Chem/Super Serum is a classic, and it really does depend on being scientifically advanced. A classic example would be the Manhattan Project-esque US Super-Soldier program that produced Capt. America (many scientists, one serum) and a few others.
Also guys that either take pills or have machines that deliver triggered doses of chemical/drugs that get pumped into their system to let them do superhuman things- run faster, have a strength boost, etc. show up in Daredevil, Star Trek, RIFTS (the Juicers) and HERO. Big pharma that produces the former is clearly tech based, as is any company who can field an integrated chemical warrior system that doesn't kill the user due to stroke, heart attacks or the like.
Such programs also are often run in parallel with biotech or psi-research products, either to enhance or produce supers. In the TV series, John Doe, The Pheonix Group used pharmacology to enhance the powers of the clairvoyants they had gathered. The more drugs, the better the accuracy of the visions.
Larry Niven's psionics also did much the same- especially with the alien races. Nearly all Kzinti psions also used drugs- first to heighten their abilities, then to help them calm down.
