Hi everybody,
When it comes to injecting external substances into your body, you realize that you need to take some precautions if you don't want it to become a russian roulette shot.
The basic precautions could be :
1. Check your source and ensure they are selling quality gear :
The source is referenced in the laboratory website.
Exeprienced users tell you they are good to go.
2. Check the authenticy of your products :
Some laboratory website let you check the serial number of the product.
Submit photos on forums et have a feedback from users.
what else ?
take a very low first dose to ensure product is not toxic ? what amount ?
having a friend testing it for you ? :-)
