With Dynamis, Semax and Selank come with a provider who prescribes them, a licensed pharmacy partner that fills the prescription, and a Personal Health Coach who stays in touch.
You take Semax and Selank as a nasal spray, so there are no injections to learn or schedule. Your provider sets how much you use and how often, based on your health history.
Dynamis prescribes Semax and Selank together in a single nasal spray, so you use one product instead of two.
If you’re considering your options for dealing with stress and/or anxiety, Selank is the part of the spray aimed at it. Researchers have studied Selank for anxiety, including in people with generalized anxiety disorder.
If you want sharper thinking and steadier focus, Semax is the part of the spray aimed at that. Researchers have studied Semax for brain function, including in healthy adults using a nasal spray.
Semax and Selank are two investigational, lab-made peptides studied mainly in Russia. Semax has been studied for brain function and Selank for anxiety.
At Dynamis, you get both in one nasal spray, prescribed by a provider and backed by your own Personal Health Coach as part of our peptide therapy.
You start with a kickoff call and a health history, with no pressure to commit to anything. Nothing is prescribed until a provider has reviewed your history.
After the call, a board-certified provider decides whether the spray fits you, then sets the dose from your history and any labs ordered.
Once your provider writes the prescription, a licensed U.S. pharmacy partner fills it.
Your Personal Health Coach checks in and answers your questions within 2 hours. Your provider adjusts the plan when needed.
A kickoff call is the first step: you ask your questions and share your health history, with no pressure to commit. A board-certified provider then reviews that history and decides whether the spray fits you, and if it does not, we will tell you plainly. Book your kickoff call to get an answer based on your own labs and health instead of a cookie-cutter solution.
Yes, a provider can prescribe them together, and your health history decides whether that makes sense for you. Each peptide has been studied on its own, so your provider sets your dose individually after reviewing that history.
Researchers have studied each peptide on its own, mostly in small studies in Russia: Semax for brain function, including a 2018 brain-imaging study in 24 healthy adults, and Selank for anxiety. That research is early, so it cannot yet show how well either one works for most people. Your provider reviews your health history to decide whether the spray fits you.
Yes, the spray is prescription only, so a provider has to review your health history first. A kickoff call is the first step, and the provider decides from there whether it fits you.
They are two separate peptides with different research histories. Semax has been studied in healthy adults with brain imaging and in people recovering from ischemic stroke. Selank has been studied against another drug in people with generalized anxiety, and separately in rats. Dynamis prescribes both together in one nasal spray, and your provider decides whether that combination suits you.
An FDA advisory committee reviewed Semax in July 2026. Adding a substance to FDA’s list of bulk drug substances that pharmacies can compound takes rulemaking, so a committee vote is not a final listing, and Selank was not on that meeting’s agenda.
