Frequently asked
What is the difference between healing & recovery and skin & hair peptides?
Healing & Recovery peptides — peptides researched for tissue repair, wound healing, and injury recovery — most commonly act through angiogenesis & vegf modulation or actin sequestration & cell migration or copper-dependent gene modulation. Skin & Hair peptides — peptides researched for dermatological applications — most commonly act through copper-dependent gene modulation or non-selective melanocortin agonism. Beyond mechanism, the classes differ in FDA approval mix (0 approved in healing & recovery vs 0 in skin & hair) and in the depth of human clinical evidence available.
Which class has more FDA-approved compounds?
The healing & recovery class currently includes 0 FDA-approved compound(s) out of 3 tracked. The skin & hair class includes 0 FDA-approved compound(s) out of 2 tracked. FDA status matters because it governs legal availability through compounding pharmacies versus prescription-only dispensing.
Which class has more clinical research?
Healing & Recovery compounds collectively account for 343 indexed studies, with 15 involving human subjects. Skin & Hair compounds account for 155 indexed studies, 14 human. More studies does not always mean stronger evidence — the quality and design of those studies matters more than raw count.
Can healing & recovery and skin & hair peptides be combined?
Combination protocols across these classes exist in clinical literature and integrative medicine practice, but most evidence for combination safety is weaker than for either class alone. Any stacking decision should involve a qualified clinician familiar with both classes' pharmacology, drug interactions, and overlapping adverse-event profiles.
How do I choose between healing & recovery and skin & hair?
The choice is driven by the therapeutic goal. Healing & Recovery is most appropriate when researched for tissue repair, wound healing, and injury recovery. Skin & Hair is most appropriate when researched for dermatological applications. A qualified clinician can evaluate which class aligns best with your medical history, goals, and regulatory context.
