Another way you can be retry sure is if your source uses the HGH and is a mega exp user. He orders a bit before everyone needs to reup, and goes on it himself. He knows real HGH when he uses it, so by the time it gets to me there is nearly no question. His supplier knows this too so it tends to help insure the product is good,
Whats crazy is price is not reflective of legitimacy. Kind of makes sense, if you fake stuff, or underdose, you are about $ at all cost. Of course youll charge away. Best stuff I know of is way less then the typical rate. But it's just finding a good kniwledgabke source who cares, and him finding a producer who prefers steady quiet exchange of legit prod for prices most folks would be dubious of. But it works if all sides see it the same way.
All I can say is it's about the right producer and the right guy, price and quality follow. Best HGH Ive had in forever is the best priced by a country mile. It's just about connections and honesty and relationships, but more above the customer at the producers and supplier level. Get a producer and source who both have integrity, and they find they can do best giving the best price possibly at the best quality. Leads to more customers... BBs but, a ton are anti-aging wives and friends, bc it real and now actually affordable.
But I think mainstream, prices won't budge and quality will always fluctuate. To many players with no integrity involved. Some lucky closed systems, top to bottom, are making it work. But they are just that, closed.
