Sythol used at the last moment like that is not how it is intended for it to be used at all, that is synthol abuse.
Synthol therapy stretches the muscle fibres allowing for more muscle growth to a stubborn bodypart, with proper application of synthol you wouldn't to be able to tell he had had injections at all.
Those pics you always see of synthol users are not the typical synthol user at all but its abusers, nothing more then a freakshow. Synthol is not mean't to be used as a last minute fix but part of a wel thought out program to add more muscle to an already developed body.
