Happy Friday, Friends! 👋
Busy week in the free community: 77 new posts and over 1,000 comments. The big one is actual news, a real U.S. trial for injectable BPC-157, so that goes first. Right behind it, The Daily Peptide app just got a big upgrade: snap a photo of your plate instead of typing it, and finally keep track of every vial in your fridge. Then: the SS-31 dose argument that pulled 59 replies and brought out both me and Jennifer, a hard look at Mots-c reactions, three people asking whether their vial had gone wrong, and the foot peel thread that got genuinely funny. My own posts are left out of the rankings on purpose. Let's get into it.

🔬 Finally: a Real U.S. Trial for Injectable BPC-157
This is the post that got the biggest reaction of the week, 130 likes, and it deserves it. The University of Arkansas has launched the first U.S. based randomized controlled trial of injectable BPC-157 for tissue healing.
What it actually is
What they are measuring: healing after rotator cuff surgery, through objective measures. Strength testing, MRI, range of motion, plus patient reported outcomes.
Why that matters: this is the thing the science community and physicians have been asking for. Not a survey, not anecdote, not a rat study. Objective measures in humans.
Now the patience part. Enrollment starts early 2027. First data likely early 2028. So nothing changes for you this year. There are also several other studies underway in other countries.
Honestly, I did not think this would happen. Hopefully we finally get some good data. 🤓
The top comment in that thread was simply "And, the prices go up." You are not wrong to think it. We talked about exactly that when the FDA conversation came up a couple of weeks ago.
📱 The Daily Peptide App Just Got a Serious Upgrade
If you use The Daily Peptide, you will get an update popup this week. Take it. This one is a big one, and the short version is less typing, more knowing. Point your camera at your plate or your scale and the app does the boring part for you.

🔁 Did You Miss This? The 5 Threads That Got the Group Talking
Ranked by how many of you jumped into the comments, not by me.
1. "40 mg a day is the approved dose. So why is almost everyone using a fraction of that?"
Tim asked the best question of the week and 59 of you piled in. He noticed that 40 mg per day is the FDA approved dose for elamipretide and the dose used in most of the human studies, while the community mostly runs far less. So is the low dose doing anything at all? Both Jennifer and I ended up in there. My read: the high doses in the literature are for serious chronic conditions, so for general wellness it makes sense to find the minimum effective dose rather than copy a disease protocol. Jennifer doses by body weight instead of a flat number. Christiane dropped a study using 4 mg a day for 28 days. Read the whole thing, it is the most useful dosing conversation we have had in a while.
2. An integrative OBGYN on what goes alongside hormone therapy
Christiane shared a talk by Dr Felice Gersh on adjunct supplements for women going through hormone changes, and it became the most liked thread of the week with 46 comments. The appeal was that it is practical rather than ideological, and more than one person said it made them rethink how HRT is usually done. Worth noting Christiane was clear she is not endorsing the specific brands mentioned in the video. The conversation underneath about NMN forms, powder versus liposomal versus sublingual, is as useful as the video.
3. Mots-c had a week: "any real world bad reactions?"
Jeff asked plainly for the bad experiences, and he got them, including his own. He had a large painful itchy site reaction, diluted a fresh vial right down, tried the other hip the next day, got the same thing, and has stopped. That is a useful data point and it deserves to be said out loud, because not every peptide suits every person. Others are running it with no trouble: Brandon starts low, uses a half inch pin, brings it to room temperature and injects slowly. Christiane noted others here have had the same reaction or full hives, and that SLU-PP can stand in. Meanwhile Kimberly ran the friendlier version of the question, Mots-c or NAD+ for energy, and got 22 answers split fairly evenly.
4. "I applied the booties. I am more than a little terrified."
Jason did a Baby Foot peel while watching football and live-posted his fear, and the group delivered. Heather's warning is the stuff of legend: be prepared for sheets of dead skin, everywhere, for about a week. No flip flops. Check your sheets. Someone described it as disgusting and then immediately said they were going to try it. This is not a peptide thread and it does not need to be. It is the reason this group is a nice place to spend time.
5. "Is my glutathione supposed to have strands floating in it?"
Jose reconstituted a 1500 mg vial and found what looked like clear strands, and asked before throwing it away. Good instinct, because it was not spoiled, it was under-diluted. Glutathione has real solubility problems and wants roughly 1 mL of bac water per 200 mg. He added more, got to 7.5 mL, and it cleared completely. First time reconstituting, problem solved in one thread. That is the whole point of this place.
Also worth a scroll:
🦶 What is the starting dose of ARA-290 for neuropathy? One member used 4 mg five days a week for eight weeks and said it took a full month to notice anything.
😮💨 "I am struggling with extreme fatigue." Loretta laid out her whole stack and asked the group to find the flaw. The most useful reply was about hormones, not peptides.
⚖️ A month-long stall, and what to do about it. Best answer in there: five questions to ask yourself before you raise a dose. Also a reminder that the scale is not the only metric.
🫙 GLP-1s and the gallbladder. A real contraindication conversation, including what to do if yours is already gone. Take it to your own provider.
✈️ Two weeks in Europe with Reta and no fridge. Follows nicely from the travel basics a couple of issues back.

🦄 Agelixir Is Sold Out (Here Is How to Use Yours)
Quick news first: Agelixir is completely sold out. Every bottle is gone, and we are working hard on a restock for the end of November. Thank you, honestly, it went faster than I expected. Want one from the next batch? Tap the bottle below and hit "Notify me when back in stock" on the product page, and you will be the first to get an email the moment it is back.
If you got one, this part is for you. Erika posted her full routine this week and asked whether she had it right, and it turned into 19 comments of genuinely good skincare sequencing.
The two things worth knowing
Go carefully near the eyes. The GHK-Cu is the reason. Some members use it on the upper lid away from the lash line and are fine, others avoid the lids completely. Christiane got it in one eye once and it took hours to settle. If your eyes are sensitive, stay off the lids.
Give it longer than you think. The usual report is noticeable change at four to six weeks and fuller effect by around three months. Cindy posted a four week progress photo this week and said the real change was skin texture rather than any one line.
❓ Best Questions of the Week, Answered
These came up more than once, so they get a proper answer here.
"Is my vial supposed to look like that?"
Three separate versions of this in one week, so here is the short decision tree. Cloudy or stranded is usually a dilution problem. A colour change is usually not.
Strands or haze in glutathione: almost always not enough water. It needs about 1 mL per 200 mg, which is a lot more than people expect. Add more and watch it clear.
A yellow or gold tint where there should be none: do not use it. Photograph it and ask the seller for a replacement. Any seller worth buying from will replace it without an argument.
The stopper came away and the vial was open to air: that one is a contamination call, not a cosmetic one, and the cautious answer is the right answer.
Before you mix anything new, check what it actually needs. Some things want more water than you think, some want a different solvent entirely.
"Tesamorelin, CJC with Ipamorelin, Sermorelin. Can I stack them or swap them?"
Three people asked a version of this. The key idea: Tesamorelin, Sermorelin and CJC no DAC are all the same class, so stacking two of them is not the move. The pairing that makes sense is one of those with a GHRP like Ipamorelin. Sermorelin pairs with Ipamorelin, and Tesamorelin pairs with Ipamorelin at roughly 1 mg to 200 mcg. For CJC no DAC the ranges members use are 100 to 300 mcg with 200 to 300 mcg Ipamorelin, starting at the bottom to see how you respond. Swapping to finish a vial you already own for a month is not a problem. And if you are doing this for body composition, get an IGF-1 level first, because if you are already mid-range for your age you may not get much.
"Where do I even buy this one?"
SS-31, Pinealon, Humanin, L-glutathione, methylene blue, plus two straight "who do you trust" posts. The honest answer is that we deliberately have very few vetted sellers, and that is the point. We only work with vendors vialing and lyophilising in U.S. cGMP facilities, because when the vendor controls the batch stateside the certificate of analysis actually describes the vial in your hand. Quality over quantity, always has been. For the harder to find ones like SS-31, email Skye customer service and ask about the offline catalogue. Everything else, including codes, lives on the resource page.
"Can I take this with my medication?"
Five threads this week: prednisone, a blood thinner, milk thistle, a gallbladder question, and whether to keep injecting through a cold. I am going to be boring on purpose here, because this is the one category where the group genuinely cannot answer for you. Interactions depend on your medication, your dose, your condition and your labs, and none of us can see those. The group is excellent for what members experienced. It is not a substitute for the person who can see your chart. Ask them, and if they do not know peptides, ask a practitioner who does.

📈 What Everyone Was Talking About
Out of 68 member posts this week:
The mitochondrial stack was the biggest cluster. SS-31 dosing, SS-31 sourcing, Mots-c reactions, Mots-c versus NAD+, Humanin, and where the whole protocol fits together.
GH secretagogues came second. Tesamorelin versus CJC and Ipamorelin, adding Sermorelin, and whether the pair is worth it for women on a low Reta dose.
"Is this vial OK?" Glutathione twice, a tinted KPV, an exposed GLP-1 stopper, a 5-amino and an HGH reconstitution question, and someone asking whether an injectable can be turned into a nasal spray.
Labs and deficiencies. Ferritin at 6, two iron threads, cortisol after a bereavement, a dropping EGFR, and liver questions. More of you are testing, which is good.
Meds and conditions. The five interaction threads above, plus lupus, MCAS and fibromyalgia.
Skin. Agelixir routines, a DIY GHK-Cu serum with storage questions, and the foot peel.
Christiane answered 214 of your comments this week, which is another personal record, and Heather was right behind with 81. Loretta, Cindy, Philip, Erika and Tim carried a lot of the rest, and Jennifer came over to the free side for the SS-31 thread. This group answers itself now, which is exactly what I hoped for. 🙏
🧪 EP Basics: Injection Sites, Rotation, and Making It Hurt Less
Week four of the rotating block, and this week it writes itself, because half the threads above were site reactions. Mechanical only, no dosing. (Not advice, just how it is done.)
Part 1: Where it goes
Subcutaneous means into the fat layer, not into muscle. Belly a couple of inches away from the navel, outer upper thigh, the back of the upper arm, the upper outer buttock. Pinch, go in, push slowly.
Short needle, shallow angle. Most members use a half inch insulin syringe. Longer needles are how you end up intramuscular by accident, which stings more and absorbs differently.
Do not reuse yesterday's spot. Pick a rotation and stick to it, left and right, high and low. Repeatedly pinning one square inch is how you get lumps that take weeks to settle.
Part 2: Why it stings, and what helps
Cold is the most common cause. Straight from the fridge into skin is unpleasant on its own. Let it sit out for a few minutes first.
Too little water is the second. A more dilute vial is a more comfortable injection, and for the famously spicy ones that is the whole fix.
Push slowly. Volume going in fast is its own kind of ache. Count it out.
Let the alcohol dry. Pinning through a wet swab stings and people blame the peptide.
Two tricks from the group: draw a little extra bac water after your dose so the last of it goes in diluted, and some members spray the site with a steroid nasal spray after swabbing, letting it dry before pinning, to calm the local histamine response.
Part 3: Know the difference between spicy and wrong
Normal: a sting during or just after, mild redness, a small bump that fades within the hour.
Not normal: a large raised welt, spreading itch, hives, something that lasts for days, anything that looks infected, or anything involving your breathing.
If it keeps happening with one specific compound, that is information. Diluting further and moving sites is a fair test. If it reacts twice on two different sites, it may just not be for you, and that is allowed.
Anything systemic or spreading is a doctor question, today. Not a forum question.

⏰ Before You Go
No live vendor sale this week, the Scantifix competition closed on September 30th and I will announce the winner in the group. Same codes as always: Skye code Exploringpeptides, Scantifix code Exploringpeptides (15% there too), Limitless code EP20, and for Canada BioSlab code EP10.
And if this recap was useful, hit reply and tell me. If a thread you loved got left out, tell me that too. Four issues in and I am still shaping this around what you actually read.
❄️ My Long-Term Storage Approach
(Not advice, just my own system for research peps.) I've shared this before, but it's worth revisiting:
2 to 4 × HydraPeak 32oz thermoses with peptide inserts
2 to 3 of them for freezer storage (1 to 3 years)
One for fridge storage (6 to 12 months)
Everything labeled, rotated, and calmly managed
I use a Dymo labeler, but tons of labeling machines work great for this. You can also just use a pen and mark the sticker on the vial. Anxiety-free prep! ❄️
