Create a function getAttributeAdminLabel() in your block and call this on page where you want.
$storeId = 1; //add you store id
$attribute_option_id = Mage::getResourceModel('catalog/product')->getAttributeRawValue($product_id, 'my_attribute', $storeId);
$product = Mage::getModel('catalog/product')
->setStoreId($storeId)
->setData('my_attribute', $attribute_option_id);
echo $attributeText = $this->getAttributeAdminLabel('my_attribute', $product);
function getAttributeAdminLabel($attributeCode, $product) {
$entityType = Mage::getModel('eav/config')->getEntityType('catalog_product');
$attributeModel = Mage::getModel('eav/entity_attribute')->loadByCode($entityType, $attributeCode);
$_collection = Mage::getResourceModel('eav/entity_attribute_option_collection')
->setAttributeFilter($attributeModel->getId())
->setStoreFilter(0)
->load();
foreach ($_collection->toOptionArray() as $_cur_option) {
if ($_cur_option['value'] == $product->getMyAttribute()) {
return $_cur_option['label'];
}
}
return $item->getLabel();
}
