Enrich for

[ayag]

Hi,
I've come across the word enrich followed by for ("It’s all been done before, every snickering bit of it, and not just by powerful “risk-taking” alpha men who may or may not be enriched for the hormone testosterone.) in several articles, especially online, which has left me whether the usage is correct, & if it is, what does the preposition indicate.
Regards,

It is not correct.

"by" would be more appropriate. However, enriched is a bit weird here too. Was it written by a native of standard English?

Hi,
Thank you for the response.
I think so too, but there are just too many similar instances. The example quoted is from The New york Times.
