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.
Semax is a next-generation peptide designed to support sharper focus, clearer thinking, stronger memory, and greater mental resilience. Often described as a “brain-performance” peptide, it works with key pathways involved in learning, concentration, and cognitive recovery—helping you feel more switched on, mentally agile, and ready to perform.
SEMAX 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.
Semax is the synthetic heptapeptide Met-Glu-His-Phe-Pro-Gly-Pro, derived from an ACTH(4-7) fragment with a Pro-Gly-Pro extension.
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 SEMAX is, how it works, and why it is being studied.
Semax is best known for focus, memory, learning, and mental energy. People look into it when they want their brain to feel sharper without relying on a traditional stimulant.
Semax is a synthetic ACTH(4-7)-derived heptapeptide with a Pro-Gly-Pro extension. It has been studied in neurotrophic, neuronal-response and neuroprotection models, with a history of regional human use/research. [1]
Think about sitting down to work and actually staying with the task instead of bouncing between tabs, thoughts, and distractions. That steady mental grip is the everyday appeal.
It is discussed differently from caffeine. The goal is not a shaky rush or temporary buzz, but clearer thinking and better mental performance through brain-related signaling.
Semax does not have one fully settled mechanism. Reported effects involve neurotrophic signalling, melanocortin-related pathways, gene expression and oxidative-stress responses, with mechanisms varying by model. [1]
Memory is a major part of its research story. The interest is in helping the brain take in information, hold onto it, and bring it back when needed.
Experimental work has examined neurotrophin expression, oxidative-stress pathways, neuronal survival and learning-related biology. Those mechanisms support cognitive research interest but do not establish broad cognitive enhancement in healthy people. [1]
Both fit the same idea: getting the brain to stay engaged. People are interested during demanding work, study, problem-solving, or any period when mental stamina matters.
That is part of the appeal, especially when the brain feels tired before the day is finished. It is studied around mental resilience rather than simply forcing wakefulness.
Semax leans toward focus, memory, and mental drive. Selank leans toward calm, stress, and mood. Think sharper mind versus quieter mind.
It offers a different idea from simply consuming more caffeine: support the systems behind attention and learning instead of chasing another short-lived energy spike.
Cell and animal research reports neuroprotective and neurotrophic signals, and there is regional human literature. Much of the human evidence is smaller or less independently replicated than modern large multicentre registration trials, so evidence strength should be described accordingly. [1]
This product is offered for laboratory research only. It is not for human consumption and is not represented as a medicine, treatment, supplement or substitute for an approved product.
Confirm the selected vial and BAC-water amount, enter the target amount, then follow the preparation and storage steps.
The selected strength automatically opens with the easy starting rule of 100 mcg = 1 unit.
SEMAX · 5 mg selected
Easy rule: 100 mcg = 1 unit · Every 1 unit = 100 mcg
This calculator converts the values entered. It does not choose an amount.
This 5 mg vial opens with 0.5 mL of BAC water, creating the easy starting rule of 100 mcg = 1 unit.
If the water amount is changed above, use the updated easy rule shown by the calculator.
Do not shake the vialSlowly add the water down the inside wall of the vial, then gently swirl until fully dissolved.

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
Products in the same research area, each with its own pathway, evidence level and selectable strengths.

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?
