NAD Injection Physical Responses

9 replies8 peopleMay 4, 2026☆ Follow
Summary

Does pinning NAD produce an adrenaline-type rush and do different batches or methods change the effects?

Several users report an adrenaline-like rush or energy surge starting within a minute or two of injection and lasting up to ten minutes, though not every time and not for everyone. One person noted their spouse feels nothing at all. Switching to IM administration was suggested as possibly stronger than subq, and one user planned to test it. Discussion also touched on niacin as a NAD precursor and possible liver concerns with high doses.

What this discussion establishesWhere people disagree

Some users experience a clear rush while others (including one spouse) report no sensation whatsoever.

Still open

Whether absent rush indicates a dud batch, what constitutes a safe long-term niacin dosage, and how administration method actually alters the response.

Nothing here is advice.

Hi everyone, I'm curious if injecting NAD is supposed to cause an adrenaline-like rush that lasts a few minutes. I've noticed different physical responses between batches, with some lacking that feeling. Can anyone share their experiences? Much love

For me it definitely produces an energy rush. Since this is my first kit I have no way to compare different sources.

Did you switch how you're administering it? I've heard IM produces a stronger initial effect than subq. Also how is it going for you?

I experience a sensation in my upper abdomen or lower chest that resembles an adrenaline rush. It begins a few minutes after the shot and continues for about 10 minutes. My wife reports feeling nothing at all.

I get something like an adrenaline rush about a minute after injecting. It goes on for several minutes, though not consistently.

Hey! I hadn't considered that but it sounds worth trying. I'll test it today and let you know if I notice any changes. Maybe this batch is off because the powder appears partly melted and then recrystallized.

Vitamin B3, which is niacin, is the main B vitamin that helps create NAD. Some claim that pushing through 30 days of the niacin flush will give plenty of NAD and remove that side effect. Bro science or not?

I recall reading that getting too much of this vitamin isn't great for the liver. Does that mean the damage link is bogus? It does look like big amounts cause liver harm.

I inject 25 mg every day. Without it I get very drowsy in the afternoon, but it provides energy for the gym after work.

Do you know what a safe dosage would be? Every multivitamin I've used seems to have those excessive amounts mentioned in the article you linked. That's not good.
