Good day gentleman.
I've been on green tops for 2 months untill my supplier couldn't get them anymore. I was planning on switching to blue tops but according to my supplier they changed into yellow tops but are exactly the same. I've been using these yellows for 1 month now.
I've been doing business with him for a long time and I trust him. But it worries me that these yellow tops don't have a vacuum seal. The syringe doesn't automaticly empty itself into the vial. As for the usual side effects, i'm not experiencing many. My hands are a little numb in the morning and I feel more tired as usual but that's about it.
Is anyone here using these yellow caps? What was your experience with them?
Thanks.
PS, English is not my first language but I hope I made myself understandable.
