Paraguay is THE LAND of fake products.
You can find from PS4 to Bayer aspirin.
The Landerland brand is manufactured them, and they provide the most quantity of roids to Brazil, Argentina and Uruguay (is real underdosed shit)
You shouldn't be surprised that Brithis Dragon is still "manufactured" there.
The best choice is buy raw and do your own stuff. If you can't, go and ask the source.

I hope what you used was legit.
