All the vendors I recommend have been around for years and have earned a good reputation in the community. I ordered and used products from these websites myself and can vouch for the quality of their products (at least for the time I ordered from them). For a vendor to be included, they must meet the following criteria:
Readily available 3rd party lab testing results (for research chemicals companies)
Excellent customer service and support
Positive reviews within the SARMs/Self Improvement community (On Reddit & Forums)
Disclosure: I get a (tiny) commission if you decide to make a purchase here, at no expense to you, in fact, you’ll get a sizable discount most of the time. I truly believe in these companies and their products. If you are going to get SARMs, or reaserch chemicals they are your safest bet.
