for sure, thats not a great sign.
does give a small insight into whats going on at the lab, the conditions at the lab, the shortcuts being taken or all of the above.
OR..
it could even be a rival lab trying to stop the new labs progression.
such a crooked world sadly.. all we want is a legit, honest decent supplier, but theres so much unscrupolous behavious going on that it becomes difficult to navigate around.
most of the sources that have had fairly decent feedback over a steady amount of time, 5 year plus.. are more than likely sticking to some simple basic rules that will ensure they stay around for awhile.
1 - dont under dosage
2 - no shortcuts.. sterility must remain number 1
3 - if occasionally you get it wrong.. and through no fault of your own, you may do so, you do your absolute best to put it right. to ensure it doesnt happen again.
4 - never let the lure of money take you away from your high standing morals.
