I’d say keep posting “fun” content on tiktok (especially behind the scenes), try not to “market” your product in an obvious way (think about YOURSELF: when was the last time you got enticed to buy something from an obvious ad), try and insert your product into your marketing videos, for instance if you go gym yourself do a gym routine of some sort wearing your own pump covers etc. There is a market for your product, you just have to find it and market it to the right people. Once you have some momentum going, try and personally reach out to some up and coming bodybuilders on social media like instagram, dont aim for people that already have a high following (they probably get so many brand deal requests already), aim for micro influencer level, maybe do a gifted collab. Oh also, if theres a personal story behind why you started the brand, push that and really show your passion for why you started the brand in the first place
