How to find this offer

Hi guys, I'm sorry if I put this on the wrong place,
.
I just saw this offer popping up and would like to know which affiliation network is having it
https://buytestomaxperformance.com/promo/dlx/

I will be pleased if someone can show me a trick or a tool how to find which affiliation network has this offer?

Thanks in advance

Can't find because you shared the lander link. If you would have shared the complete link (with tracking macros), I might have told you the network name.
However if you're looking for similar offers, I can suggest you tons of them. Let me know your traffic source and geo and I'll pm you the list along with their approval rates.
Thanks
