Welcome! Not all of us crusty oldsters resent the newbs. I would say most of us don't, even. But we are tired, and very protective of this space, and the waves of new people who need help just keep coming. I understand why; this space saved my life. But I've seen some of the places that helped me the most disappear under the weight of unmet need and greed, so I'm a little cautious.
I spent less than 6 weeks on branded, paying out of pocket, then bought a few vials from Focal Dose- a reputable domestic that since ceased and desisted- while I figured out China. I HIGHLY recommend a reputable domestic for a couple or few months while figuring things out. It is much cheaper than jumping into a sketchy "group buy" and getting shafted with cheap low quality product, or worse.
"Group Buy" has become a pretty much meaningless term now, imo. It used to mean a group of people pooling their resources to get a better deal and leverage better terms and protection for the group. Now, it's more often just a buzzy phrase, an MLM, and true group buys are rare. The good ones do not recruit or advertise, period. Watch and wait. We are on these meds for life. It's worth finding the right ones.
