Here is more general info and I only post this so you mates know what is involved in AAS testing and perhaps to enable Meso members to better understand why UGLs selling bunk often escape detection by AAS users for prolonged periods.
Oh there is another important factor I overlooked which is, does the facility have ALL the equipment required to perform the tests desired?
No doubt the single most important device is an HPLC with SEVERAL columns (Vitamin D column works great for many yet not all AAS) Excluding the expertise of the chemist, and I do mean a PHD level chemist, and the availability of RESEARCH standards, the next most important factor is the COLUMN itself. These puppies are NOT cheap ($600 - $1500) and most are designed to better evaluate specific compound classes.
For example these classes of AAS are best assayed using DIFFERENT columns
1) 19-Nor Deca, Bolo, Tren
2) Ester = Var, A-drol,
3) Nitrile = Stanozolol
4) Halogenated = Turnbol,
5) Multi Hydroxy groups = Test, Dbol, Master
The lab I use carries four of these five columns at a cost of $3800. Did someone say so what Jim
Well the problem is only 3 of the 4 columns are capable of multi-compound analyses and as such are limited to the evaluation of a few AAS.
Now if your a business and are aware of the limited demand, now understanding the startup cost will approximate 4K, most wise businessmen will say, NOT to the prospect of testing AAS.!
Next is a MS and there are SEVERAL types, each having their specific benefits, areas of expertise, pre-procedural qualifications, means of ionizing the sample compound, MW range limits of the sample compound etc.
Finally the optimal compromise is a LC/MS where the specificity of MS is combined with the sensitivity of HPLC.
But remember for optimal accuracy and reproducibility ALL of these tests require the use of STANDARDS for comparison purposes. So sure you will see labs post a MS of their Test-e BUT what you should also see in the backround is the MS of a RESEARCH grade standard for comparison purposes.
Bc in the absence of that standard the ONLY factor that may be determined with utmost certainty is the sample compounds Molecular Weight!
Thus the take home point in this post is, STANDARDS are the STANDARD which all labs use to confirm or refute any compounds presence or absence and without them the test is INCONCLUSIVE at best.
