Precision Peptide Co. vs. NextaPH vs. Skye vs. ??? Recommendation help!?!

[chnkymnky]

Howdy all. I just joined and I'm researching where to buy semaglutide 10mg. I'd previously had purchased from Precision Peptide Co., but now that they only do wire transfers and the fact that my last order smelled like chlorine, plus the fact that they've removed the lab analysis results for it from their website, has me a bit worried...

I'm wondering where the best place to go is currently? In going through this forum, it looks like Skye or NexaPH? NexaPH is definitely cheaper per vial, and both Skye and NexaPH have recent lab tests. Might anyone have an opinion? Looking to pick up a year supply of this so I don't have to go through this quest again for awhile!

Note that while I've been using Precision Peptides since late December/early January, I've got a friend who's been using them for around a year and a month - she recommended Precision Peptides to me and the results have been great! But...definitely looking for advice since I'm likely going to need to switch suppliers? Thanks to all in advance!!!

Check out this section of the forum, and search up anyone whose sales you find you like the price list of. The list is not vetted, so you'll want to read actual members posts about the vendor to make a decision.

Curious on what you have in mind as far as a years supply. What's your current mg per week? Do you plan on staying there or moving up?

Yeah, I would find something cheaper, especially with the recent quality issues with Nexa/ph:

Nexaph vial foreign objects?

May 29, 2025

Hello all,

I know many here are SNP customers. I’ve noticed a bit of an uptick in people finding random shit in their vials/on their pucks. Just today a couple members pointed out specks of black or some foreign matter in their vials.

I will attach here what was said/found. I know Cain deals with these very well, but I question what their lab processes are and how clean of a UGL they have.

The most recent instances were from MOTS-C and Reta 12.

SRY has had similar issues. By their own admission, SRY had vial stopper rubber pieces in some of their vials. Since then, SRY has had underfill issues, which they may be resolving, besides offering them at a discount.

Compared to the US "warehouses" for the Chinese vendors, Nexa and PGB are truly domestic shippers that always know what they have in stock (though of course the products are all from China, as with Skye and everyone else).

OTOH:

It’s funny, nexa is a group buy posing as a vendor, pgb is a vendor posing as a group buy.

When buying from PGB directly, they require crypto and aren't cheap for shipping. But using one of their reshippers can help on both fronts. My only interest in PGB though is their survo pricing, and I will probably get reta or more triz next time, from China.

If you get something cheap enough directly from China, you can test it yourself with the money you save. The best example to me is 34 cents/mg for tirz from SSA.

In case you missed it from your duplicate thread I responded;

Spend sufficient time here and you'll spend very little for Sema... It's not a riddle or puzzle. Sufficient time is like 5 minutes to 44¢/mg!

Yes! .88¢ per week for 2mg (max Ozempic) dose.

I have purchased from both Skye and Nexaph and like them both. Nexaph is like the Costco of peptides since you buy in bulk. I like that they have volunteers send vials for 3rd party testing. Skye is single vial, but they test their products for not only purity and fill, but also sterility and endotoxins. Both are great so it depends on your budget.

 

[Peptelligence]

My starting experience was with Skye to the COAs. They are quite professional too. And I think someone mentioned you can request Bac Water with your order. But overall, they were a good starting place for me and I could trust the vendor.

I wouldn’t buy from any one of them. Sky is a reseller. Nexeph is a reseller. Precision is a reseller. Why bother coming to a grey information group only to spend more money for something you could find without this place?

 

[Calm Logic]

The compounded pharmacy I used, Brello Health, charged much less than Skye does.

Skye seems to charge $419 for a single vial of T60:

I got 180 mg of ready-to-inject tirz from Brello for $499.

Do we need to refrigerate the powder ?

 

[Calm Logic]

No, at least not for most peptides like GLP-1s, but it would be ideal to freeze it. Not only to prevent degradation but also to preserve sterility (as discussed in previous posts).

Slowly over time, refrigeration can introduce more moisture than freezing if there are even microscopic gaps in the vial from an imperfect seal. Moisture is a bad thing for peptide powder and preserving sterility.

But peptides like tirz would be fine no matter what really, even with some degradation due to poor storage in hot environments. Being in a hot UPS or USPS truck has probably no real effect, I assume, since it is a small amount of time.

I've used Precision and Skye many times for things I don't need a kit of. I prefer Skye only because shipping seems a little faster and they send a sticker. Can't go wrong with either.

my working baseline been 3-4 months at -20°C reconstituted

on the freezer front: lab grade is out of reach for me atm, but i did find a 3.5 Cu Ft Northair 574BG30006N2 that'll run down to -40C/F with digital setpoint:

(could be a re-label available elsewhere)

As long as you know it's completely overkill. Jano has shown lyophilized peptides to be stable at room temperature for over a decade.

if you have the reference, i'd appreciate it so i can add to my notes

You can email Janoshik and ask him.

I've seen him say it in some other chats. I believe the detail was mt2 in the garage for 12 years testing over 95%.

I think there are some youtube videos of him being interviewed where he mentions something similar. They are worth the watch anyways.
