I have not had any issues with t/a from gbn on anything yet. I recently ordered 2 kalpa test e and had a chance to run them to be able to give an honest review. It's exactly what they say. It's pharma grade from a different country. Quality is great and that has been consistent as well with gbn.
Libido was through the roof on just 1cc a week. I didn't get a chance to pull bloods but I wish I could've seen my numbers
