It looks as though this Vostok V1 thermal compound is trying to revive the old nail polish bottle approach that was popular 15 years ago. As long as what's in the bottle does its job, who cares what type of bottle / syringe it comes in.
Of course, as we all know, not all TIM is made the same and nor is all TIM as effective at this job. For example ‘stock’ TIM that comes pre-applied to Intel and AMD stock cooling solutions can be upwards of 10-degrees or more hotter running than if say Artic Silver MX-4 is applied. That is a massive difference and can mean the difference between an overclock being thermally limited (and being a failure) and one that is still well within the operating temperatures we all strive for.
