Master Peptide Cheat Sheet

Selank is a lab-made peptide that can help calm anxiety and sharpen focus and memory, usually taken as a nasal spray. It doesn't make you drowsy and isn't habit-forming.

P21 is a lab-made peptide that may help brain cells grow and support memory, without the side effects of the natural hormone it's based on. People usually take it as a nasal spray or a small injection under the skin.

Thymulin is a natural hormone that helps train immune cells and may calm inflammation and slow some effects of aging on the immune system. It needs zinc to work properly, and people use it to support immune health, especially as they get older.

Cerebrolysin is a mix of nutrients extracted from pig brain tissue that supports brain cell growth and repair. Doctors use it to help people recover from strokes, dementia, and brain injuries, and some people use it off-label to sharpen thinking and support brain health.

AHK-Cu is a copper-containing peptide that helps skin make more collagen and can encourage hair growth. It's used in creams and serums, not injections, mainly for anti-aging skincare and hair thinning.

Crystagen is a very short peptide meant to support brain and nervous system health. It's taken in short cycles and may help protect brain cells and support memory as you age.

Cortagen is a short peptide designed to support brain function by helping neurons build the proteins they need to work well. People take it in short courses to support memory, focus, and brain protection.

This is a blend of four brain-focused peptides (Semax, Selank, Pinealon, and PE-22-28) combined to support mood, memory, focus, and new brain cell growth. It comes as a nasal spray or injection, usually taken in the morning on an empty stomach, but there's no research yet on this exact four-peptide combination.

NA Semax Amidate is an improved, longer-lasting version of Semax that the body absorbs and holds onto better. People use it to think more clearly, protect the brain, boost a brain-growth hormone called BDNF, and ease anxiety, usually via injection or nasal spray.

Ovagen is a peptide made to support liver and digestive health. It's typically used in short cycles a few times a year and may help normalize liver enzymes and support gut repair.

Pinealon is a very short peptide studied for protecting brain cells and supporting memory. It may also help reduce stress-related damage in the brain and support your body's natural sleep-wake cycle, and it's usually taken in short cycles.

SNAP-8 is a topical peptide used in anti-wrinkle creams. It works by relaxing the tiny facial muscles that cause expression lines, and it's stronger than the similar ingredient Argireline.

Survodutide is an experimental weekly injection being studied for weight loss. It works by curbing appetite and boosting the number of calories your body burns, and early studies show it also helps with a liver condition called MASH.

Thymogen is a very small peptide that helps the immune system mature and work better. It's used to support immune recovery, especially when someone's immune system is weakened, and is also studied for anti-aging benefits.

Semax is a well-known Russian peptide that boosts brain chemicals (BDNF and NGF) linked to memory, focus, and brain protection. It's usually taken as a nasal spray, either every day or on a 5-days-on, 2-days-off schedule.

L-Carnitine is a natural compound that helps your cells burn fat for energy and can support recovery after exercise. Injectable forms are popular because the body absorbs them better than carnitine taken by mouth.

Testagen is a very short peptide believed to support healthy testicular function and hormone balance in men. It's used in short cycles, often alongside other similar peptides, as part of longevity-focused routines.

BAM-15 is an experimental compound that helps the body burn fat without raising body temperature, which makes it safer than similar older compounds. Most of what we know comes from animal studies, not humans.

Adalank (NA-Selank Amidate) is a stabilized version of Selank designed to last longer in the body. People use it to ease anxiety and support focus and mood without feeling sedated or becoming dependent on it.

PNC-27 is an experimental peptide being studied for its ability to target and destroy cancer cells while leaving healthy cells alone. It's still in early research, so safe and effective human dosing isn't well established.

Mazdutide is an experimental injection being studied for weight loss and blood sugar control in type 2 diabetes. It works by curbing appetite and helping your body burn more energy.

Thymosin Beta-4 (also called TB-500) is a peptide that helps the body heal tissue faster, calm inflammation, and repair muscles, tendons, ligaments, and skin. It's popular for recovering from injuries and wounds.

PE-22-28 is an experimental peptide being studied as a fast-acting option for depression, anxiety, and brain protection. It's thought to work by boosting serotonin activity and encouraging new brain cell growth.

HCG is a hormone that tells the testicles to keep producing testosterone and stay their normal size. It's commonly used after steroid cycles or alongside testosterone therapy to protect fertility and prevent the testicles from shrinking.

Dihexa is a nootropic peptide that may help the brain form new connections between neurons, supporting memory and learning. It's typically taken orally or applied to the skin and is reported to be far more potent than the body's natural BDNF.

HMG is a fertility hormone that stimulates the testicles to produce sperm and testosterone. It's often used with HCG after a steroid cycle to help restore natural fertility and hormone production.

Livagen is a short peptide studied for helping cells 'turn back on' genes related to immune and heart health, which may support longevity. It's used alongside other similar peptides to support immune function and slow age-related decline.

Vesilute is a peptide designed to support bladder health by helping the tissue lining the bladder repair itself. It's taken in short courses, similar to other Russian-developed peptides, and may aid recovery from urinary issues.

Cagrilintide mimics a natural hormone called amylin to help curb your appetite.

MOTS-c is a mitochondrial peptide studied for metabolic health and exercise capacity. Weekly totals of 5–10 mg are typical, split into two or three injections.

Hexarelin triggers a strong release of growth hormone, but the body gets used to it quickly, so its effects can fade with regular use. It's given as an injection under the skin.

SS-31 supports the mitochondria, the energy-producing parts of your cells.

This is Tirzepatide, a medication that activates two gut hormone pathways (GIP and GLP-1) to help with weight loss and blood sugar. Dosing starts at 2.5 mg once weekly for four weeks, then moves to 5 mg, and can rise in 2.5 mg steps every four weeks up to a maximum of 15 mg. Maintenance doses are 5, 10, or 15 mg weekly. Some people use very small 'microdoses' of 0.5 mg or less, or split the weekly dose into two injections, to reduce side effects. Splitting doses has shown to lower the peak blood level by roughly 28%, which is the usual explanation for less nausea.

BPC-157 is a peptide known for helping the body heal tissue faster.

Ipamorelin encourages your body to release its own growth hormone and tends to cause fewer side effects than similar peptides. It's usually injected at night on an empty stomach, since that's when the body's own growth hormone surge happens. Doses above 300 mcg don't produce proportionally more growth hormone, so 300 mcg per injection is the practical ceiling.

Cartalax is used to support joint health and help repair and regenerate cartilage.

VIP helps regulate inflammation in the body.

PEG-MGF supports muscle repair after a workout and is injected under the skin or into the muscle.

CJC-1295 with DAC is a long-acting peptide that keeps growth hormone levels steadily elevated over time.

DSIP is used to help improve deep, restorative sleep.

GHRP-6 triggers the release of growth hormone and also tends to increase appetite.

Epitalon may help activate an enzyme called telomerase, which is linked to cell aging, and is typically used in short cycles rather than continuously. A full cycle usually totals around 100 mg.

FOXO4-DRI is an experimental compound being studied for clearing out old, damaged 'senescent' cells. It's rare and expensive, and still not well understood.

GHK-Cu is a copper peptide that helps repair and regenerate skin and hair. Most protocols start at 1 mg daily for the first two weeks, then move up to 2 mg, with a 3 to 4 week break between cycles.

Glutathione is a powerful antioxidant that supports detoxification, helps calm inflammation, and can improve skin health. Keep the reconstituted vial refrigerated and protected from light, and use it within 2 to 3 weeks, since it breaks down faster than most peptides.

NAD+ is a molecule your cells need to produce energy. Most protocols start around 20 mg and build up toward 100 mg over several injections, since injecting too much too fast commonly causes flushing, nausea, or a wave-like sensation. Starting lower and titrating up reduces this.

Sermorelin encourages your body to release more of its own growth hormone. It's injected at night on an empty stomach, 30 to 60 minutes before bed, to line up with the body's natural overnight growth hormone release. Most protocols start at 200 to 300 mcg and increase by about 100 mcg every week or two.

Thymalin helps restore balance to the immune system and is given as an injection under the skin.

This is a combination of Tesamorelin and Ipamorelin that helps reduce belly fat while boosting your body's natural growth hormone release. Taken once daily in the evening on an empty stomach, since food blunts the growth hormone pulse. Because the two peptides are blended in equal amounts, the dose is capped by Ipamorelin, which stops producing more growth hormone above 300 mcg.

Vesugen is used to support healthy blood vessel function.

Vilon is a gentle immune-system support peptide given as an injection under the skin.

This combines BPC-157 and TB-500, two well-known healing peptides, to speed up tissue recovery from injuries. Doses are listed per peptide, so a 500 mcg dose means 500 mcg of each, or 1 mg total.

TB-500 helps regenerate tissue and reduce inflammation. The 4–6 week schedule is a loading phase; after that, protocols typically drop to 2–4 mg every one to two weeks for maintenance.

Melanotan II triggers your skin to tan and offers some protection from UV rays by activating a pigment-producing pathway. People typically use it daily until they reach the tan they want, then cut back to once or twice a week to maintain it. Nausea and flushing are common early on, so many start at 100 to 250 mcg for the first few days and inject before bed on an empty stomach.

Kisspeptin helps stimulate a hormone (GnRH) that plays a key role in fertility.

Thymosin Alpha 1 is often called the 'BPC-157 of the immune system' because it's so widely used to support healthy immune function.

Humanin helps protect cells, particularly by supporting healthy mitochondria.

KPV helps calm inflammation and supports gut repair, given as an injection under the skin. Usually taken in the morning.

Tesamorelin stimulates natural growth hormone release and is best known for reducing visceral (belly) fat and can improve overall metabolism. Injected before bed, at least two hours after the last meal.

MGF helps stimulate muscle repair after exercise and is injected under the skin or into the muscle.

This is Semaglutide, a long-acting medication that helps control appetite and blood sugar. Dosing starts at 0.25 mg once weekly and steps up every four weeks: 0.25 → 0.5 → 1 → 1.7 → 2.4 mg, with most people settling at 1.7 or 2.4 mg. It's also available as a ready-to-use pen that doesn't require mixing with water, and as a once-daily pill.

Melanotan I helps your skin tan and offers some UV protection, with fewer side effects than Melanotan II. People usually use it daily until they get the tan they want, then use it less often to maintain it.

PT-141 helps boost libido by acting on a pathway in the brain linked to sexual desire. Injected 45 minutes before anticipated activity, with effects starting in 45 to 90 minutes and lasting 4 to 8 hours. The FDA-approved dose is 1.75 mg, though many start at 500 mcg to gauge tolerance since nausea is the most common side effect.

This is Retatrutide, an experimental medication that activates three different gut hormone pathways at once. Doses are raised slowly over time, a process called titration, with each step held for four weeks. In the Phase 3 TRIUMPH trials, everyone starts at 2 mg per week and steps up from there: 2 → 4 → 6 → 9 → 12 mg. Earlier trials found that starting at 2 mg rather than 4 mg caused fewer stomach side effects while producing the same weight loss at 48 weeks. Some people take much smaller 'microdoses,' often around 0.5 mg per week, to reduce side effects further. Going up gradually matters because most side effects, especially nausea and other stomach issues, appear right after a dose increase rather than at a steady dose.

This blend combines GHK-Cu, BPC-157, and TB-500 to support skin health alongside general tissue repair. How much you take depends on the amount of GHK-Cu in the specific product. Target a total blend volume of 2.80 mg (2mg GHK-Cu, 400 mcg of BPC-157, and TB-500).

This blend combines GHK-Cu, KPV, BPC-157, and TB-500 to support skin health and general tissue repair. How much you take depends on the amount of GHK-Cu in the specific product. Target a total blend volume of 3.20 mg (2mg GHK-Cu, 400 mcg of KPV, BPC-157, and TB-500).

IGF-1 LR3 is an anabolic peptide that promotes muscle growth and is injected under the skin or into the muscle. Beginners usually start at 20 to 40 mcg.

5-Amino-1MQ supports mitochondrial function and can help with fat loss.

AOD-9604 is a small fragment of growth hormone that helps promote fat burning. It's injected in the morning on an empty stomach. It won't dissolve properly in plain bacteriostatic water and will cloud, flake, or gel at the bottom of the vial instead. Add a small amount of 0.6% acetic acid first and swirl until the solution turns clear, then top it up with bacteriostatic water, around 2 mL. If it has already gelled, adding the acid a few drops at a time will usually bring it back.

SLU-PP-332 is a lab-made compound (not technically a peptide) that helps boost mitochondrial function and endurance, and is used for fat loss. All the dosing data we have comes from mouse studies — there's no human safety data yet.

CJC-1295 and Ipamorelin work together to trigger a natural growth hormone pulse. Taken on an empty stomach before bed, with a break between cycles to keep the receptors responsive.

CJC-1295 without DAC is a shorter-acting peptide that triggers quick pulses of growth hormone release.

LL-37 has antimicrobial properties and supports healing, given as an injection under the skin.

Ara 290 may help repair nerves and reduce pain.

GHRP-2 triggers growth hormone release and causes less hunger than a similar peptide, GHRP-6.

Oxytocin, sometimes called the 'bonding hormone,' can enhance feelings of connection and intimacy.

This blend combines BPC-157, KPV, and TB-500 to support gut healing and tissue repair throughout the body.
