Sure, here we go:

package main

import (
	"fmt"

	"github.com/wangluozhe/requests"
	"github.com/wangluozhe/requests/url"
)

func checkErr(err error) {
	if err != nil {
		panic(err)
	}
}

func main() {

	req := url.NewRequest()
	headers := url.NewHeaders()
	headers.Set("User-Agent", "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/86.0.4240.198 Safari/537.36")
	req.Headers = headers
	req.Ja3 = "771,4865-4866-4867-49195-49199-49196-49200-52393-52392-49171-49172-156-157-47-53,0-23-65281-10-11-35-16-5-13-18-51-45-43-27-21,29-23-24,0"
	r, err := requests.Get("https://www.costco.com.mx/", req)
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println(r.Text)

}

Thx in advance!
