The best cycle I ever did was a stack of Mexican vet gear. Reforvit, Testosterona 200 and Norandren 50. I put on over 30 lbs of muscle in a month and was insanely strong.
But again this was back in the 1990s. Perhaps the quality of these products has diminished and there are indeed a ton of fakes being produced which wasn't the case before.
Regarding the Cabergolina being fake, I suppose anything is possible. If it is fake, the fraudsters did an excellant job because I can't observe any anomalies. Everything looks perfect, from the packaging, the bottles and the pills themselves which are very thick and difficult to break apart.
