How it works

The idea is that these short peptides switch genes on or off in a specific organ. That theory has not been confirmed in independent studies.

What people use it for

  • Supporting the prostate
  • General "anti-ageing" and longevity

What the research shows

  • Most studies come from one research group in St Petersburg, Russia.
  • The evidence is mainly from cell and animal studies, plus small human studies.
  • There are no large, independent clinical trials.

Side effects & risks

  • Long-term safety in humans is unknown.
  • Products bought online may not contain what the label says.
  • Injection carries a risk of infection if not done with sterile equipment.

Is it legal?

Not an approved medicine in the EU, UK or US. In most countries it is illegal to sell it for use in people. Products labelled "research use only" are not checked for quality or purity. Some related products are sold as dietary supplements in Russia.

Storage & safe handling

  • Mix with bacteriostatic water: let it run slowly down the inside of the vial and swirl gently — never shake.
  • Store the mixed vial in the fridge and follow the use-by period on the label.
  • Wipe the vial top with alcohol and use a new sterile needle and syringe every time.
  • Rotate injection sites so the same spot is not used again and again.
  • Put used needles in a sharps container, not the household bin.
  • Get medical help for redness that spreads, fever, swelling or trouble breathing.
