The second Synthetek essay in the recovered set explains site-enhancing oil: a sterile preparation injected into a muscle to increase its volume, with the argument built on tissue response, oil clearance and the difference between temporary swelling and retained size. It is a product essay rather than a review, and the risks it plays down are real. It stays in the index for completeness, not as guidance.
