a friend bought some gear and told his supplier that he was feeling sick after injecting. Supplier claimed it was test flu. sounds like bull to me. Someone else who makes his own tren told him to put the bottles in the oven at 250 degrees for 45 minutes with a insulin syringe in the rubber, also pulling out the plastic piece used to push gear through. This is suppose to draw out any excess alcohol and bacteria. the reason for my post is that i bought some of the same gear and have not used it. i would try this if it works. i have no education on this and am seeking answer from someone who knows. Or any other suggestion besides dumping the product.
