Thoms,
Thanks for replying!
Yes vials are from the same source.
The reason for the different shapes lie in the fact that the vials contain true Nandrolone, I think (judging by it's side effects), but the supplier skims off the real vials by some 0.3 ml and uses it to fill new vials (i.e. the vial with the rounded 'shoulders').
The vials should contain 2 ml. Each one however contains only 1.7 mls. I'm p*ssed o'ed about this, as you'll understand, but it's not my main concern right now.
For the moment I just want to know if it really is Nandrolone or some other cheap knock off. The side effects are mild, no facial hair or whatever, great strength increase, better libido (hurray!!). So it feels like Nandrolone.... or have I been fooled?
