Best Peptides for Energy for Women

The three energy peptides worth asking about are NAD+, sermorelin and MOTS-c, and the right one depends on why you're tired. NAD+ has dozens of human studies behind it, mostly on pills the body turns into NAD+. Sermorelin prompts your body to release its own growth hormone, which supports deep sleep. MOTS-c is the newest option, with promising animal data and human data that so far only looks at the MOTS-c your body makes.

Which energy peptide fits my kind of tired?

Match the peptide to the reason you're tired. No study has compared NAD+, sermorelin and MOTS-c with each other, so this table matches each one to a goal and doesn't rank them.

Does NAD+ give you more energy?

NAD+ has a large body of human research behind it, but most of that research tests pills, not the injections and sprays you can use at home. NAD+ is a molecule every cell uses to turn food into energy. That's why it's the first name most women hear when they want more energy.

Researchers have pooled 27 studies of NAD+ precursors on fatigue and physical performance. Precursors are pills the body turns into NAD+. Twenty-five of those studies were randomized trials, and together they covered 1,599 people, with average ages from 24 to 83, most of them middle-aged and older. In one study, healthy middle-aged and older adults took nicotinamide riboside every day. Nicotinamide riboside is a form of vitamin B3. Their NAD+ levels rose, and they tolerated it well.

Injections and nasal sprays deliver NAD+ itself, so the pill results don't automatically carry over to them. Ask your clinical team which form fits your routine and your goal.

A clinic IV drip is the pricier route. A single NAD+ IV session runs into the hundreds of dollars, while a month of at-home NAD+ starts at $99 to $119 (NAD+ therapy costs).

Is sermorelin better if poor sleep is what's draining me?

Sermorelin is the peptide to ask about when your tiredness starts at night. Sermorelin is a short piece of the hormone that tells your body to release its own growth hormone. Growth hormone promotes deep sleep (also called slow-wave sleep), the phase that matters most for physical recovery. If you wake up feeling like you never slept, that's where sermorelin's mechanism points.

Sermorelin also has a clear prescribing path. It was FDA approved for children's growth problems under the name Geref. The maker stopped selling it in 2008 for business reasons, not safety ones. Because of that history, a 2026 review says FDA generally allows a physician to prescribe sermorelin and have it legally compounded.

Common side effects are facial flushing, headache, dizziness and hives where you inject. Ask your clinical team what to watch for.

Growth hormone's anti-aging reputation is still debated. Short-term use of growth hormone and the peptides that raise it helps with some conditions. Animals with high growth hormone for several years tend to live shorter lives. Ask your clinical team how long you should stay on sermorelin.

What does MOTS-c do for energy, and is it too new?

MOTS-c is the frontier pick. It's new enough that human data so far comes only from studies of the MOTS-c your body makes, and it's for you if you want to be early. MOTS-c is a peptide made by your mitochondria (the energy makers in your cells). Researchers call it an exercise mimic because it helps your body use sugar and handle insulin. In mice on a fattening diet, MOTS-c prevented weight gain and insulin resistance.

Exercise raises your own MOTS-c. In a 16-week study of breast cancer survivors, aerobic and strength training raised MOTS-c in non-Hispanic white women but not in Hispanic women. In the women whose levels rose, the rise went along with less fat, lower body weight and more lean muscle.

So far, human data only links natural MOTS-c levels to insulin sensitivity. FDA says it "has not identified any human exposure data on drug products containing MOTs-C administered via any route of administration" and that it "lacks important information regarding any safety issues raised by MOTs-C, including whether it would cause harm if administered to humans." If you want to be early, MOTS-c is the one to ask about, and your clinical team decides whether it fits you.

If your tiredness is tied to extra weight, the same 2026 review names GLP-1 medicines as a safe and effective alternative to MOTS-c for weight and metabolic goals. Hot or Nothing plans include GLP-1s such as semaglutide and tirzepatide.

One r/Peptides user taking MOTS-c asked whether SS-31 (elamipretide) is "mandatory" alongside it. SS-31 is FDA approved only for a rare genetic muscle disease. Its safety in healthy people who use it for energy or performance hasn't been studied.

Should I take more than one peptide for energy?

Start with one. One r/Peptides user taking a long list ended up more wired than rested. They wrote, "I'm aware- I'm taking A LOT." They added, "Some days I'll have good energy, but most days I feel tired but wired. Brain never slows down."

A 2026 review describes how social media and friends' recommendations push people to keep adding peptides, until they're taking many drugs at once.

With one peptide, you can tell what's working. Note your afternoon energy and your sleep for a few weeks before you change anything. Tell your clinical team everything you already take, including GLP-1s and supplements.

Take the quiz and tell us what's draining you: all-day fatigue, bad sleep or a slow metabolism. Your clinical team uses your answers to see which energy peptide fits your goal and your plan.
