Not any reputable sources, no. Plenty of Boosters out there, but if it was that easy - everyone wouldnt be on a TRT plan. If your regular doctor wont do it, find an independent doctor. They'll test you, then when they see you arent already taking anything - they'll prescribe you whatever you want. Some people prefer the shots every week, two weeks, or a month - but I felt like I had mood swings with it. Like my body soaked all of it in already for example, or it would get too much on the same day as the shot and I would feel like I was getting ready to go Super Saiyan at any moment. Versus what I use now, which is the Androgel, and you can get a 90+ day supply of that for ~120 bucks with GoodRX. Androgel is applied daily, so I feel like its much more regulated. Insurance may cover it, but since I own my business - my deductible is high as giraffe's pussy.
