Check Function without execute it – PHP

i’m training SOLID/Architectures and trying to make an INSERT on my code, but its insert four times on DB. There’s any error on my logic? I’m following Repositories/Service Pattern.

i think my service is executing two times, but i cant find the reason.

Repositorie Code

    public function inserirEstoque($dadosPost)
    {

        if (empty($dadosPost)) {
            return false;
        } 
        
        $pdo = $this->dbConnection->conectar();
        $sql = $pdo->prepare('INSERT INTO estoque (nomeProduto, descriptions, price, quantity)
                                 VALUES (:nome, :descriptions, :price, :quantity)');
        $sql->bindValue(':nome', $dadosPost['nomeProduto']);
        $sql->bindValue(':descriptions', $dadosPost['descriptions']);
        $sql->bindValue(':price', $dadosPost['price']);
        $sql->bindValue(':quantity', $dadosPost['quantity']);

        $res = $sql->execute();

        if($res == false)
        {
            return false;
        } 

        return $res;
    }

Service

public function insertEstoque()
    {
        
        $db = new MySQL();
        $insert = new EstoqueRepositories($db);

    
        if(!empty($insert->inserirEstoque($_POST))){
            return $insert->inserirEstoque($_POST);
        } else {
            return false;
        }
    }

Controller

  public function insert()
    {
         $insert = new EstoqueService();
         $insert->insertEstoque();
         header('Location: ../../index.php');
    }
