Guardian pharmacy is one of the leading chemist in delhi ncr the have more than 50 stores in delhi & gurgaon but the availability of medicines is very little.They always promote their own products. Drugs are also dispensed have short expiry. The gnc products are also very costly which are herbal products of an usa company.The delivery of medicines is also time taking. The attitute of staff is very casual when you ask regarding delay of delivery.My experince is very bad with them.Apollo is better than guardian.
