MIRATION is the sincerest form of flattery, and the world-wide success of 'ASPRO' has produced -a crop of substitutes in tablet form which resemble 'ASPRO.'
Some of these imitations contain cheap and impure salicylic acid, others are compounded from different ingredients, some of which can be positively injurious to the system. Any manufacturer can state that his medicinal product is pure, but it is quite a different matter to publish an authoritative statement that a medicine conforms to the standard of purity laid down by the British Pharmacopoeia (the guiding authority of the Medical Profession).
'ASPRO' conforms with this standard and is therefore safe and pure, leaving no dangerous after effects—no doping—and furthermore 'ASPRO' does not harm the heart.
