Peptide Critic Community

I wanted to know if there is a real difference between various V2 peptide pins In terms of build quality. I mainly buy them here but I have purchased a few other on the open market mainly as an experiment. But I had a pen cartridge holder fail on me today. The plastic housing came away from the silver ring that attaches to the pen plunger part. I think the housing on my Gansolin pen may be metal but I am wondering if there are any peptide pen brands that use a glass cartridge holder, instead of the plastic.

Looking at echemi makes me really wonder if this entire industry is a inside joke im not in on. That being said.

@HockeyRat While I haven't had any ISR with either MOTS-c or SS-31, switching to a longer needle (8mm vs 5mm) made a world of difference with NAD+ and Glutathione.

Are you combining the peptides into one injection? That’s asking for pip if so. MIT.

Theres a round spring loaded retaining ring at the base of the rod that the cartridge depresses. Push on that and wiggle the threaded part to release it.

I bought a stainless holder that came with a couple of ice packs for travel. My intended use is to keep in the fridge without drawing undue attention. It looks like a stainless water bottle except for the thermometer on the lid. (I suppose I can put it in there upside down!) https://a.co/d/0gJF0LLt I don’t currently have a 3d printer but I envision an insert SOR three pens with a hole in the center for the temperature probe. Perhaps there would even be room for a second tray for vials. (Or dinosaur embryos!) [image: 1784315626230-c276d2d1-d2bd-4ecb-816f-6fc1b8a71cc8-image.jpeg]

The hits keep coming for Puratek, other than on social media. These guys must be paying everyone with freebies. The feed on TikTok is nuts, it never ends

@gym.rat I have had nothing but good experiences from them. What else has happened? The bytenft processor is used by a lot of companies Ive purchased from in the past so not surprising but if theres something else going on Id like to know because I give them a good amount of business and have never had any issues at all.

Puratek has always been very very good to me. Their payment system is a bit wonky but Wert*ByteNFT is correct and is what they're using.

@Stan-Douglas search your email for "Randy Went Undercover + Early 4th of July Deals" You should have it might be in a promotions tab.

Check out the vendor directory, there are some good options (Nexaph, Ezpeptides, Mile High, Glacier, etc) Just do your research diligence and see what works for you. There's several reviews and several post regarding success and options found. You just have to start somewhere.

@Stevepep said: @montemontemayor love it!! I now label how much bac I used so when I titrate I remember Prob a good idea too. I have that in a separate spreadsheet

I would do the Tesamorelin and Ipamorelin (that is what I do) As far as pens go, get good quality, not Amazon, Etsy, eBay, etc.. crap. I would definitely get at least 1 auto pen (lGansulin/Convi), they work great for hard to reach places (like sub-q in glutes) and a high quality manual pen. Novo, xulin, or a real v1 (if you can find one). Novo are the hardest when you are new, it doesn’t work straight out of the box… You will need at least 1 pen for every peptide you are going to take…
