Science.bio has closed: what happened and where to compare prices

science.bio · Updated 20 October 2026

Science.bio sold nootropics, peptides and SARMs online. Between 7 January and 8 February 2026 its homepage changed to say it had permanently closed.

Its notice says the company decided to permanently close and stop selling research products. It gives no reason. It warns that anyone claiming to be Science.bio, a successor, or to sell its products is not affiliated with the company. The notice was still up in October 2026.
