Hi, this is Bilal from Science Exchange. Appreciate your concern, but that is why we feel Science Exchange is uniquely positioned to make a difference. We have developed a network of 1000 core facilities and CROs on our platform, who operate on a fee-for-service basis to conduct experimental services. The Reproducibility Initiative will leverage this network to outsource specific experiments within a study to these facilities.
It is quite common for experiments to be replicated, usually as preliminary to a further advance.
If the findings claimed are significant enough, other labs will often attempt to replicate a few of the key experiments, and if they don't do so quickly, abandon that direction of investigation, and not report their negative findings.
Reproducing experiments seems like a costly (and mostly thankless) effort that few PIs would ever take up.
The only journal I know of that completely reproduces results is Organic Syntheses (http://www.orgsyn.org/), which reproduces every reaction before publication and has a Procedure Checklist for authors: http://www.orgsyn.org/AuthorChecklist.pdf
