After reading about Androstadienone, I'm going to hope I'm not one of those who get the depression effects. However, I don't know which vendor to buy it from. I will be making a purchase from PheromoneXS and LAL soon for some of their product line. I see they both sell it in oil form but LAL is much more expensive.

LAL
PXS (not sure why it's re-directing to the thumbnail page)

How come there's a big difference in price? LAL's 20mcg per drop is $87.97 , while PXS is $41. Should it be the same in both vendors since it's a single molecule or does "you get what you pay for" applies here?

So far, I've found Pheromone Treasures' Androstadienone to be the best value for money (approx. 50mcg/ml). You can choose carriers, moreover.

Others have reported differences in various vendors' Androstadienone . Some are smoother, while others are raw and cause more of the depression effect.

Only way to know is to try.

There is a difference between suppliers/manufacturers.

I bought some cheap but found that it was kinda harsh towards women and guys just wouldnt want to be around you.
Then got some from a different manufacturer and it made a big difference.
Even better than LAL which was reported to be the best.
So try to get some samples.

Pheroman,

Whose the manufacturer with the A-1 that you think is better than LAL's?

I actually dont know.
I got it as a gift sent to me saying "try this Androstadienone out its really good". No idea where he got it from.
Its very strong in smell, very concentrated and works great at small amounts.
I threw out the remainder of my other Androstadienone after the first use.

FTR Pago knows much more than me about different types of Androstadienone and where they come from, he is probably the best person to ask.

Pheroman, you said you bought some cheap Androstadienone . Which vendor was it from? Or knowing if it's from PXS would be as helpful. I can't spend $87 on a single product (LAL's Androstadienone ) as I want to buy few products from each company so I'm already spending a lot of money.

You answered your own question in the OP re cheap Androstadienone .
Is there a difference? Yes.
I highly doubt its from PXS.
I do know Chris from Alpha Dreams supplies a lot of vendors and it ain't his.
He also seems to have changed something in his Androstadienone over the years.
LAL seems to have a different Androstadienone .
I'm not sure about True Pheromones or LPMP

Again the only guy I think would have tried all of them just for fun is Pagodeiro and maybe Therry.
All I want is a light switch, I have no interest or care which electron are jumping whatever orbits.

Just an update, I've decided to go with LAL but i bought the 10mcg per drop instead of 20mcg. A price of $48 instead of $88 is more affordable and reasonable to me. I will simply increase the number of drops when I want to go higher and applying 30mcg is easier with a 10mcg/drop than 20mcg
