“Advanced Chemistry” is a sex farce, which is not to be confused with “romantic comedy” as a genre, although that distinction has rarely been applied to a more “PG” picture.

Clunky, timid and tame-right-to-the-edge-of-chaste, it’s a dull dive into biochemistry, “monogamous attraction” via hypodermic needle, air guitar as an art form and “full facial nudity.”

That’s as romantic and as sexy as this one relationship — with a germophobe and central to the plot — gets.

Samba Schutte and Kiaran Deol play chemistry students under the tutelage of an impatiently lceherous mentor (Iqbal Theba).

Allen (Schutte) is a hapless doormat when it comes to love. He’s always losing that potential bar pick-up to his aggressive, lesbian bestie. The ladies — even the straight ones — can’t get enough of Marsha, Marsha Marsha (Chaunte Wayans).

Allen and Lisa (Deol) are competing for that one spot to be funded in their university’s program. He’s working on “Bondo,” a drug that will encourage chemical fidelity to a loved one the way voles practice monogamy. Lisa’s “Lixi” promises better orgasms in women.

As Marsha is “a cheater from a long line of cheaters,” she begs to be a human test subject for Bondo. That’s how Allen tumbles into a world of misdirected needles creating irresistible attractions — few of which he has any interest in.

But Lisa might be different, a co-conspirator in his illegal “test” case and a germophobe repelled by the idea of physical contact, much less physical attraction.

Every so often, as this or that person in the broader plot gets injected, on purpose or accidentally, they have to hide Allen’s actions from wacky, over-committed Safety Officer Nancy (T’Keyah Crystal Keymáh), who pops up like zealous “safety” Nazi.

Director Etana Jacobson keeps the tone light and screwy. The players do their utmost to take things over the top. But the pacing is flat, few jokes come close to landing and the cast’s “utmost” just doesn’t get us there.

“Advanced Chemistry” has problems with the basics.
