I started off with one source's of GH here and felt it was alright. However I decided to go with 24 on my next purchase one reason being 120iu instead of 100 and about $50 cheaper. Been on gh for a total of 6 weeks, 4 of those being 24hr's @ 5iu ed. So far so good. All the sides that one would expect from legit gh. I've seen an increase in hair growth, nails, etc. The sleep is phenomenal. Very vivid and weird dreams, but nothing like Tren lol. Good US domestic option, T/A was 7 days.
