The evidence base is narrow and indication-specific, and it does not support PRP as a longevity or healthspan protocol. There is genuine randomised human trial evidence for a small number of localised indications, principally androgenetic alopecia and some tendinopathies, with mixed and heterogeneous results driven by wide variation in preparation protocols (spin speed, platelet concentration, leukocyte content, activation method), which makes trials poorly comparable and results hard to generalise. For knee osteoarthritis, the most-studied longevity-adjacent indication, the larger and better-controlled trials have not shown benefit over saline injection. Critically, there is no evidence at all that PRP affects any systemic ageing outcome: no trial has shown an effect on biological age, mortality, healthspan, or any organ-system-wide measure. Its use as a "regenerative longevity" offering is a marketing extension of a local, cosmetic and musculoskeletal treatment, not a supported healthspan intervention, so it is graded commercial. Regulatory verification was incomplete and this is a material limitation of this profile: repeated live fetches of tga.gov.au (the TGA PRP/PRF/conditioned-serum guidance, the ARGB overview, and the autologous HCT PDF) all timed out across multiple attempts, so no TGA position is asserted here and auStatus is returned null rather than guessed. A credible secondary source (MIPS, the medical indemnity insurer) confirms the general shape of the Australian autologous human cell and tissue framework, including that products manufactured and used in an accredited hospital by a practitioner for their own patient sit outside TGA regulation, but that source does not mention PRP, so it cannot establish where PRP falls. For Singapore, HSA product-level status under the Cell, Tissue and Gene Therapy Product framework (in force since 1 March 2021, Class 1 versus Class 2 by degree of manipulation) could not be verified for PRP specifically. What was verified is a professional-practice restriction rather than a product approval, described in sgStatus. Offering confirmation is solid for Australia and absent for Singapore: Bespoke Longevity's own itemised treatment menu lists PRP explicitly across five indications with prices and membership bundles. PRP is near-ubiquitous in Singapore aesthetic practice, but no service page for any named Singapore longevity clinic stating PRP was opened, so Singapore is recorded as unconfirmed rather than absent.

What it is
PRP is made by drawing a patient's own blood, spinning it in a centrifuge to concentrate the platelet fraction, and injecting that concentrate back into the same person. The rationale is that concentrated platelets release growth factors that accelerate local tissue repair. In longevity and aesthetic practice it is sold for facial rejuvenation, hair regrowth, and joint pain, and is sometimes framed as a "regenerative" or anti-ageing intervention.
