So far Tiger Mask W has the testosterone department covered but I am still open to more as well.

I don't know what you mean by Twin Peaks- esque. Here are my suggestions.

Comedy:

Baka and Test
City Hunter
Cromartie High School
Dr. Slump (A funny classic)
Excel Saga
FLCL
Ghost Stories (Dub only. Just watch it for the dub)
Golden Boy
Inukami
Kyō Kara Ore Wa!!
Magical Shopping Arcade Abenobashi
Panty & Stocking with Garterbelt
Project A-Ko
Osomatsu-san
Ultimate Otaku Teacher

Slice of Life:

Azumanga Daioh
Bunny Drop
Genshiken
His and Her Circumstances
Nichijou
Silver Spoon
Slow Step

Testosterone Fueled Action (These anime have action that will fill up your testosterone levels by over 8000 )

Ashita No Joe (Great classic)
Baki the Grappler (2001 TV series)
Battle Royal High School (Not to be confused with Battle Royale)
Berserk (The 1997 TV series. You can also watch the movies if you want)
Cyber City Oedo 808
Fist of the North Star (80's TV series and Legend of the Dark King are both awesome)
God Eater
Golgo 13 (The 2008 TV series. The movies are cool too)
Gurren Lagann
JoJo's Bizarre Adventure (The TV series)
Kaiji: Ultimate Survivor
Kinnikuman
Mazinkaiser SKL
Mobile Fighter G Gundam
New Getter Robo
Ninja Scroll (The movie)
Riding Bean
Sakigake!! Otokojuku
Sengoku Basara

Stuff that is not derived from a light novel (I guess you mean anime that are not based on light novels):

Another
Big O
Bubblegum Crisis (The original OVA series or the 2040 TV series. Both are good)
Detonator Orgun
Escaflowne
Jin-Roh: The Wolf Brigade
Martian Successor Nadesico
Serial Experiments Lain
Tiger & Bunny
Witch Hunter Robin
Wolf's Rain
Xam'd: Lost Memories
