Longevity & energy

The new vocabulary of aging well.

NAD+, sermorelin, glutathione, MIC+B12, methylene blue — the peptide and IV-adjacent therapies people are turning to for energy, recovery, sleep quality, and cellular health. Underregulated, fast-moving, easy to get wrong without coaching.

Who this is for

Adults 35+ optimizing energy, sleep quality, recovery, or cognitive sharpness. Often combined with weight management or hormonal protocols.

What's covered

Specific treatments. Honest details.

NAD+ (injection or nasal spray)
Nicotinamide adenine dinucleotide. Cellular energy cofactor. Supplementation is debated in the literature — but the subjective energy reports are consistent enough that it's become a major category.
Sermorelin
Growth hormone-releasing hormone analog. Oral tablets or subcutaneous injection. Used for sleep, recovery, and body composition in adults 35+.
Glutathione
Master antioxidant. Oral, IV, or nebulized. Adjunct to skin clarity, detoxification protocols, and inflammation work.
MIC + B12 (lipotropic)
Methionine + Inositol + Choline + B12. Injection blend popular for energy and metabolic support, often paired with weight loss programs.
Methylene Blue
Mitochondrial electron-transport modulator. Niche but growing for cognitive and energy use cases.
Sisu's role

This category is full of marketing dressed up as science. Sisu won't tell you peptides will make you live forever — but it will help you track if NAD+ actually changed your energy, log your sleep deltas on sermorelin, and notice if a stack is or isn't worth the money.

Common questions

What people ask about longevity & energy.

Are these peptides FDA-approved?+

Sermorelin is FDA-approved for pediatric growth hormone deficiency; adult anti-aging use is off-label. Most peptides in this space are compounded under 503A pharmacy regulations during shortage status.

Does NAD+ actually do anything?+

The biochemistry is real — NAD+ levels decline with age and supplementation raises serum levels. Whether that translates to "I feel better" is individual. Sisu helps you decide via your own data, not marketing claims.

Is this safe long-term?+

Most of these therapies don't have decades of safety data the way standard drugs do. The honest answer is: track yourself, work with a licensed provider, and don't chase every trend.

Will my insurance cover this?+

No. These categories are universally cash-pay through telehealth or wellness clinics. Sisu helps you compare prices across partners so you don't overpay.
