I’ve tried a few different brands over the years, but I’ve found that the Spectros kits are probably the most reliable for consistent results without the weird water retention you get from lower-grade stuff. When I’m looking to restock my supply, I always stick with this from a domestic source because the last thing I want is to wait three weeks for a package to cross an ocean and hope it wasn't sitting in a hot warehouse the whole time. Having that 140 IU kit show up at my door in a few days is a massive relief and ensures the potency is exactly where it needs to be. My best tip is to start with a very low dose, maybe just two units a day, and run it for a long period rather than trying to blast it, because the benefits really start to compound after the third or fourth month.
