Peptides for collagen production don't add collagen — they signal your cells to make more of it. Here's how GHK-Cu, BPC-157, and others stack up for skin, joints, and tendons.
Injectable peptides for anti-aging are changing how people approach longevity — targeting telomeres, growth hormone, collagen, immunity, and mitochondria at the cellular level. Here's what actually works in 2026.
Retatrutide peptide (LY3437943) is the most potent weight loss compound in clinical development — a triple agonist targeting GLP-1, GIP, and glucagon receptors, showing up to 28.7% body weight loss in 68-week trials. Here's everything researchers need to know: mechanism, clinical data, dosing protocols, and sourcing.
Tesamorelin has a better safety profile than most research peptides because it’s FDA-approved and clinically studied, but side effects still happen. The most important ones are injection-site reactions, swelling, joint pain, and blood-sugar changes in susceptible users.
MOTS-c stands out because it is a mitochondria-derived peptide tied to metabolic health, exercise performance, and healthy aging. It’s promising, especially for insulin sensitivity and body-composition support, but it still lives in a limited-data zone.
MOTS-c is commonly used at 5-10mg subcutaneously, 2-3 times per week, with most cycles running 4-8 weeks. This guide breaks down what that actually means in practice, how to scale the dose, and where people usually make mistakes.

5-Amino-1MQ is usually described as fairly well tolerated, with mild GI discomfort and transient headaches being the most common complaints. The bigger issue is not dramatic side effects — it’s the fact that long-term human safety data is still thin.
MOTS-c is generally very well tolerated, with most side effects limited to mild injection-site irritation and occasional fatigue or headache at higher doses. Here’s what those effects usually mean and when they deserve more caution.
Selank is generally well tolerated, but some users notice mild sedation, mental fog at higher doses, or nasal irritation from frequent sprays. Here’s what those effects usually mean and when they deserve more caution.
Selank is usually taken intranasally at 250-500mcg per dose, 1-3 times daily, with most users cycling it for 2-4 weeks before taking a break. This guide covers practical dosing, what to expect, and how to avoid overdoing it.
