What did @popethecoach actually say?
He's being pretty straight with his audience here. He confirmed he developed back acne after starting TRT, noting "I didn't have back acne before," and that some chest involvement followed. He mentioned hearing that zinc supplements help but also that they cause nosebleeds, so he's avoiding them. Instead, he's using a salicylic acid wash ("Sarah V. Wash" is almost certainly Salycilic acid-based CeraVe or a similar product) and has beef tallow moisturizer on the way. No wild cure claims, no dangerous stacking advice. Just a guy documenting his experience and asking for community input.
The honesty here is actually refreshing compared to a lot of TRT content online. He's not selling anything or claiming he solved the problem. That said, there are a few gaps in what he's sharing that are worth addressing.
Does the science back this up?
Yes, TRT-related acne is well-documented and he's not imagining it. Exogenous testosterone increases sebum production by binding to androgen receptors in sebaceous glands, which is why the upper back and chest, areas dense with those glands, are common breakout zones. This is not placebo effect or coincidence.
On zinc: the evidence is real but modest. A 2012 meta-analysis by Gupta et al. in Dermatology found oral zinc reduced acne lesion counts, though it consistently underperformed compared to oral antibiotics. The nosebleed concern is legitimate too. High-dose zinc supplementation (above 40mg daily) can irritate mucous membranes and interfere with copper absorption. He's right to be cautious, though therapeutic doses used in acne studies are typically 30-45mg zinc gluconate, not megadoses.
Salicylic acid washes have solid evidence for comedonal and mild inflammatory acne. Beef tallow as a moisturizer? The science is thin. It's trending in wellness circles but there are no rigorous clinical trials supporting it over established options like niacinamide or ceramide-based moisturizers for acne-prone skin.
What did they get wrong (or right)?
He got the core experience right. TRT-induced acne is real, the back and chest distribution makes anatomical sense, and salicylic acid is a reasonable first-line topical approach. Credit where it's due.
Where he's on shakier ground: the zinc-nosebleed framing is a bit oversimplified. Nosebleeds at standard therapeutic doses are not a common documented adverse effect in acne trials. That concern likely comes from anecdotal community reports or from people taking much higher doses. He may be avoiding a modestly effective option based on incomplete information.
The beef tallow recommendation is unverifiable at best. It contains oleic acid and some fat-soluble vitamins, and some practitioners think it mimics skin lipids, but for acne-prone skin, high oleic acid content can actually be comedogenic for some people (Kanlayavattanakul and Lourith, 2011, International Journal of Cosmetic Science). This one needs more scrutiny before it gets recommended widely.
He also doesn't mention talking to a dermatologist, which for persistent TRT-induced acne is genuinely the most effective path.
What should you actually know?
If you're on TRT and developing acne, this is a known, manageable side effect, not a reason to panic or stop treatment without talking to your prescriber. Androgens upregulate sebaceous gland activity, and exogenous testosterone simply accelerates that process in susceptible individuals.
First-line options with actual clinical evidence include topical retinoids (tretinoin, adapalene), benzoyl peroxide, and salicylic acid. For moderate to severe cases, a dermatologist may consider oral options. Zinc supplementation at appropriate doses (not megadoses) has supporting evidence but is generally considered an adjunct, not a primary treatment (Dreno et al., 2018, Journal of the European Academy of Dermatology and Venereology).
Moisturizing acne-prone skin is actually important, as over-drying inflames the barrier and can worsen breakouts. But the choice of moisturizer matters. Look for non-comedogenic, fragrance-free formulations. Beef tallow is not currently supported by clinical evidence as a superior option and may not suit everyone's skin type.
Most importantly: if your TRT provider hasn't asked about your skin since you started, bring it up. Acne management should be part of ongoing hormone therapy monitoring, not something you're crowd-sourcing on TikTok alone.
