If you have looked around into purchasing SARMs, there are many different brands and vendors on the market offering the same supplements at different prices and in different ways e.g. capsules, powders, liquids.
The truth, however, is that a lot of vendors are lying about what they are selling, either deliberately or accidentally: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5820696/
While CMT Central is affiliated only with trusted vendors, I want to ensure this is a place of transparency and that all reputable vendors are listed, while vendors with a known history of poor supplement transparency are listed so that ultimately you can stay safe in a market with many options. Sometimes this may mean you are limited only to international shipping, but it is better to stay safe than cut corners and end up with a product that is either ineffective or dangerous. If a vendor is not on the list, a good rule is to stick with tried-and-(third-party)tested source until proven otherwise.
This list is not a guaranteed comprehensive list of all vendors, nor is it indicative of product quality. Always use your own judgement when selecting a vendor.
