At Puffin Peptides, we work with an established Canadian manufacturer and handle packaging and fulfilment here in Canada. Keeping the process close to home gives us better visibility into quality, consistency, packaging, and the batches moving through our catalogue.
That means clearer product information, accessible batch documentation, responsive local support, and a more dependable ordering experience from checkout to delivery.
Our focus is simple: well-made research products, straightforward information, and reliable Canadian service.
Calm focus without the mental fog. Selank is a research peptide studied for its potential to support a more balanced stress response, clearer thinking, steadier mood, and improved concentration—making it especially appealing for those looking to feel composed, focused, and mentally resilient under pressure.
SELANK is supplied as 5 mg of lyophilized powder in a sealed glass vial for laboratory research. Confirm the selected vial and batch details before preparation.
Selank is the synthetic heptapeptide Thr-Lys-Pro-Arg-Pro-Gly-Pro, derived from the tuftsin sequence and studied in anxiety/stress and neurochemical research.
This 5 mg vial opens with 0.5 mL BAC water.
The default easy rule is 100 mcg = 1 unit on a U-100 syringe. Changing the water amount updates that relationship automatically.

A clear, quick look at what SELANK is, how it works, and why it is being studied.
Selank is best known for calm, stress support, mood, and clearer thinking. The attraction is feeling more settled without feeling foggy, flat, or ready for bed.
Selank is a synthetic tuftsin-derived peptide studied mainly in Russian clinical and preclinical literature involving anxiety/stress and neurochemical signalling. Small human studies exist, but the evidence base is far smaller and less internationally replicated than modern large registration programs. [1–2]
Imagine the volume on stressful thoughts being turned down a few clicks. The problems have not vanished, but they may feel easier to sort through without your mind racing ahead.
Human studies used psychometric anxiety scales rather than informal descriptions such as “turning the volume down.” The plain-English analogy is reasonable only if kept separate from the measured endpoints. [1–2]
It is usually discussed as calming rather than sedating. The goal is to take the edge off while keeping enough clarity to work, talk, and move through the day normally.
Selank has been investigated as an anxiolytic rather than a conventional sedative, but claims about absence of drowsiness should remain tied to the limited available clinical literature rather than generalized to every person. [1–2]
Stress can consume the attention you need for everything else. If the mental noise quiets down, concentrating on one task may feel easier even though Selank is not a traditional stimulant.
Cognitive and neurochemical effects are discussed in preclinical literature, but human evidence is stronger for anxiety-related outcomes than for established attention enhancement. [1–2]
Both are part of its appeal because stress, mood, and concentration often feed into one another. A steadier emotional baseline can make thinking and daily tasks feel less overwhelming.
Anxiety/stress is the clearer human research theme. Broader mood and cognition claims are more dependent on smaller studies and mechanistic/preclinical work. [1–2]
That is not its main personality. Selank is the steadier, calmer option—more ‘I can handle this’ than ‘I need to do everything right now.’
Selank is not a classical stimulant. Any “energized” or antiasthenic description should be distinguished from stimulant pharmacology and from formal performance outcomes. [1]
Selank leans toward calm, stress, and mood. Semax leans toward focus, memory, and mental drive. Think quieter mind versus sharper mind.
Selank is a tuftsin-derived peptide studied primarily around anxiety/stress; Semax is an ACTH-derived peptide with neurotrophic and neuroprotection research. Their structures and dominant research themes differ. [1–2]
Because many calming options come with drowsiness or mental fog. Selank stands out for the possibility of feeling more composed while still clear, functional, and present.
Interest comes from the possibility of anxiolytic effects without the pharmacology of traditional sedatives, but the limited size and geographic concentration of the human literature are important evidence limitations. [1–2]

Nice site and helpful chat bot. I’ll be back again.
I can’t believe it but I’ve lost 30lb. It’s been 3 months and felt compelled to write a review. I know it’s not Puffin I have to thank but their site came up in google and brought me here. Thank youuuuuu! <3

Hi! I’m Ask Puffin. I can explain peptides in plain language and help with products, prices, stock, shipping, and site questions. What can I help with?
