Tren can greatly reduce how GH is converted into IGF-1. Two people can take the same GH and dose and have varying IGF-1 levels. The conversion in the liver has a ton of variables. The GH hormone level in the blood should be the same given same blood volume.....GH serum is more accurate. IGF-1 gives you an idea how effective your liver is converting the GH into IGF-1. Both values are good to know. GH serum is good for determining product quality.
