Happy Friday, Friends! 👋
Busy week in the free community: 93 new posts and over 1,300 comments, and that is before the counting game giveaway went nuclear. First though, something happening tomorrow: Nikola and Jennifer are hosting a Psychedelics 101 Q&A inside the Membership, and there is a one minute video below of what those guest sessions actually look like. Then: the shoulder thread that pulled 53 replies, the honest conversation about what weight loss does to your backside, the one where a lot of you quietly stopped drinking, and four questions that kept coming back. Plus a heads-up on Agelixir stock at the bottom. My own posts are left out on purpose. Let's get into it.

🍄 Tomorrow: Psychedelics 101, Live in the Membership
Short notice on purpose, because it is tomorrow, Saturday September 26. Nikola and Jennifer are hosting a Psychedelics 101 Q&A inside the Exploring Peptides Membership. Bring questions, that is the entire format.
We have started bringing guests into the Membership to make it a fuller experience, and it has gone deeper than I expected. Menopause and hormone specialists, hypnobreathwork, and now this. Here is a one minute look at what those rooms are actually like.
🎙️ Before you join us
When: tomorrow, Saturday September 26. Where: inside the Membership group, where the time and the joining details are posted.
This is an educational conversation, not medical advice and not a how-to. Psychedelics are controlled substances in most countries. Nothing in the session is a protocol, a source, or a suggestion to go and use anything, and you should talk to your own doctor before making decisions about your health.
🔁 Did You Miss This? The 5 Threads That Got the Group Talking
Ranked by how much you all liked and commented, not by me.
1. "Six weeks in and my shoulder is better, but not fixed. Do I go up, or keep going?"
Julie has a chronic shoulder that got better on Wolverine and then stalled, and 53 of you showed up. The most useful answers were not "take more". BPC-157 has a very short half life, so splitting it into a morning and a midday dose does more than raising a single one. Others pointed at the blend itself (is it a 50/10/10/10 KLOW or something thinner), at adding a GH secretagogue to speed the repair side, and at getting hormones checked before blaming the peptide. One member shared a torn rotator cuff that recovered enough that her surgeon had no explanation. Six weeks is not always long enough. Neither is guessing.
2. "Can we talk about the reality of weight loss? Where did my butt go?"
Jessica asked the question everyone thinks and nobody posts, and 38 of you answered with zero embarrassment. The interesting part: not one useful answer was a peptide. It was hip thrusts, Romanian deadlifts, lunges, cable kickbacks, hyperextensions and resistance bands. Cindy put it best, get in the gym ladies. Heather admitted sitting on hard chairs now hurts. This is the conversation that makes the group worth being in, and it is a reminder that the stuff peptides cannot do for you is still the stuff that decides how you look at the end.
3. "Did your GLP-1 make you stop wanting alcohol?"
Tim asked specifically about desire, not about getting sick, and the answers came in fast. "The alcohol noise went quiet." That phrase came up again and again, and if you have been in here a while you will recognise it, because it is the same language people use about food noise. Members described the pull simply not being there anymore, some within weeks of starting. One says it is the reason 16 months of weight loss actually worked. Nobody set out to quit drinking. It just stopped being interesting.
4. Epithalon had a week (three threads, one lesson)
Barb asked how people dose it for sleep. Suzanne posted that 2 mg left her tired and cranky all day, went down to 1 mg and felt fine the next morning, and separately reported her HRV going from the 20s into the 50s. Across all three threads the doses people actually use ran from 100 mcg to 1 mg at night, and the ones getting the best sleep were mostly at the bottom of that range. If a compound is making you feel worse, the first move is down, not out.
5. "What is the starting dose of GHK-Cu for hair?"
Michelle asked, and the practical answers were about routine rather than milligrams. Serum at night, rinse it out in the morning, and if you use a red light helmet, use the light first and the serum after. Nobody wants to go to work with a copper serum in their hair, and that is the real reason people quit. There is a whole thread of tips in there, including what to stack it with and why before and after photos beat looking in the mirror.
Also worth a scroll:
💪 PEG-MGF, 31 comments. Post-workout timing, 100 to 200 mcg, run it four weeks then off. Read the cautions in there too.
🥶 "I lost the weight and now I am freezing all the time." Two answers: your body adjusts, and check your thyroid.
🏛️ The peptide vs government rant. What happens to research-only access if BPC and TB-500 get approved. Strong opinions, and a useful "let us not panic" reply.
🩸 How bad is an ApoB of 125? Calcium score vs CT angiography, and a spirited statin debate. Take that one to your own doctor.
♀️ The Menopause tab is open and so is the Book Club. You asked, they exist, go use them.

❓ Best Questions of the Week, Answered
These came up more than once, so they get a proper answer here.
"Why does GHK-Cu sting so much, and how much water should I use?"
Reynier had a pin that hurt for hours. Ted asked what to put in a 50 mg vial. Others have been quietly suffering through it. GHK-Cu is a spicy one, and almost every sting complaint comes down to too little water.
Hyperdilute it. The number that gets repeated in the group is 10 mL of bac water per 100 mg, so 5 mL for a 50 mg vial. Yes, that feels like a lot of water. That is the point.
Dose lower than you think. Most people sit at 1 to 2 mg, 5 days on 2 days off, roughly 6 weeks on and 4 weeks off. Sting reports go up sharply above that.
Two tricks from the group: draw a little extra bac water into the syringe after your dose, or draw a small amount of BPC after it. Both soften the burn.
Rotate, and warm it. Straight from the fridge into the skin is its own kind of unpleasant.
There is a GHK-Cu tips guide in the classroom with more. And if a site turns into a welt, a bruise or anything infected, that is not "spicy", that is a reaction, stop and get it looked at.
"What do I actually do with my used syringes?"
Stephanie has two plastic bottles full and no idea, which means a lot of you do too. Three real answers came out of that thread: needle clipper devices that snip the needle so the barrel can go in the regular trash (one holds 400 to 600 needles), safeneedledisposal.org, which lists the rules state by state, and in some places your local fire department will take a proper sharps container. What you should not do is put loose needles in a bin someone else has to empty.
"Which peptides do not take plain bac water?"
Miriam asked it twice this week, and it is the question that saves vials. Plain bacteriostatic water is the default, not the rule.
Ara-290 is the one that started it. It can gel in plain bac water, which is why you will see people reaching for phosphate buffered saline (PBS). Worth knowing though: Skye's Ara-290 has not had that problem, because it arrives already buffered, and the members running the current batch are mixing it with plain bac water and getting on with their day.
AOD-9604 usually wants acetic acid unless your vendor pH adjusted it first. Evita found hers still thickening in the fridge and going back to liquid at room temperature.
Which is the whole sourcing argument, sitting in one vial. Two people order the same three letters and have completely different mornings, because purity, buffering and pH were decided in a lab long before it ever reached your fridge. Real chemists with real credentials and real QC produce something a bargain-bin operation cannot, and you are the one who finds out which you paid for.
Anything you have not mixed before: check the vendor page or the classroom first. Five minutes of reading beats a gelled vial.
And when the numbers stop making sense, the calculator does not care what time it is.
"Why not just run Reta and Tirz together?"
Karen asked, Gil asked the sema version of it, and it comes up most weeks now. The answer in here is still no. There is no research behind the combination, and the reason people reach for it is usually appetite, which has a better fix: a small amount of Cagrilintide pinned about 3 days away from the Reta dose. Jamey's explainer on why Reta is not Tirz 2.0 is the best thing written on this anywhere, and it was the top thread in last week's recap for a reason.

📈 What Everyone Was Talking About
Out of 82 member posts this week:
GLP-1 practice was about 1 in 4. Reta or Tirz, combining them, Cagri on its own, transitioning between them, restarting after goal weight, food noise coming back, and two separate threads about vision-loss headlines on the news.
Reconstitution and solvents came second. GHK-Cu, Ara-290 and PBS, AOD gelling, B12, click pens and insulin pens, and one vial that got 2.5 mL instead of 1.
Healing and pain: the shoulder thread, torn tendons, migraines, a shingles vaccine question, and one member who stepped on a scorpion. Arizona sounds great.
Skin and hair: GHK-Cu for hair, GHK basic vs GHK-Cu (they are not the same thing), AHK-Cu with microneedling, and the sting thread.
Sleep and bioregulators: Epithalon in three threads, DSIP, and whether Epithalon and KLOW can share a bedtime.
Labs and hormones: ApoB, thyroid and gut, bloodwork moving around while things settle, estradiol patch brands, and the freezing cold thread.
Christiane answered 206 of your comments this week, her biggest yet, and Cindy was right behind her with 124. Loretta, Heather, Tim and Sue carried a lot of the rest. This group answers itself now, which is exactly what I hoped for. 🙏
🧪 EP Basics: Pre-Filling Syringes, Traveling, and Sharps
Week three of the rotating block. We did reconstitution, then storage, so this week is the part that happens on a Sunday night and in an airport. Mechanical only, not a dosing guide. (Not advice, just how it is done.)
Part 1: Pre-filling for the week
Draw them the way you always draw them. Swab, push air in, invert, pull to your units, tap out the bubbles. Nothing changes because you are doing seven at once.
Cap each one immediately and lay them in a small container rather than loose in a drawer.
Label the container, not the barrel: what is in them, the date you filled them, and the units. Barrel labels smudge.
Back in the fridge, dark and upright. Pre-filled syringes are a convenience for days, not a storage method for weeks.
One peptide per batch. Do not pre-fill three different things into identical syringes and trust Thursday-you to remember which is which.
Part 2: Traveling
Everything goes in one bag, and that bag is carry-on. Checked luggage gets hot, cold, and lost.
An insulin travel case with frozen gel packs is the setup most members use. Freeze the packs solid, because a half-melted one reads as a liquid at security.
It is medicine. That is the whole sentence. Most members report never being asked, and vials plus syringes in an obvious medical case are unremarkable.
Going somewhere hot? The cooler matters more than the case. A day at 30 degrees in a car does more damage than the flight.
Crossing borders, check the destination country's rules before you pack. Research compounds are not treated the same everywhere.
Part 3: Sharps, because you asked this week
A proper sharps container or a needle clipper. Clippers snip the needle off so the barrel becomes ordinary plastic waste.
Never recap a used needle by holding the cap in your fingers. That is how people get stuck.
Check your local rules at safeneedledisposal.org. Pharmacies, fire departments and household hazardous waste days all accept them somewhere.
Never loose in a household bin. Someone empties that bag.

⏰ Before You Go
🦄 Agelixir: under 100 bottles left, and a restock delay
Straight with you, because I would rather you hear it from me than find an empty page. We are down to under 100 bottles of Agelixir, and the restock is running behind. We are hoping to have it back toward the end of October. If it is part of your routine and you are getting low, top up now rather than in three weeks. If we sell out before the restock lands, that is the gap, and I will tell you the moment it is back.
Cindy posted her own two and a half week review in the group this week, video and all, if you want to hear it from someone who is not me.
No other live sale this week. 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. Three 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, especially with pre-filling and travel being the Basics topic this week:
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! ❄️
