Sweet Tip for Steroids:

1. Remember good steroid powders like Winstrol (Stanazolol) or Dianabol (Danabol) must be micronized and pure. No other particles should be contained. If you find many particles that doesn't dissolve when you filter the solution, it means the powder has been mixed with other un-related stuff and those can become part of the weight of the powder, making the real ingredient less than it should be.

2. Can place a small order to have a trial before bulk order. You can make some simple tests such as making powders into solution, filter it and check if there is any un-dissolved particles or heat the powders to check its melting point and compare it to the standard. Melting point is an unique property of a certain chemical. If the MP meets with the standard or not can tell if the chemical is real or not. The second way is to find a professional lab and let them make a detailed test. You will get a detailed report after the test is done.
