Halloween Sales are here and more on the way!

Randy

We’ve pulled together the Halloween sales and other vendor promotions announced to Peptide Critic, including what’s running now and what’s scheduled for Halloween weekend.

Last checked: October 26, 2026.

Halloween falls on Saturday this year. Most of these sales finish October 31, while Studz and Hydro have confirmed offers extending into Sunday, November 1. Exact deadlines are listed in Pacific time where the vendor provided enough information to convert them.

Halloween weekend sales

Studz Aminos — October 30–November 1

Use code SPOOKY for tiered discounts:

15% off orders under $200.
20% off orders from $200–$549.
25% off orders from $550–$1,999.
30% off orders of $2,000 or more.

The sale runs Friday through Sunday. The flyer doesn’t specify an exact ending hour or additional stacking terms.

Mile High Compounds — Buy 2, get 1 free

Running October 26–31.

Mix and match three eligible vials or capsules, and the cheapest item is free. The sale applies automatically at checkout. An eligible 10% affiliate code can also stack.

Updated exclusions and terms:

MHC-3 RT is excluded in every size.
Solvents and sprays are excluded.
Bulk pricing does not apply to sale items.
The first-order offer is paused during this promotion.
Both new and returning customers can participate.

Ends Saturday, October 31, at 10:59 p.m. Pacific.

October 27–31 is the corrected sale window. No exact ending hour was included in the announcement.

Voltera Sciences — Sitewide sale with additional discounts

Running October 26–31:

35% off sitewide automatically.
An additional 10% with an eligible partner code.
An additional 5% when paying with Zelle, Venmo or Cash App.

Bacteriostatic water is excluded.

Voltera advertises this as “up to 50%,” but the final percentage depends on how checkout applies the discounts. Check the actual total rather than adding the percentages together.

Crush Research — Halloween Haul and Pack Attack

Running through October 31.

Mix-and-match pack discounts are increased to:

20% off a three-pack.
25% off a five-pack.
30% off a ten-pack.

Code CRUSHMAIL takes another 10% off the discounted pack price.

The vendor is also advertising separate product specials. Its Triple Agonist 20 mg ten-pack was listed at $233.10 with CRUSHMAIL, or $221.45 with the additional Zelle/crypto discount, subject to availability.

The stated deadline is October 31 at “midnight Mountain time.”

NexPept — Halloween sale for Canadian customers

Use HALLOWEEN for 15% off all products through October 31.

The vendor’s flyer advertises these combined discounts when the code is used with Mix & Match:

Three vials: 20% off.
Five vials: 25% off.
Ten vials: 35% off.

NexPept ships within Canada only.

ION Peptide — Anniversary finale, October 26–31

ION is advertising up to 45% off sitewide, plus three flash-sale items each day.

Flash offers have limited quantities and a limit of one per customer, per item.

The sale graphic confirms the October 26–31 dates but does not give a coupon code or explain the full “up to 45%” calculation. Individual flash prices can change as offers rotate or sell out.

Running now, but ending before the weekend

Instant Peptides — BOGO on October 26 only

Buy one, get one free on the advertised GLP-1 SM, GLP-2 TRZ, GLP-3 RT, Cagrilintide and RT/CAG products.

Add two of the same eligible product and size to the cart. The second is free automatically; no code is needed.

Ends Monday, October 26, at 8:59 p.m. Pacific.

Instant says more daily Halloween offers are coming this week, but the complete schedule has not been announced.

Upcoming announcement to watch

Southern Aminos has announced a Halloween event beginning October 29, but has not revealed the actual offer yet.

It also runs random flash drops. Example prices in its emails are not necessarily live offers or scheduled to return, so check the current listing and timer.

Updates and corrections

These details come from vendor emails and promotional flyers received by Peptide Critic. Stock, eligibility and checkout terms can change.

If a code stops working, a vendor extends a sale, or you find a newly announced offer, reply below with the vendor name, code, expiration date and a link to the announcement. Vendors are welcome to clarify their terms too.

Anyone even seen one of the ion peptide flash deals yet? I can’t even tell where it would show on their site.

@84.brig_tailor Flash deals are usually only on there for a few minutes so you have to be on their page and refresh it randomly throughout the day to catch one. Same thing for Southern Aminos, I always miss them.

Bummer. I am very busy this week at work. Probably won’t be able to catch one.

@84.brig_tailor Yeah that's frustrating, work frequently takes me away from my personal phone for hours at a time so the whole "drop" thing rarely works for me.
