>>14006017depends on the dose but most of the time it comes with insulin resistance and after long-term use, you will probably get type 2 diabetes.
plus it's too expensive so I'd recommend using GH secretagogue Ibutamoren AKA MK-677 which comes with the same risks plus some more because it is a research chemical literally not approved for human use.
plus because you seem like a teen because no one would use "after age of 18" I would not recommend taking any hormone before at least 21 unless it's doctor prescribed(even then your doctor might be a retard).
