Hey bro, good question, the truth is, for a peptide company in the US, cold dms are one of the least effective strategies these days, people are already fed up with spam, and conversion rates are incredibly low, there are much smarter ways to connect with real affiliates.
The most effective method I've seen is to set up a well-structured affiliate program and promote it in the right places, there are brands in the sector that have programs with 10% commissions and 60-day cookies, the key is to make the program attractive with competitive commissions, ready-made promotional materials, and a reliable tracking system, then you promote that program in specialized affiliate directories, not on generic social media, that's where serious affiliates go to look for opportunities.
Another strategy that's yielding amazing results is product seeding with micro-influencers in the health and wellness niche, tou send free samples to content creators who already talk about health, fitness, or biohacking, if the product is good, they'll talk about it on their own, and their followers will become interested, many of these interested followers end up becoming affiliates because they already know and trust the product.
