After 8 weeks of hands-on testing, we break down everything you need to know about Strut's NAD therapy — the results, the cost, the science, and whether it's worth it for busy American men who want their energy and edge back.
312+ verified reviews. Here are four of the most detailed, honest accounts from men who've actually used Strut's NAD therapy injections.
"I was skeptical — really skeptical. I've tried everything from testosterone creams to a dozen different supplements. But after my first month of Strut's NAD therapy injections, something genuinely shifted. My 3 PM wall just... stopped. I'm sharper in meetings, I'm waking up without that groggy cloud. My wife noticed before I did. Four months in and I'm not going back."
"The online process at Strut is shockingly smooth. I filled out the health questionnaire in about 12 minutes, got doctor approval in under 48 hours, and the injection kit showed up at my door a few days later. Month 3 now and my mental clarity is something else. If you're a guy in your 40s running on fumes, you need to try this."
"I went into this thinking it was biohacker hype. I'm a 58-year-old cardiologist and I was fully prepared to be unimpressed. What I found was pharmaceutical-grade compounding, legitimate physician oversight, and genuine results in my energy and recovery times. Six months in and I've recommended it to colleagues."
"Solid program, mostly great. The doctor actually reached out after month one to adjust my protocol — that was unexpected and appreciated. Four stars only because week one had some minor flushing and mild nausea (totally normal, went away by week two). Month two: markedly better sleep, better gym recovery, and I feel like I'm running at a higher baseline."
Strut's NAD therapy is a physician-supervised, injectable NAD+ (Nicotinamide Adenine Dinucleotide) program delivered through Strut Health's telehealth platform.
NAD+ is a coenzyme that exists in every single cell in your body. It's absolutely essential for energy production at the mitochondrial level, DNA repair, and activating the longevity proteins called sirtuins.
Here's the brutal truth: your NAD+ levels drop roughly 50% between your 20s and your 60s. That decline is one of the primary biological drivers behind the fatigue, brain fog, slower recovery, and general "aging" feeling that starts creeping in for most men after 35.
What makes Strut's NAD therapy different from the supplement aisle is the delivery method. Injectable NAD+ bypasses your digestive system entirely, delivering pharmaceutical-grade NAD+ directly into your bloodstream for maximum bioavailability.

NAD+ powers ATP production in your mitochondria. More NAD+ means more efficient, consistent energy without the crash of stimulants.
NAD+ supports brain cell energy metabolism. Most users report sharper thinking and less brain fog within 2–4 weeks.
NAD+ is a required cofactor for PARP enzymes — the body's primary DNA repair machinery.
NAD+ activates sirtuin longevity proteins (SIRT1–SIRT7) that regulate cellular health, inflammation, and biological aging.
Better cellular energy means improved output during workouts and faster recovery. Many athletes notice improved endurance at 4–6 weeks.
NAD+ regulates circadian rhythm at the cellular level. Users commonly report deeper, more restorative sleep after 4–8 weeks.
NAD+ plays a central role in glucose metabolism and insulin sensitivity, supporting healthier body composition over time.
NAD+ supports cellular stress response systems that help your body adapt from oxidative damage, inflammation, and environmental stressors.
Emerging research suggests NAD+ may support vascular health through sirtuin activation — relevant for men over 45.
Injectable delivery bypasses first-pass metabolism entirely — unlike oral NMN or NR supplements. Predictable, high bioavailability every dose.

"The best investment I've made in my health in the last decade. I wish someone had told me about injectable NAD+ therapy five years earlier."
Strut's NAD therapy is a physician-supervised injectable NAD+ program — meaning NAD+ is delivered directly into your bloodstream via subcutaneous injection, bypassing your digestive system entirely. This is fundamentally different from oral supplements like NMN or NR, which must be converted through enzymatic pathways that are rate-limited and variable.
Strut's NAD therapy starts at $149 for a 500mg vial. Ongoing programs range from $149–$299/month. This represents roughly 75% savings compared to IV NAD+ therapy at a wellness clinic ($400–$600 per session). HSA and FSA funds are accepted.

Most users report improved energy within weeks 1–2. Mental clarity typically emerges at weeks 2–4. Better sleep and physical recovery at weeks 4–8. Full cellular NAD+ restoration and compound longevity benefits develop over months 2–6 of consistent therapy.
NAD+ therapy may not be appropriate for those who are pregnant or breastfeeding, have known allergies to NAD+ components, have active cancer or recent malignancy history, have severe cardiovascular conditions, are under 18, or have severe kidney or liver disease. Strut's physician review screens for all of these.
