Argireline
Also known as Acetyl Hexapeptide-3
Argireline, chemically known as acetyl hexapeptide-3, is a synthetic peptide originally developed and studied as a topical cosmetic ingredient marketed for a Botox-like softening of expression lines. It is most extensively researched in topical serum and cream formats, where its large molecular size limits deep skin penetration; this profile instead addresses its use in reconstituted, subcutaneous protocols as discussed in some research and enthusiast contexts. Unlike botulinum toxin, Argireline does not paralyze muscle activity but is proposed to modestly reduce muscle contraction signaling. Evidence for injectable use is considerably more limited than for topical use, and formal clinical trials in this administration route are scarce.
Reported benefits
- Studied topically for reducing the appearance of expression lines
- Proposed to modestly dampen muscle contraction signaling without full paralysis
- Investigated as a non-toxin alternative to botulinum-based treatments
- Explored for use around areas such as the forehead and eye region in topical research
How it works
Argireline is modeled on the N-terminal end of SNAP-25, a protein involved in the SNARE complex that mediates neurotransmitter vesicle fusion at the neuromuscular junction. By mimicking part of this protein, it is proposed to partially interfere with the release of neurotransmitters that trigger muscle contraction, theoretically softening the repeated muscle movements associated with expression lines.

This dose needs 200 units, more than a 100-unit syringe holds. Add more water, split the dose, or use a larger syringe.
A U-100 syringe reads 100 units per mL. This is a reconstitution math helper only, not a prescription or dosing advice. Verify every calculation and consult a qualified healthcare provider.

Stacking notes
Sometimes discussed alongside other cosmetic peptides such as Matrixyl or Snap-8 in combination protocols aimed at broader facial skin support; combined injectable use is not well studied.

Common questions
What is Argireline used for?
Argireline, chemically known as acetyl hexapeptide-3, is a synthetic peptide originally developed and studied as a topical cosmetic ingredient marketed for a Botox-like softening of expression lines. It is most extensively researched in topical serum and cream formats, where its large molecular size limits deep skin penetration; this profile instead addresses its use in reconstituted, subcutaneous protocols as discussed in some research and enthusiast contexts. Unlike botulinum toxin, Argireline does not paralyze muscle activity but is proposed to modestly reduce muscle contraction signaling. Evidence for injectable use is considerably more limited than for topical use, and formal clinical trials in this administration route are scarce. Reported benefits include studied topically for reducing the appearance of expression lines, proposed to modestly dampen muscle contraction signaling without full paralysis, investigated as a non-toxin alternative to botulinum-based treatments.
What is a typical Argireline dose?
Reported ranges run 5-15 mg. A low protocol is 5 mg per session, frequency variable based on protocol, and a high protocol is 15 mg per session, at the higher end referenced in limited protocols. This is reference information, not a dosing recommendation.
What is the half life of Argireline?
Not well characterized for subcutaneous administration; topical formulation studies suggest limited systemic absorption, which does not directly translate to injectable pharmacokinetics.. That is what sets the dosing frequency, and it is why the timing guidance is morning & night (topical).
How is Argireline administered?
Subcutaneous: into fat, under the skin. This profile covers Argireline in reconstituted, injectable/subcutaneous protocols rather than conventional topical cosmetic formulations.
How long is a Argireline cycle?
Protocols described in limited sources suggest periodic dosing over several weeks on, followed by Break periods are not well standardized off. Because injectable use is not the primary studied route for this peptide, cycle information should be treated as exploratory.
What are the side effects of Argireline?
Reported side effects include injection site irritation, given limited data specific to subcutaneous use, uncertain systemic effects due to sparse injectable safety research, possible sensitivity reactions, effects on deeper facial musculature are not well established for this route. Evidence level for this compound is moderate evidence.
