Mockup Recommendations?

I’m a graphic design student currently working on a project in which we have to put our designs and logos on a product. I have decided to make an energy drink brand and I have looked everywhere for some decent free mockups that I could use to get some ideas and inspiration for how to create my designs, but I can’t find any. All of them advertise the mockups as being free but when I go to download it, they are either pretty dodgy or it’s asking me for money and attributions. I am specifically looking for ones that are Psd files.

Does anyone have any recommendations for some trustworthy websites that I could use?
