Well worth it. Dosage...As much as you can afford. Currently I use Serostim at 6iu per day. Been on GH nonstop for 3 years. I don't intend on ever stopping. Sleep is amazing, recovery time greatly reduced, impossible to get fat with it, skin, nails, everything looks better, and younger. I'm 40, most guess my age as upper 20's. It gives dense, thick look. I've used slin with it preworkout, and while good for size, I won't use it again. I'm 5'8 and 245 right now dieting hard. The pumps with GH are amazing, and you don't need nearly as much gear with it. Everything works better, more efficient. Downside is lethargy, and insulin resistance. Favorites are Humatrope, Nutropin AQ, and Serostim. All directly from pharmacy. I also use T4/T3 combo with it, as thyroid is low without it. Once you're over 35, you'll really see the benefits of GH. Forgot to mention, immune system is greatly enhanced with it. Never get sick, or have a cold with it. I've felt like I was getting a cold, and the symptoms are gone in 1-2 days. I'll drop the dose to 3 iu per day at times, and still very effective. No lethargy either.
