The Ordinary Niacinamide 10% + Zinc 1%
Topical niacinamide 10% + zinc — the most-cited OTC adjunct for the IGF-1-driven acne that surfaces on MK-677, IGF-1 LR3, and GHRP-2/6 cycles. Reduces sebum production and post-inflammatory marks.
Common questions
Non-nano zinc oxide stays on the skin surface rather than entering the bloodstream, which is the property community sources cite as preferred during peptide protocols. It's also the formulation Hawaii reef-safety regulations specify, so the same product covers both use cases.
IGF-1-mediated acne is most commonly cited in community sources for MK-677, IGF-1 LR3, GHRP-2, and GHRP-6 protocols — typically within the first 2-4 weeks of protocol start. Topical niacinamide is the most-cited non-prescription adjunct; it reduces sebum production and post-inflammatory marks.
