One and done.

Kendra Wilkinson revealed she recently started taking a weight-loss medication — but decided to stop after just one dose.

The former Playboy model, 39, told her Instagram followers Wednesday that she “started the weight loss shots” but quickly changed her mind.

“Only did one. Nevermind [sic]. Throwing away!!” she wrote on her Stories.

In a follow-up post, Wilkinson explained that the potential negative side effects drastically outweighed the benefits.

She explained her decision to forego weight loss shots in a recent post, stating that she is embracing a slight increase in weight while expressing contentment in her current state of happiness.

The celebrity, who is a mother to two children from her previous marriage, disclosed her concerns about the potential health risks associated with such medications, citing numerous distressing accounts of individuals experiencing adverse effects.

“People end up in ER. Surgeries. No thanks,” she added.

It is unclear which diabetes-turned-weight-loss drug — such as Wegovy, Mounjaro and Ozempic — Wilkinson used.

Although certain GLP-1 medications have received approval from the FDA, they have been linked to various side effects ranging from mild gastrointestinal issues to more severe complications like pancreatitis, kidney problems, and low blood pressure, as reported by the Cleveland Clinic.

The real estate agent began taking the weight-loss drug after facing backlash about her body from social media trolls.

In January, she clapped back at body-shaming haters after they commented on her curvy physique.

“Yes, I’ve gained weight. Yes, im aging. Yes, I’m not that girl i was before (playboy girl) 🤣,” she captioned a mirror selfie.

Despite the changes, Wilkinson said she is finally feeling “good and mentally healthy” for the first time in a while, noting that her life is “pretty balanced” and she is “working out and cooking a lot more.”

“For those of you hating on my new weight [and] 40 yr old face please know that I’m happy, healthy and at peace in life finally,” she continued. “Leave me alone and respect that I’m where I actually want to be finally all together.”

While the former model is “feeling amazing,” she jokingly admitted she does need to work on her “alcohol intake.”

“I hear you and that will be monitored better. Drinking too much is definitely drinking too much but you know what’s coming up in JUNE…. Shots. 😂,” she wrote, an apparent hint at her short-lived decision to take weight-loss medication.

Although Wilkinson went back on her decision to try one of the semaglutide variations, she still found other ways to stay fit, such as pole dancing classes, tennis and weight lifting.

However, she admitted last month that she has a hard time sharing on social media due to the mean comments.

“God, it takes me a second to post photos now. Wondering how much hate and bullying I’ll get for my new body and age but I’m going to post this today and feel proud of myself,” she wrote on Instagram. “I have overcome so much in life and deserve to celebrate myself and my new attitude towards life.

“If people don’t like me or this or think I’m bigger or i can’t turn men on anymore GOOD then there’s the door.”
