A fitness influencer is selling bottles of her own sweat at £40 a pop and claims to have shipped off 100 batches so far.
Karol Rosalin was surprised when one of her 1.6m Instagram followers sent an unusual request.
The fan asked if the 27-year-old would consider gifting them a vial of her “post-workout body scent”.

The influencer mulled it over for a few days and eventually decided she had nothing to lose, but money to gain.

The venture was such a success that she’s since filled 99 more bottles.
“The follower asked me for a bottle of my ‘post-workout body scent”, she told Need To Know.
“At first, I thought it was a joke, but when I saw how detailed the request was, I realised it was genuine.

In the past, followers have asked me to rate their physiques, requested to watch me cook or for me to watch them work out.
“It is fair to say I receive specific requests – but I’ve never had anything like this one.
“Of course, I thought it was strange at first.
“But then I thought, why not?

“He was a long-time follower, very polite and really appreciated my content.
“He asked for real sweat, collected after workouts, and even specified different areas: back, legs and abs.”
After she shipped off the first batch, Karol shared the experience to her Instagram Stories – and more requests came rushing in.

She said: “I’ve already sold over 100 units.
“It’s the most intimate part of my post-workout routine.
“And I felt it was fair to turn it into a product for those who truly value the effort.”
The fitness influencer, who also shares saucy snaps online, believes this could be a new cash cow.

Karol, from Brazil, added: “Rather than simply selling images, I position myself as the embodiment of what many followers consider the perfect woman.
“Strong, disciplined, sensual and approachable.
“I sell what they dream about, but I also deliver real sweat.

“It’s real effort, real training.
“It’s not just a pose — it’s consistency.”
