Educational reference, not a pharmacy: compounded peptide protocols, dose ranges, cycle length and reconstitution math for 40+ peptides. Free, no sign-up.
The Peptide Guide 2026 is our full protocol reference: reconstitution math, dose ranges, frequency, cycle length, stacking, side effects, bloodwork, and storage for every peptide category we cover.
Each category below is also published as its own focused page so you can jump straight to the intent you came for.

A peptide is a short chain of amino acids (typically 2–50) that acts as a biological signaling molecule. Therapeutic peptides leverage the body's natural pathways to influence growth, metabolism, recovery, immunity, mood, and reproduction with targeted effects and shorter half-lives than most traditional pharmaceuticals.
Clean both rubber stoppers with alcohol, draw the calculated amount of bacteriostatic water into an insulin syringe, insert the needle at an angle into the peptide vial, and release the water slowly down the glass wall — never directly onto the powder. Swirl gently until fully dissolved (do not shake). Label the vial with peptide, concentration, and date, and refrigerate at 2–8 °C.
Semaglutide is a GLP-1 receptor agonist. Tirzepatide is a dual GIP/GLP-1 agonist with greater average weight loss in trials. Retatrutide is an investigational triple GLP-1/GIP/glucagon agonist showing the largest Phase 2 weight reductions to date. All three are weekly subcutaneous injections; titrate slowly to minimize GI side effects.
The Wolverine Stack pairs BPC-157 and TB-500 for comprehensive injury recovery. BPC-157 supports tendon, ligament, and gut repair; TB-500 promotes cell migration and broader tissue healing. Typical research protocol: 250–500 mcg BPC-157 daily plus 2–5 mg TB-500 twice weekly for 4–6 weeks.
The Gold Standard stack combines CJC-1295 (a GHRH analog) with Ipamorelin (a selective ghrelin-receptor agonist). Used together at bedtime, they produce a clean, pulsatile growth-hormone release without spiking cortisol or prolactin. Typical research dosing: 100 mcg of each, 5 nights on / 2 off.
In the United States, FDA-approved peptides such as Semaglutide (Ozempic/Wegovy), Tirzepatide (Mounjaro/Zepbound), Teriparatide (Forteo), and PT-141 (Vyleesi) require a prescription. Most other peptides are classified as research compounds and are not FDA-approved for human use. Always consult a licensed healthcare professional.
Lyophilized (powdered) peptides keep 18–24 months refrigerated at 2–8 °C or up to 5 years frozen at −20 °C. Once reconstituted with bacteriostatic water, refrigerate at 2–8 °C and use within 28–30 days. Protect from light, never shake, and discard if cloudy or discolored.
Baseline labs should include a CBC, CMP, lipid panel, hormone panel (testosterone, estrogen, IGF-1, GH), fasting insulin, HbA1c, liver enzymes, and inflammatory markers (hs-CRP). Retest every 4–8 weeks during active protocols and track sleep, energy, mood, appetite, and injection-site reactions daily.
Avoid stacking multiple GLP-1 agonists (Semaglutide + Tirzepatide), combining GHRH analogs without a ghrelin mimetic (which blunts response), and using Melanotan II alongside other melanocortin agonists like PT-141 due to additive cardiovascular and pigmentation effects.
