What's inside

Bundle

1

Semax

emax is studied as an ACTH fragment analogue that can nudge cell signaling and gene expression programs in the nervous system. Reported readouts include higher BDNF and TrkB activity in hippocampal tissue, quieter inflammatory gene signals after ischemia reperfusion stress, and shifts in nitric oxide and oxidative stress markers in animal studies.

Selank

3

SS-31

SS-31 is an aromatic cationic tetrapeptide that accumulates at the inner mitochondrial membrane and associates with cardiolipin. In lab systems, this interaction is linked to preserved cristae architecture, reduced cardiolipin oxidation and cytochrome c peroxidase activity, lower mitochondrial reactive oxygen species, and improved coupling of electron transport to ATP production under stress.

4

GHK-CU

In experimental systems, GHK-Cu acts as a high-affinity copper-binding complex that can stabilize and shuttle Cu²⁺ in a more controlled redox context, influencing copper-dependent enzymatic activity and signaling. Reported readouts include integrin and TGF-β–linked regulation, changes in MMP-2 and extracellular-matrix turnover, and shifts in antioxidant and inflammatory-response elements in cell and animal models.

We protect your purchases

Packaging
Seal

01

Safety seal

We make sure you are the first person to open the compound after its production. The seal means the compound is genuine, tested, and sterile.

02

Rigid packaging

Compounds of other peptide companies are delivered without boxes. Best case: a bubble wrap. We developed a box that keeps the vial protected at all times.

03

Batch number

The batch number is always accessible on the packaging and the vial. You can always cross-reference it with the data base of COAs on our website for the assurance.
