Trying injectable biotin for hair and skin – curious about dosing and results

Posted by brandon245 in Longevity & Anti-Aging - 1 points, 0 comments.

Hey folks, I’ve been seeing a lot of ads for high‑dose injectable biotin lately and I’m wondering if anyone here has actually tried it. I’m a retired firefighter on the East Coast, pretty new to the peptide and supplement scene, mostly interested in longevity and skin health. The usual oral biotin never seemed to do much for my thinning hair or brittle nails, so the idea of bypassing the gut with an IM shot caught my eye.

The reference says typical dose is 1‑10 mg once or twice a week, half‑life around two hours. Not gonna lie, I’m a bit nervous about possible acne or lab test interference, but I’d love to hear real‑world anecdotes. Did you notice any difference in hair growth, nail strength, or skin texture?

How did you handle injection site soreness? Any tips on cycling or stacking with something like spermidine for autophagy?
