Testosterone Spike on Day 7?

So there is this myth or fact going around most of the internet that if you don’t fap or masturbate for 7 days there will be a testosterone spike on the 7th day. After looking this up more and researching this on a more scientific side, apparently there has only been one study on this and it was done in certain circumstances. I’m not doing nofap because of this 7 day spike, but I am trying to explore the effects of nofap and I’m wondering if anyone has any experience or has seen any affects from either 7 days of nofap or this spike at all?
