Hi All. Thanks for those who gave me suggestions on choosing the right product. I thought it might be useful to share my experience here after my first try of Alfa Donna.

I ordered a 5ml sampler and got it last Thursday. The scent I picked was Romantic Flowers. So I tried it 2 times so far, 1 time at home, 1 time go shopping.

Scent: It is good, but I think when I order the regular size next time, I will try tangerine (if I remember the name correctly). I think the Romantic Flowers is a bit strong for me.... just personal preference. After 2 hours, the scent becomes very light. You can still smell it , but very light (which I really like).

Bottle: Somehow it leaks a bit whenever I spray. Not a big problem.

So the 1st time I put 3 sprays, 2nd time I put 4 sprays.

The reaction I got from my hubby: (I didn't tell him it has pheromones or copulins... I told him I bought some perfume samples.)
- nothing particular
- he thinks I smell really good

The reaction I got from other people:
- I haven't seen anything unusual in the meantime. People seem to react like usual.

Self-effects:
- Nothing particular, but I did experience a very minor headache during the 2nd time. (not sure if it is related to the perfume or not).

Conclusion:
- Need a few more try to see the results (will try again tomorrow because I will have a large meeting with stakeholders... good place to test it!)
- Romantic Flower doesn't suit me the best
- No matter if I get reaction from people or not, I still want to order the tangerine scent in the near future (waiting for Valentine's Day discount!!!)

P.S. I should also mention this. I also ordered a few samples from Love Potion. This is totally a personal preference, so far I tried 2 samples from Love Potion and Alfa Donna, none of them gave me any unusual reactions from people. It could be because the amount I put were not enough. But in terms of smell, hubby and I agree that AD suits me better. And in terms of customer service, both companies are great. No complaints at all!
