You are making logical sense here, but as one who used the last of the French parabalon and then used supposed decent tren from British Dragon (10-12 years ago), then tren from other UGLs a few years ago (not as good as BD used to be) there is no comparison with the original stuff.
Which means it is all underdosed. You would go mental taking 2-3 parabalon a week, now I know of shitty looking gym rats taking 1gm a week and my mind boggles.
I see it all the time though - people get more of a kick from 1 testovis (100mg test prop) than they do from 300mg of ugl test prop.
UGL steroids are a mug's game now IMHO. And the pros have no clue what they are taking, when I hear about super secret sources of the pros I piss myself laughing. They get the same shit from the same dealers as the rest of the gym world.
The best route if in N.America is to get a script from a friendly doc and find an even friendlier compounding pharmacist. I've seen wonders happen on one cap of 20mgs anavar, 10mgs turinabol and 5mgs winstrol daily (from a pharmacist).
Some thoughts: some UGL gear has been analyzed by government labs in different countries after seizures and it has not all been underdosed. There's also little reason for a UGL to underdose. One Canadian guy who used to post here, forget his name Pierre something, said all the UGL's actually overdose due to the competitive nature of the market. Not saying there's no underdosing but if you can get the raws through customs in the first place why underdose? The Chinese raw material may be underdosed but here again, why would it be heavily underdosed? I believe Mawse here who commented on the Chinese raw purity.
Regarding the compounding pharmacists working for wellness clinics, I bet it's all smuggled UG powder out of China too, because the whole operation isn't completely legit in the first place. This has been verified in newspaper articles through the years too. Compounding pharmacists putting together injectables with Masteron, Tren, Dianabol etc, does it sound legit and completely legal?
How is the Turinabol you mention legally imported into North America?I would think this stuff is basically the same as any UGL gear, perhaps with better brewing facilities.
Regarding going mental on tren. Yes it does make you mental, I can feel the negative change after one shot. But if you can handle a little chances are you can handle a lot after a while. And if you can't, just smoke a lot of weed and pop the benzos like a lot do.

I agree that pros are using the same hit as the average gym rat in most cases. But look at the Olympia guys, does it look like they are on fake steroids?
