I used and have a few of these test kits on hand. This is the one Palumbo "invented".
"LIMITATIONS:
The ROIDTEST system is a series of presumptive tests only. These tests check for the presence of specific steroids, but cannot determine quantity or purity. Likewise, ROIDTEST can identify many counterfeit products, but not all. It is also not designed to evaluate the safety of a substance. No drug use is 100% safe. Only laboratory techniques such as Gas Chromatography-Mass Spectrometry (GC-MS) and High-Performance Liquid Chromatography (HPLC) can provide a detailed analysis and understanding of all substances and quantities present in a particular sample."
Janos is about $120 I believe for the quantitative analysis. Plus, you'll have shipping cost to get the sample there as well, which will drive up the total cost. You name it, Janos will probably test it these days.
