What a NAD+ Infusion Actually Feels Like: A Session Diary

I've administered more NAD+ infusions than I can count, and I still think the best way to explain one is to describe one — so I sat for a 500 mg session myself, kept notes the whole way through, and I'm sharing them unedited. If you've read the primer on the molecule, here's what the actual experience feels like.

Before the Drip: Setup

The protocol at our clinic: intake screening, vitals, and a Good Faith Exam on file, then the line goes in and the pump starts low. First-timers always ask about the pace — NAD+ infused too fast is what produces the discomfort people read about online. The research literature supports slow titration, and our standard is comfort-first. My nurse set the rate and told me what to expect: warmth building in the chest, and a wave feeling that tells us to slow down. Same speech I give. Fair.

The First Hour: The Wave

It came around minute 25 — a flush of warmth across the chest and shoulders, a mild tightness that's genuinely hard to describe until you've felt it. Not pain. More like your body acknowledging a molecule it recognizes arriving in force. We slowed the rate, the wave receded over about ten minutes, and I settled into what regulars call the strange part: a peculiar alertness that's nothing like caffeine. Clear, quiet, unagitated. I answered emails and lost track of the line entirely.

Hour Two: Settled In

By the halfway mark the drip was running comfortably and the sensation was mostly gone — just a faint warmth with each rate increase. This matches what the NIA's work on NAD and cellular metabolism describes mechanistically: NAD+ is involved in thousands of reactions per second, and the infusion feeling tends to fade as tolerance builds. I'd brought a book and didn't open it. The clearest way I can put it: the internal noise turned down.

The Next 48 Hours

That evening and the next two days are why clients rebook. Sleep was deep without being heavy. Morning energy arrived faster. A scheduled hard workout felt noticeably less taxing than the week prior — subjective, yes, but consistent with what our regular clients report in the NAD program. For context on dosing formats, my injections-vs-infusions comparison covers why I chose 500 mg as the sweet spot for a first full session.

The Honest Caveats

Everyone tolerates NAD differently — the wave is real for most, a non-event for some. Effects accumulate across sessions rather than peaking in one. And no responsible clinician will promise more than the evidence supports. But having both administered and now experienced it: the hour-plus in the chair is a small price for the days that follow.

Want to Try It?

Start smaller if you're cautious — an NAD injection as an add-on tells you how your body responds in minutes. Ready for the full experience? Book a session and mention it's your first NAD infusion; we'll set the pace accordingly and check in often. You're in good hands either way — mine.
