I have seen a lot of people posting about the success or nasal delivery for Semax and Selank. This has intrigued me for to the fact that I love the idea of these compounds yet haven’t had the best of luck with them. Then I started seeing advertisements for NAD and and BPC157 using this method as a delivery vehicle. So… I started digging, bought some saline, some bottles, and dug out my Selank. So far I have made a Selank and a NAD nasal spray. I am about a week into my research, so things are still early. I really love the thought using a compound without the need to inject it. The Selank makes since due to the neurological effect being delivered to the blood stream so close to the target area. Since NAD is a systemic compound, I don’t believe it is hurting anything to use this delivery method. The only concerning thing to me is the fact that I am not getting the quantity of NAD with this delivery method and will take time, patience, practice to get the adjustment pinned down. I would like to hear what you think about the subject, have you tried this, where have you seen the benefits?

Most of us who have spent time researching mitochondrial health eventually run across two familiar names: SS-31 MOTS-c I've discussed both quite a bit. But recently I listened to Alex Kikel speak at a peptide conference, and he mentioned two compounds that immediately caught my attention: HDAP2 — as a possible next-generation alternative to SS-31. Mitochonic Acid — as something we may eventually hear discussed alongside, or potentially instead of, MOTS-c. So naturally, I was more than curious and started digging. I’d never heard of either and found there is actually quite a bit going on here. 🔥 HDAP2 — WHAT COMES AFTER SS-31? One of the primary jobs of SS-31 is helping protect and stabilize the inner membrane of our mitochondria. Think of that membrane as part of the machinery that allows the mitochondria to efficiently produce energy. When it becomes damaged or unstable, mitochondrial performance suffers. HDAP2 is being researched as another way of protecting and stabilizing that same critical mitochondrial structure. But this isn't just a molecule someone recently dreamed up. Researchers have already moved into animal studies. HDAP2 has been given systemically to mice and has demonstrated the ability to actually reach mitochondria in the targeted tissue. In models involving mitochondrial damage, researchers have reported: → better mitochondrial preservation → less cellular damage → improved cell survival → protection of mitochondrial function under stress One recent study involving damaged optic nerves was particularly interesting. Animals receiving HDAP2 retained dramatically more mitochondria in the injured nerves than untreated animals. Tells me there's enough here to keep watching. ⚡ MITOCHONIC ACID — THIS ONE REALLY GOT MY ATTENTION The second compound Kikel mentioned was Mitochonic Acid. Technically, this isn't a peptide at all. But forget the chemistry for a minute. What matters is what researchers are trying to accomplish with it. Mitochondria have an incredibly organized internal structure. Those little folds you've probably seen in every drawing of a mitochondrion aren't there by accident. They're where much of our cellular energy production takes place.

INJECTABLE DELIVERY & THE “ONE-SYRINGE” QUESTION We've looked at what glutathione is, what happens when we take it orally, and what liposomal delivery may—and may not—improve. Now we get to the final piece: Injectable glutathione—and the practice of combining it with Vitamin C. The attraction to injectable glutathione is pretty obvious. We remove the digestive system from the equation and deliver glutathione directly into the body. But then comes the next question: If glutathione and Vitamin C work together biologically, why not put them together in the same syringe? That's where things get interesting. 🧬 WHY GLUTATHIONE + VITAMIN C? There is legitimate biology behind pairing them. Glutathione and Vitamin C are both part of our interconnected antioxidant/redox system. They perform different jobs, but they can support one another in helping the body manage oxidative stress. So, using both can make sense. But there are actually two completely different questions: Do Glutathione and Vitamin C complement one another biologically? Can injectable Glutathione and Vitamin C simply be mixed together in the same syringe? 🍋 THE ACID PROBLEM Vitamin C in its basic form is ascorbic acid. An unbuffered ascorbic-acid solution can fall roughly into the pH 2–3 range, depending upon concentration. Inject something that acidic directly into muscle tissue and you're probably going to know it: Burning. Stinging. Pain. Irritation. And at sufficient extremes, highly acidic solutions can actually injure tissue. This is why the formulation of injectable Vitamin C matters. 🧪 PHARMACEUTICAL FORMULATION CHANGES THE STORY Pharmaceutical injectable Vitamin C can be pH-adjusted to reduce the acidity problem. But fixing the pH doesn't automatically make every concentrated Vitamin C product appropriate for a direct IM injection. Some concentrated pharmaceutical Vitamin C products are specifically designed to be diluted into an IV solution before administration. That's an important distinction: "Injectable” doesn't automatically mean “ready to inject into muscle.”

THE DELIVERY PROBLEM Now we get into the part that probably matters most to anyone actually considering glutathione: How do we get more of it into the body? There are several different approaches, and they are often discussed as though they're interchangeable. They're not. 🔬 APPROACH #1 — PRECURSORS One approach is to give the body more of the raw materials it needs to manufacture its own glutathione. This is where NAC (N-acetylcysteine) and glycine come into the discussion. NAC supplies cysteine, while glycine supplies another of the amino acids required for glutathione production. The strategy is straightforward: Provide more of the necessary building materials → let the body manufacture more glutathione itself. You're not actually taking glutathione. You're trying to increase the body's ability to make it. 💊 APPROACH #2 — STANDARD ORAL GLUTATHIONE The second approach seems even simpler: Take glutathione itself. But now we run directly into the digestive system. When we swallow something, it doesn't simply travel from our mouth directly into our bloodstream. It has to survive the stomach, digestive enzymes and the intestinal environment before it can be absorbed. And glutathione is a tripeptide. Our digestive system is specifically designed to break peptides and proteins down into smaller components. So the question with standard oral glutathione becomes: How much of what I swallow actually survives the process and becomes available to the body? 📊 ABSORPTION vs. BIOAVAILABILITY These two terms are frequently treated as though they mean the same thing. They don't. Absorption refers to a substance crossing from the digestive tract into the body. Bioavailability refers to how much of the administered compound actually becomes available to circulation in a usable form. That's why the number printed on the front of a supplement bottle doesn't necessarily tell us how much we're actually getting. Taking 500 mg does not automatically mean 500 mg becomes biologically available.

THE “MASTER ANTIOXIDANT” AND WHAT HAPPENS AS WE AGE If you've spent any time in the peptide, biohacking or longevity space, you've probably heard Glutathione referred to as the “Master Antioxidant.” But what exactly is glutathione? What does it actually do? And why does it become increasingly important as we get older? Before we get into supplements, liposomal delivery, injections—or eventually combining glutathione with things like Vitamin C—we need to understand the molecule itself. 🔬 WHAT IS GLUTATHIONE? Glutathione isn't something foreign that we're introducing into the body. Your body already makes it. Glutathione is a small molecule called a tripeptide, which simply means it is made from three amino acids: Glutamate + Cysteine + Glycine = Glutathione It is found throughout the body and particularly inside our cells. One of its most important jobs is helping our cells control something we hear about constantly but rarely stop to define: Oxidative stress. ⚡ WHAT IS OXIDATIVE STRESS? Every cell in our body is constantly carrying out chemical reactions. We convert food into energy. Our mitochondria produce ATP. Our immune system responds to threats. Our liver processes compounds. Our cells communicate with one another. During normal metabolism, the body also produces highly reactive molecules, including what are called Reactive Oxygen Species—or ROS. ROS are not automatically bad. In controlled amounts, the body actually uses them for things like cellular signaling and immune function. The problem is when the production of these reactive molecules begins to overwhelm the body's ability to control them, we develop: OXIDATIVE STRESS And excessive oxidative stress can damage proteins, fats, DNA and other cellular structures. This is where glutathione becomes important. When you research glutathione, you're going to repeatedly see terms such as redox, oxidation and reduction. They sound complicated, but the basic concept isn't. ⚖️ WHAT DOES “REDOX” MEAN? REDOX = REDuction + OXidation - At its simplest, redox describes the movement of tiny negatively charged particles called electrons between molecules.
