Skin & Hair Peptide Cheat Sheet — Research Notes

Key considerations and protocol notes for each peptide in this cheat sheet.

Healing

ahk

Skin

AHK-Cu

AHK-Cu (Alanine-Histidine-Lysine-Copper) is a copper peptide that promotes collagen synthesis, hair follicle stimulation, and skin remodeling. It is primarily used topically for anti-aging skin care and hair regrowth support, and is not typically administered via injection.

Skin

sna

SNAP-8

SNAP-8 (acetyl octapeptide-3) is a topical peptide that mimics SNAP-25, relaxing facial muscles to reduce expression lines. More potent than Argireline (SNAP-6). Formulated into serums/creams at 4–10 ppm (0.0004–0.001%); used exclusively topically.

Skin

MT-2

Sexual

Melanotan II

Induces tanning and UV protection via MC1-R activation. Load daily until desired tan, then reduce to maintenance dosing (2–3×/week).

Skin

MT-1

Melanotan I

Induces tanning and UV protection with lower side effect profile than MT-II. Load daily until desired tan, then reduce to maintenance dosing.

Frequently asked questions

What is a peptide protocol?

A peptide protocol is a structured research plan that specifies which peptides to study, the quantities and frequencies used in research settings, and the duration of the study period. Research protocols often combine multiple peptides that act on complementary biological pathways—such as tissue repair, cognitive function, or metabolic regulation—to investigate broader or synergistic effects. These protocols are intended for research purposes only and are not a guide for human consumption.

How is peptide dosage calculated from a vial for research?

In a research context, the concentration of a reconstituted peptide solution is calculated by dividing the total peptide content of the vial in micrograms by the volume of bacteriostatic water added in milliliters. For example, a 5mg (5,000 mcg) vial reconstituted with 2mL of BAC water yields a concentration of 2,500 mcg/mL. This information is provided for reference and laboratory calculation purposes only — not as a guide for human use.

How much bacteriostatic water is typically used for peptide reconstitution in research?

Research protocols commonly reconstitute peptide vials with 2mL to 3mL of bacteriostatic water, though the appropriate volume depends on the target concentration needed for a given study. Adding 2mL to a 5mg vial yields a concentration of 2,500 mcg/mL. This information is provided strictly for laboratory and research reference — not as instructions for human use.

How are peptides different from proteins?

Both are composed of amino acids, but peptides are significantly smaller than proteins. Due to their size, peptides can function as precise signaling molecules, binding to specific receptors and triggering targeted biological responses—such as stimulating growth hormone release, promoting tissue repair, or modulating immune activity. These mechanisms are the subject of ongoing scientific research.

Are peptides safe?

Safety profiles vary widely by compound and cannot be generalized. Research considerations include the specific compound, its purity, the quantities studied, the route of administration, and subject health conditions. Some peptides have established clinical trial data; others remain early-stage research chemicals with limited human data. This platform is for research reference only — always review the available peer-reviewed evidence for each compound and consult a qualified medical professional.

Are all peptides medicines?

No. The term "peptide" describes molecular structure—a short chain of amino acids—not regulatory classification. Some peptides are FDA-approved prescription drugs; others are classified as research chemicals and are not approved for human use. Regulatory status varies by compound and jurisdiction. Nothing on this platform should be interpreted as medical or pharmaceutical guidance.

What does peptide reconstitution mean?

Reconstitution is the laboratory process of dissolving a lyophilized (freeze-dried) peptide powder into a sterile carrier liquid—typically bacteriostatic water—to produce a solution of known concentration. The ratio of powder to liquid determines the resulting concentration, which is a key variable in research dosing calculations. This information is provided for research and educational reference only.

How are peptides categorized for research purposes?

Peptides are commonly categorized by their primary biological target or mechanism of action—such as musculoskeletal, neurological, gastrointestinal, or metabolic pathways. Exploring compounds by research area and reviewing the available peer-reviewed literature for each is the recommended starting point for any research protocol design. This platform does not provide personalized recommendations.
