What's Included
Daytime focus, cellular renewal, and brain energy in one order, each chosen to complement the others.
Focus & Mood · Nasal Spray
A neuropeptide duo delivered intranasally for rapid absorption, designed to support mental clarity, focus, and balanced mood. No needle for your daily dose.
Cellular Renewal
A peptide designed to target senescent (aged, non-functioning) cells, supporting cellular renewal and healthy brain aging. 30mg / 3mL.
Brain Energy
MOTS-c and NAD+ together in one vial, pairing mitochondrial support with cellular energy to help fuel brain metabolism and cognitive resilience.
A dial-a-dose pen for precise, consistent dosing of your injectables. Your provider includes instructions for each product. Includes one pack of 24 pen needles for every vial: 1, 2, or 4 packs depending on your stack size.
Every stack includes one NEST reusable injection pen and one 24-count pack of pen needles per vial. Nasal sprays match your vial count.
The Science
Semax is studied for supporting focus, attention, and neuroplasticity through BDNF and neuroprotective pathways. Selank supports a calm, balanced mental state without sedation. Together in one nasal spray, they are designed for clear, steady daytime focus.
Senescent cells are aged cells that stop working but linger, and they may contribute to age-related inflammation and cognitive decline. FOXO4 is designed to support their natural clearance, helping maintain a healthier neuronal environment.
Your brain uses about 20% of your body’s energy. NAD+ fuels energy metabolism and neuronal repair pathways, while MOTS-c supports mitochondrial efficiency and metabolic resilience to help sustain mental performance.
What to Expect
First Few Weeks
Some people notice improvements in focus, mental clarity, or mood, particularly with Semax/Selank.
Several Weeks
Mental energy and resilience may continue to build as the stack becomes part of your routine.
Several Months
Benefits tied to neuroprotection, senescent cell clearance, and mitochondrial support may continue to develop.
Individual results vary. Best results come alongside quality sleep, brain-healthy nutrition, regular exercise, and stress management.
FAQ
Semax/Selank Nasal Spray, FOXO4, MOTS-c/NAD+, a NEST reusable injection pen, and pen needles.

Yes. Every Focus Stack order is reviewed by a licensed provider before fulfillment. If your provider determines the stack isn't appropriate for you, you receive a full refund automatically, with no return needed.
Individual responses vary. Some people notice improvements in focus, mental clarity, or mood within the first few weeks, particularly with Semax/Selank. Benefits related to neuroprotection, senescent cell clearance, and mitochondrial support may continue to develop over several months of consistent use.
Semax/Selank is typically used in the morning and/or early afternoon to support daytime focus. Avoid late-evening use so it doesn't interfere with sleep. FOXO4 and MOTS-c/NAD+ are injections on the schedule your provider sets.
The nasal route is studied for its potential to provide more direct access to the central nervous system, which may support a faster onset. It also means no needle for your daily dose.
No. The Focus Stack is for anyone looking to support cognitive performance, whether you have demanding work or studies, want to manage age-related changes, or simply want to stay sharp over time.
Many patients use the stack alongside other cognitive support supplements. Always share your full regimen with your provider so they can check for interactions.
Some people experience mild nasal irritation with the spray, or mild injection-site redness or bruising with the injectable products. Other possible effects vary by compound. Your provider will review potential risks with you.
This protocol may not be appropriate during pregnancy or breastfeeding, for people with certain neurological or medical conditions, or for those taking specific medications. Always discuss your complete medical history with your provider.
