I'm almost positive no compounding pharmacies compound GH in the U.S.
503b compounding pharmacies are the only compounding pharmacies allowed to mass produce medications without a script on hand. All other compounding pharmacies must compound the medication on a "made-to-order" basis (e.g. they need a script on hand, and can't just mass produce the medication ahead of time and then wait for orders to trickle in).
Even the largest 503b compounders don't produce GH. Some produce peptides, but all the compounding pharmacies that I know that carry GH only carry GH produced by big pharma.
