus has helped with sleep duration. At 72 years of age, my sleep time was short and not deep. I have added an hour of sleep and am experiencing a deeper non-dream state.

In terms of clearer thoughts, the product seemed to work relatively well for me. Sleep didn’t seem to be affected positively nor negatively. Overall I enjoyed the effects of the product. If it is released soon, I plan on ordering it and diving deeper with some other testing methods.

I would like this product without the caffeine. Felt more mellow and more productive. There was an initial buzz that was disconcerting but in 2-3 hours that effect went away. I would like the caffeine free version because I don't like a jittery feeling at all. Did like feeling relaxed and not feeling like I need to do something now--can wait until another time. Has a tendency to smooth out the "shoulds" in your life.

I didn't like the new formulation as much as Original Stack, which I now take (although I know it is to be discontinued)

I could tell a little difference

On days 4 and 5 of taking the samples, I felt a strong pressure in my head when I laid down for a nap in the afternoon. It wasn't painful, but it wasn't pleasant either. The first few days I felt awesome, but the effect seemed to diminish with time.

I monitored my blood pressure while taking it and I didn't have any changes to it

This product made me feel sharper and more focused than normal. The only cons were brief feelings of irritation when distractions came up and I didn't enjoy the taste (as expected). Overall I would take this product again.

Day 1: seemed to have a few minor side effects Day 2: less side effects but crashed around 4pm Day 3: better than other days and seemed to provide energy Day 4: felt well and was able to enjoy the day Day 5: went well again, tad more energy.

Smooth effect, felt good

I think the low quality of sleep is skewing today’s input. The taste could be improved with chai spice I think.

There is definitely a caffeine buzz associated with this and although small challenging tasks are handled well, more complicated tasks I felt were inhibited by a more caffeinated feeling. Physical reactions were faster although slightly less precise, again due to the caffeinated effects

The flavor was not great, but ok otherwise

I feel a slightly more energetic, motivated, and light hearted. Overall, the effects are slight.

More energy

Working a stressful shift at urgent care, no real noticeable cognitive benefits. Maybe a little more anxious than normal

noticeably sharper

I am more a fan of the capsules rather the drinkable powder. I think the product works well for most of the day. I can feel it wearing off later in the day. Not just why that is. Is there an expectation that this last 6 or 8 or 12 hours? Thanks!

My sleep the night before was mediocre so I will need the additional days to make a better assessment, but so far it felt like the product worked well at first but wore off faster than the capsules. This could be due to my previous night sleep being just mediocre.

I felt focused when necessary. Did not feel stressed. No nausea. No problem getting to sleep.

I don't feel any change too significant. If anything, I do feel at a loss for words and unable to articulate what I normally am. I'm not sure if its the product or not, however; I do feel more awake and slowly starting to feel a come up of clarity.
