The science

How SYNAPSE Blend works, and what the research shows.

How it works

Semax is studied for attention and memory through a brain growth factor; Selank for calm through the brain's own calming signal.

MOTS-c is studied for switching on the cell's energy sensor.

Tesamorelin prompts the pituitary gland to release growth hormone overnight.

Clinical evidence
  • No clinical trial has studied this exact combination.

  • The evidence is for each peptide on its own, and your physician weighs that when deciding whether the blend fits you.
