There is a copy/paste text below from a Canadian bodybuilding board that explains this in detail:
No independent lab has verified if the kits are accurate or not.
Now here is the main issue with the LabMax/Roidtest kits. These kits fail to take in account the other numerous ingredients and/or chemicals that go into any steroid, whether in tablet or injectable form. For example, when a 20mg tablet of Proviron is pressed, there's far more included in that tablet than just 20mg of Proviron. We have binders, fillers, dyes, lubricants, and a variety of other substances. Another good example. Consider something like Clenbuterol for example that is dosed in MICROmiligrams. More than 95% of the tablet will contain everything but the active ingredient. You’re trying to tell me that these kits will disregard 95% of the ingredients (Dyes, binders, etc) in there, and based on the other 5% (Which is actually Clenbuterol) identify the compound correctly? Give me a break.
If these kit were made to test the raw powder prior to making finished products I could perhaps MAYBE believe in it...but claiming to identify what a compound is once it has been pressed into a tablet/capsule is just none-sense. Even then, the owners have failed to conduct any third party testing or any scientific proof that these kits are even capable of identifying different compounds based on just the raw material.
To add to that, LabMax and Roidtest have been called out on numerous forums across the internet and have failed to offer any sort of scientific backing or evidence that prove their tests do anything other than pump out some random colour of the rainbow on any given day. They've had ample opportunity to shut everyone up and prove the doubters (myself included) wrong, yet they never have. On countless mainstream forums their sponsorship/advertising was pulled because of that reason as well.
Sending products to a creditable facility with HPLC testing is the correct and accurate way to test products.
