Known effects from testing and reports
- Meo-EST is a potent molecule which creates intense “crush” feelings (especially in high doses). This crush feeling is not quite as emotional as androstadienone, but more physical – you and people exposed might get the excited feeling in your gut, commonly known as “butterflies”. It is an excellent addition to attractionmixes and using as a buffer.
- People will feel a desire to be “closer” physically. They will be more inclined to hug, touch, and in some cases escalate things sexually. This effect was noted by several women, however I have noticed similar effects when combined with more aggressive mixes.
- Meo-EST seems to act as a social dis-inhibitor, which allows people to feel more comfortable in your presence. They will feel like they can express themselves around you without judgement or social backlash.
- People will treat you with more affection, and feel a sense of connection with you. It seems to “harmonize” social groups, and make you the center of attention but also create a peaceful, energizing, and more socially “open” feeling among everyone nearby.
- Behaves erratically for some people – it seems to be energizing for certain people, but others report sedation. At doses 30-80mcgs+, users report impaired attention and concentration, decreased motor coordination, forgetfulness, and unusually vivid dreams.
- Very early reports suggested that this pheromone also made people feel like cleaning up their immediate environments. While I haven’t noticed this myself, it has been noted several times over the years on various pheromone community boards.
- Some people believe methoxyestratetraenone can cause cancer as it is found in breasts for women suffering from it. However, these claims are unfounded as there is no evidence to prove this is true. Some men however avoid spraying it on skin to avoid any potential issues. Some people find that it is easily absorbed through skin and put weight on more easily.
