Two solid entry points, depending on what's bothering you most. Start with Colon Gentle Cleanse ($34.99) if your day-to-day digestion is the unpredictable part — irregular, gassy, stool not quite right. Single-ingredient psyllium, you'll feel the difference in 5-7 days. Start with Probiotic 40 Billion ($30.99) if digestion is mostly fine but you want to build the microbiome layer underneath — slower payoff, longer-lasting effect. Either is a sensible first buy. The full Bundle ($99) is there if you'd rather skip the choice, but you don't need to start there. Pair whichever you pick with our Bottoming Diet guide for the daily eating piece.

Colon Gentle Cleanse is psyllium-based fiber — softens stool, makes the colon move predictably, cuts how often you actually need to douche. Probiotic 40 Billion is 4 strains of live bacteria + prebiotics — supports the gut microbiome long-term. Fiber is the daily routine, probiotic is the foundation underneath. Most experienced bottoms use both — see our breakdown on psyllium husk capsules.

Recovery Cream is a balm for soothing the skin around the anus after sex — aloe, shea butter, and olive oil base. Built to clinical skincare standards: no fragrance, no parabens, no artificial dyes, gender-inclusive. Yes, sensitive skin can use it — that's actually the point. Most post-sex balms re-irritate because they're packed with cosmetic additives; this one is deliberately the opposite. For the full aftercare routine (the first 30 minutes, the first 24 hours, when to see a doctor), see our anal aftercare guide.

Day 3-5: softer stool, more cohesive bowel movements.
Day 7-10: bowel rhythm normalizes — you start going around the same time daily.
Day 14+: this is your new baseline. Don't quit at day 4 — the first week has transient adjustment effects (mild bloating, slight gas) that resolve as your gut adapts. The 2022 PubMed meta-analysis on fiber backs this timeline.

Yes — both are designed for daily use. Psyllium husk has decades of clinical evidence supporting daily intake at 5g doses (Mayo Clinic on fiber); your body doesn't develop tolerance and there's no "withdrawal" if you stop. The probiotic is similar — strain-specific live cultures meant for daily routine use. The one rule: drink enough water (16oz with each fiber dose, 2.5L total daily). If you have an existing condition (IBS flare, severe constipation, pregnancy, GI strictures, or you're under 18), use your own judgment and check with a clinician first — these are food-grade supplements, not prescriptions, but you know your body better than we do.

No — same 5g daily dose, same time every night. This is the most common new-customer mistake. Doubling fiber for a few days doesn't make you cleaner; it usually makes you gassier and crampier right when you don't want to be. The way psyllium works is by giving your colon time to learn a rhythm — that takes 7-14 consistent days, not a 48-hour sprint. The honest version: a steady boring routine beats any pre-game loading every time. If you're new and your sex day is this Saturday, just start the routine now and accept that next weekend will be smoother than this one.

Take psyllium 1 hour apart from medications. Psyllium binds to some pills (thyroid meds, lithium, some antibiotics) and reduces absorption. Probiotics are generally fine alongside PrEP and most medications. If you're on prescription meds, talk to your prescriber. PrEP itself stays highly effective regardless of cleansing or supplement routines per CDC PrEP guidance — it's the gold standard for HIV prevention in receptive anal sex.

Yes. All orders ship in plain brown boxes with no PrepFlora branding visible from the outside. The shipping label only shows "PrepFlora" as the sender — no product names, no descriptions, no anything that suggests what's inside. Inside the box, products are in their normal retail packaging. We've thought about this carefully because we know how it matters.
