Health Deals Radar — June 5, 2026

Two things changed overnight that affect active shopping decisions: GNC's Ghost BOGO 50% deadline moved up by one day (now June 10, not 11), and ALLSITEWIDE15 — Vitacost's 15% sitewide safety-net code that was supposed to hold through June 7 — has vanished from coupon aggregators. A new iHerb code targeting heart health products rounds out today's increment. Everything else carried forward from June 4 remains active.

Coverage window: June 4, 3:20 PM ET → June 5, 2:00 PM ET.

Expiry watch — act before the weekend

Jun 7 cluster: 3 Vitacost sitewide codes + Costco May book

Vitacost Jun 7 codes — one fewer than yesterday. ALLSITEWIDE15 (15% sitewide), which was showing a June 7 expiry as recently as June 4, no longer appears on DontPayFull (which listed 29 active Vitacost codes in today's sweep) or on Offers.com (21 active codes). 1 2 Whether it expired early or was pulled by the aggregator is unclear — SimplyCodes returned a 404 today and couldn't serve as a third-party check. The three remaining Jun 7 codes — CYBERSMS20 (20%), LIFE20 (20%), and SITESALE15 (15%) — are still active and recently used. Use a 20% code on any general cart before Saturday. SITESALE15 had its last community confirmation three weeks ago, so treat it with slightly more skepticism than the other two.

Costco May book — final 3 days (expires June 7). Orgain Collagen Peptides + Probiotics is at $23.99 (regular ~$29.99) and Ensure Original Nutrition Shake is at $28.99 (regular ~$37.49), both applying automatically at the warehouse register. 3 No code or coupon required — just a Costco membership. These disappear Sunday.

Jun 8 cluster: GNC PRO BOGO + PUMPAF + Vitacost Jun 4 batch

GNC PRO Access BOGO 50% Mix-and-Match (11 brands: Optimum Nutrition, GHOST, Alani Nu, GNC AMP, Beyond Raw, GNC Pro Performance, RAW Nutrition, RYSE, Gorilla Mind, Axe & Sledge, Alpha Lion) expires June 8 and requires a GNC PRO Access membership. 4 Verified 6 hours ago with 5 community confirmations.

PUMPAF — $10 off when GNC Creatine and Beyond Raw LIT AF v2 pre-workout are in the cart simultaneously — also expires June 8. 5 Both items must be present; the code won't apply to creatine alone.

Vitacost Jun 4 brand batch (Jun 8 sub-set): QUALIA25 (25% off Qualia, a nootropic supplement brand), ALLANCIENT (15% Ancient Nutrition), 20SOV (20% Sovereign Silver/Copper), 15BADGER (15% Badger), 20THINKBRAND (20% Think Brand), HAWAII (20% Nutrex Hawaii), WKND2 (25% Olympian Labs) — all expire June 8. 1 Use these before the weekend if your cart includes any of those brands.

GNC — Ghost BOGO deadline moved to Jun 10, new BUM Energy in-store offer

GNC and Ghost celebrate Ghost's 10th birthday with BOGO 50% off all Ghost products, ending June 10 — GNC homepage banner showing Ghost's 10th anniversary BOGO 50% off sale. End date is now June 10 — one day earlier than the June 11 date reported June 4. 4

GNC's Ghost Birthday BOGO 50% — available to all shoppers, no PRO membership required — now shows "Ends 6/10" on the homepage banner. 4 Yesterday it showed June 11. The promotion covers the entire Ghost line: Whey Protein, Amino, Legend pre-workout, Greens, Hydration, and energy drinks. BOGO math: the discount applies to the lower-priced item, so two Ghost Whey tubs at $54.99 each comes to $82.49 for the pair — $27.50 saved.

A new in-store-only deal: BUM Energy BOGO Free (buy one, get one free) at select GNC locations, also ending June 10. 4 Purchase limits are 12 single units and 4 cases for PRO Access members, 6 single units and 2 cases for everyone else.

GNC PRO Access member exclusive BOGO 50% off almost everything banner — GNC PRO Access BOGO 50% Mix-and-Match across 11 brands — expires June 8, PRO members only. 4

The PRO Access BOGO 50% Mix-and-Match covers 11 brands (listed in the expiry-watch table above) and expires June 8 — three days earlier than the Ghost everyone-gets-it promotion. If you have a PRO membership and a cart full of one of those 11 brands, the PRO tier is generally the better deal because you can mix products across brands rather than buying two of the same item.

iHerb — new heart health code, all existing codes confirmed active

New this sweep: MAY26HH gives 15% off eligible heart health products (CoQ10, omega-3, magnesium, blood pressure support supplements) and expires June 10. 6 Captured June 1 by a DontPayFull user and staff-verified June 3. One verification so far — lower confidence than the long-running codes, but the staff verification adds credibility.

All other iHerb codes confirmed active in this sweep: OM183 (10% off, GCC region, Jun 7 — verified 4 hours ago by 18 people); EST26 (20%, Jul 5, 13 verifications); DRBEST26 and KBF3096 both confirmed within the last few hours. 6

US shoppers — priority order for today:

EST26 — 20%, expires Jul 5, 13 verifications (highest confidence)
DRBEST26 — 20%, Jul 5, confirmed today
MAY26HH — 15%, Jun 10, heart health products only (new, 1 staff verification)
MAYAPP15 — 15%, Jun 10, iHerb app only
GOLD60 — 10%, $60+ carts, no expiry, 929 verifications (reliable fallback)

iHerb accepts one promo code per order. EST26 and DRBEST26 both offer 20%; test EST26 first, and if it doesn't apply, try DRBEST26.

MyProtein — 40% sitewide and $9.99 creatine unchanged

MyProtein US's 40% off almost everything auto-discount and Creatine Monohydrate Powder at $9.99 (auto 50% off from $19.99) are both confirmed active on the June 5 homepage. 7 No changes from June 4. The "Up to 50% off Creapure" banner (Creapure is a patented high-purity creatine monohydrate from Germany) also remains, linking to Clear Whey Isolate.

Free shipping threshold is $99. The $9.99 creatine alone doesn't clear it, but adding any item at 40% off typically covers the gap.

Amazon deals — Vega plant protein 59% off, ON Whey still at $41.50

Vega Protein + Creatine (30g plant-based protein, vanilla, 2 × 33.9 oz) is $35.74 ($17.88 each) on Amazon via Subscribe & Save plus a 30% multibuy coupon clip. 8 The original list price for the pair is $88.18, making this 59% off. Posted this morning by Slickdeals Staff, Deal Score +2. With the S&S 15% tier (if you're eligible), the final price drops to $26.92 for the two-pack.

Amazon product listing grid showing Orgain, Optimum Nutrition, and other protein brands on sale — Amazon protein deals as of June 4–5, including Optimum Nutrition Gold Standard Whey at $41.50 and Orgain Organic Vegan at $26. 9

From the June 4 9to5Toys roundup (deals still active unless otherwise noted):

Product	Sale price	Regular price	Savings
Optimum Nutrition Gold Standard 100% Whey, 2 lb (Vanilla Ice Cream / Cinnamon Roll)	$41.50	$57.00	27% off
Orgain Organic Simple Vegan Protein Powder	$26.00	$30.00	13% off
Garden of Life Vegan Protein Powder	$34.00	$51.00	33% off
Premier Protein Shake, 12-pack	$26.00	$35.50	27% off
Ensure Max Protein Shake, 12-pack	$28.00	$38.00	26% off
Lenny & Larry's Complete Protein Cookie, Snickerdoodle 12-ct	$8.49	$23.49	64% off
Pure Protein Bars, 36-count	$44.00	$64.00	31% off

The ON Whey at $41.50 is a 27% discount — below the 40–50% threshold Slickdeals typically requires to generate a community post. It's not a standout deal on its own, but paired with a Subscribe & Save subscription it's a reasonable buy-in price for a reliable product if you're already stocked on Vitacost or iHerb codes.

Vitacost — stacking guide for the Jun 7–8 cliff

Vitacost allows one code per order. With ALLSITEWIDE15 gone and the Jun 7 cluster down to three codes, here's the priority ladder for the next 48 hours:

Before June 7 (tonight through Saturday):

CYBERSMS20 or LIFE20 — both 20% off, both active as of today. Use whichever applies at checkout first. SITESALE15 (15%) is a fallback if neither of those goes through; last confirmed three weeks ago so test it.
TEXT10 ($10 flat off) — outperforms percentage codes on carts below $50.

June 8 deadline brands (use before Saturday):

QUALIA25 (25% off Qualia Mind / Focus), 20SOV (20% Sovereign Silver/Copper), 20THINKBRAND (20% Think Brand products), WKND1 (30% Jigsaw Health, a magnesium and electrolyte supplement company — the best single-brand rate in the current batch)

Still available after June 8:

ANNIE15 (15%, expires Jun 9) — 37 verifications over its lifetime, last confirmed May 30; still listed but test before trusting.
Jun 15 batch (IRWIN, MERCOLA, NONGMO, PRIMA20, 20BARK, ALLCABOO20, TREETOTUB) — 20% off their respective brands, more time to plan.

Costco — Day 4, still no adult supplement deals in June book

Costco's new "Weekly Warehouse Insider" format (replacing the traditional June+July coupon book) covers June 1 through July 5, and as of today its only health supplement deal is PediaSure with OptiGRO Plus Kids Shake (vanilla, 24-count) at $29.99 after $8 off (item #1268174, limit 10, valid through June 28). 10 Zero adult protein powders, vitamins, sports nutrition, or fitness equipment appear in the current format.

CostcoInsider.com still lists the traditional "June 2026 Coupon Book" as "upcoming" in its sidebar — suggesting the old-format book may still be planned — but no release date is confirmed and no health supplement deals have surfaced through this format. 3 This is now Day 4 of a gap in the June adult supplement cycle.

What remains from the May book (Costco warehouse, expires June 7):

Orgain Collagen Peptides + Probiotics: $23.99 (save ~$6 off regular price)
Ensure Original Nutrition Shake: $28.99 (save ~$8.50 off regular price)

Both apply automatically at the register with no coupon required.

BPN — subscription-only model confirmed at Day 7

Bare Performance Nutrition (BPN) has not issued a sitewide promo code for the seventh straight day since SPRINGFIT expired May 31. 11 The only active sitewide promotion is 25% off all new subscriptions (no code needed, applied at checkout). Subscription prices with the 25% off: Whey Protein $37.49, Creatine $26.24, G.1.M Sport $29.99, Electrolytes $33.74, Go Gels $39.99.

The new Maple Cinnamon Go Bar remains BPN's featured product launch: 34g carbs, 200 calories, with cinnamon and maple flavoring positioned for endurance or long training sessions.

There is no aggregator-listed BPN sitewide code as of this sweep — the pattern of periodic flash sitewide discounts has not resumed.

Whey drought — Day 6

No whey protein deal appeared on Slickdeals supplements in today's window. 12 Amazon has Optimum Nutrition Gold Standard Whey at $41.50 (27% off), which falls below the discount depth Slickdeals typically posts. The best protein-category deal available at any major retailer today remains MyProtein's $9.99 creatine monohydrate. Plant protein has a standout exception in the Vega 59%-off Amazon deal above.
