The only thing is that not anyone with a chemistry / biochemistry / chemical synthesis degree will do,
you need someone who
already has experience in synthesizing steroids, and they're in such high demand that they're paid 6-figures.
IMO start by being THE BEST reseller.
Start by remailing raws to top accredited labs like Simec or Lab4tox,
and get a money back guarantee if raws come lower than 95% pure.
Get lab deals so they can begin testing other steroids and esters,
the first new test will be a bit expensive as they need to buy the new reference standards, and do trial runs, but it gets cheaper for the next tests.
After some tests, and rejecting some batches due to low quality, you can easily become THE wholesaler
so sources begin buying from you wholesale because of your outstanding quality.
After a while you can start doing HPLC testing yourself (hiring HPLC technicians)
this thread can get you started on HPLC testing
