Research peptides for laboratory use

Q: Are these peptides suitable for human use?

No. All products are supplied exclusively for laboratory and research purposes and are not intended for human consumption.

Q: How is purity verified?

Every batch is analysed by HPLC for purity and identity. Purity is ≥99%.

Q: What is the difference between a pen and a vial?

A vial contains lyophilised powder that you reconstitute yourself, giving full control over concentration. A pen is pre-filled and uses a click-dosing mechanism.

Q: How quickly is my order delivered?

We ship with DHL Express. Within the EU orders typically arrive in under 48 hours, fully tracked.

Q: How should the products be stored?

Store lyophilised peptides cool (2-8 °C), dry and protected from light. Refrigerate after reconstitution.

Fat burning

GLP-1, GIP and glucagon agonists: the most studied route in research into fat metabolism and energy balance. Retatrutide acts as a triple agonist on all three receptors; Cagrilintide is an amylin analogue often studied alongside it.

Cognition & focus

Semax and Selank are short peptides from Russian neuropeptide research. They are studied in the context of BDNF expression, attention and stress response - a completely different area from the metabolic peptides.

Energy & longevity

NAD+ is a coenzyme central to research into mitochondrial function and ageing. MOTS-c is a mitochondrially encoded peptide studied in the same field - which is why it also appears under fat burning.
