Greetings Ladies

I would like to take Bird's Nest regularly. Anyone took before regularly? What is your experience? ?Any changes you have noticed?

Should I buy the bottled one or better to buy cleaned one and prepare myself?

It is relatively easy to buy bottled Birds nest. I understand from my friend that Bottled version manufacturers use waste bird's nest (While trimming they get some waste).Also difficult to verify the claim? Actual intake may be lower than what is mentioned on the bottle. In other way if I prepare myself, I have more control of my intake. What is the shelf life if we make ourselves with Raw Sugar?

Thank you
