@bobs So they are Nexaph but a lot more expensive? For what exactly? I noticed even Peptidology nowadays displays cGMP on their site. Not sure what that means exactly. Should ping Josh, the owner. He's the nicest vendor I have seen.

@mrjoshua44 Whatever works my man, I haven't seen over 5 after 8 weeks. I just asked petidefox AI lol. It said to back off to 6mg 2 to 3x per week or 2mg a day. Like I say, though, you can try titrating down maybe a MG and see if you feel any change; if you do, titrate back up. It can get expensive at these dosages. I just went to 3x per week for motsc, and I like it. I was using it every day, 3 mg a day, so 21 a week, and just went to 5mg 3x a week, and I feel better so far. You never know. I am really liking peptidefox and I am skeptical of these types of websites after spending some time in e-commerce, many times, these are funnels for retailers. Great find!!!!

This is a vendor review submitted by mrjoshua44 on PeptideCritic.com. Rating: (4/5) Review I would give the 5 stars if the prices weren't so high for the SS-31 50mg vials. But the quality is excellent and always seems to be shipped on the same day of order. I'm a repeat customer and will continue to purchase from them.

@Stan-Douglas Right on. I was doing some reading about that one just trying to learn more about which peptides I can and cannot take while I still have this benign Schwannoma tumor in my neck. I read that one of the trials went as long as twelve weeks, but of the four studies I found most were 28 days and was noted to have persistent benefits after the cycle has stopped. So hopefully you'll start to see some improvement with your symptoms.

And it turned to jello so I have my answer ughhh

Anyone have any experience with these guys….given some the questions raised about testing companies lately…these guys seem to go mostly with Janoshik and have time do purity, heavy metals, endotoxins, etc.

This is a vendor review submitted by Eleanor on PeptideCritic.com. Rating: (5/5) Review Outstanding sale on items I wanted. Can't account for their regular pricing, but will shop them first at every sale! My order came in a regular Fed Ex which I winced at first, then found a 'bulk' wrapped in a bit thicker padded white envelope and when I opened it, found a small, tupperware-like container with a white lid; 2" x 2.5" and I was impressed! But wait, there's more... On each SS-31 vial, the label has the production date, CAS#, batch #, exact mg., purity, corresponding cap color, & QR code, all on the vial label according to their COA; much like the NAD+ buf 1062.77mg. How handy this is! I'm really anxious to try their products out but am taking them in order of production date, so when I do try them, I'll post the results. Barring results, I'M SOLD!

@Stan-Douglas said: @AllisonW I accidentally bought 2 kits instead of 1 a couple weeks ago and just got an email that a third kit, that I had bought to test a third site, is on the way. All of them are 50mg a vial! NICE!

I take my SS-31 daily with my Xulin 3. I use pens for peptides I research with daily or at least multiple times a week. That's where the efficiency really helps. You are taking a much high dose than I am, so I can't attest to the stinging. I'm using 4mg/day in preparation for a MOTS-C cycle. I might bump it up to 6mg/daily. I felt like the doses in the 20-40mg range were more aligned to the study for Barth Syndrome for major mitochondrial disfunction. My goals are more athletic recovery, performance, and healthy aging. Good luck!

@gym.rat I did read the full write up but have a question regarding sequence. Am posting a separate thread on this and appreciate yours and everyone's knowledge on this.

@stan-douglas or just get a crypt exchange account and a kewl wallet like Tangem and self custody. However you can get use software wallets too.

Dang, sorry i missed this one. Would love to hear how it goes once you get your results. Im still on the hunt for some SS-31 at a reasonable price.
