Looks like Nexaph has a 20% off as well and stacks with 5% if paid with Crypto.

[ResearchCat]

You are the man! So many sales!

Not sure if we have a code for Biolongevity Labs but they have a big sale on too.

[vpeps]

Rat race is on!

[e_kantor2]

All these sales are good but the prices are marked up so high that it's still crazy prices

[Sunshine-day]

@e_kantor2 Agreed. It's rather disappointing.

[BeeKind]

@e_kantor2 I agree the marketing tactics most of them use are scammy and not real sales. Nexaph's sale is legit though. Their prices are pretty steady.

[documentswitch]

Not much of a sale if you ask me.

[wes33378]

I can't stack peptidecritic with the Labor Day promo at Nura. 30% + buy3 get one works.

[damic]

@randy Confirm, no stack @ https://nurapeptide.com

[Sunshine-day]

@wes33378 I couldn't either. But even with an extra 20% off, it still wasn't going to be much of a discount on Reta.

[Randy]

Genpeptide Now Stacks!

[MyB]

Can’t forget your own sale, little rat dude!
I lost it over JeffedUp

[e_kantor2]

So depressing I haven't seen one good sale outside of Nexaph lol

[Stevepep]

@MyB looks like more V3 ultras my wife is living them

I remember what they did on sales for the 4th is at the last minute, some sites would do unannounced markdowns, some were very significant. Give it time. Most likely to happen Sunday or Monday. They're no doubt trying to clear out for EOY holidays, so, stay with it and watch.

What do you mean? If you put a 24mg kit of reta in your cart from Nexaph and one from EZ, the kit from EZ is $30 less after all the discounts ($396 vs $369). Not all items are less, but if you shop around there are better prices to be had.

@shifted you must have better prices than the rest of us.

Yeah, you need to select crypto as the payment method to get the full discounts on both sites. Extra 5% on Nexaph and an extra 10% on EZ.
