Six UK and UK-shipping research peptide retailers ranked on Tesamorelin availability, HPLC purity, Certificate of Analysis transparency, and UK delivery speed. Tesamorelin is an FDA-approved medicine in the US (Egrifta, for HIV-associated lipodystrophy) but has no UK marketing authorisation. UK retailers sell as research use only.

Editorial summary, May 2026.
Why Tesamorelin is more expensive
Tesamorelin is a 44-amino-acid stabilised GHRH analogue, longer and more complex to synthesise than Sermorelin (29 aa) or Ipamorelin (5 aa). UK retailer pricing is roughly 2 to 3 times Sermorelin per equivalent vial size.
