Total Doses:

20

injections in vial

For Each 250 µg Dose:

Volume Needed:

0.100 mL

On Insulin Syringe:

10.0 units

Formulas Used:

Concentration (µg/mL) = Total Peptide (µg) ÷ Water Volume (mL)Volume Needed (mL) = Desired Dose (µg) ÷ Concentration (µg/mL)Syringe Units = Volume (mL) × 100

Note: Standard insulin syringes measure 0.01mL per unit (100 units = 1mL)

Peptide Guide & Best Practices

Common Therapeutic Peptides

BPC-157

Tissue repair, gut health, injury healing. 250-500 µg, 2x daily

TB-500

Muscle repair, inflammation, flexibility. 2.5-5mg, 2x weekly

Ipamorelin + CJC-1295

GH release, anti-aging, recovery. Combined for synergy

GHK-Cu

Skin health, collagen, wound healing. 1-3mg daily

Storage & Handling

  • Lyophilized (powder): Store at -20°C (freezer) for long-term, 2-8°C (fridge) short-term
  • Reconstituted: Refrigerate at 2-8°C, use within 14-30 days
  • Bacteriostatic water: Contains 0.9% benzyl alcohol as preservative
  • Light sensitive: Many peptides degrade in light, use amber vials
  • Avoid freezing reconstituted peptides - damages protein structure

Injection Technique

  • • Subcutaneous (SubQ) injection most common - abdomen, thigh, arm
  • • Use insulin syringes (29-31 gauge) for accuracy and comfort
  • • Rotate injection sites to prevent lipohypertrophy
  • • Clean injection site with alcohol swab
  • • Inject slowly, withdraw slowly, dispose properly

Reconstitution Steps

  1. Remove flip cap from peptide vial, wipe rubber stopper with alcohol
  2. Draw calculated amount of bacteriostatic water into syringe
  3. Inject water slowly down the side of vial (NOT directly onto powder)
  4. Gently swirl (DO NOT SHAKE) until fully dissolved
  5. Label vial with peptide name, concentration, and date

Important Safety Information:

  • • Peptides are research chemicals - not FDA approved for human use
  • • Source from reputable suppliers with third-party testing (purity, sterility)
  • • Consult healthcare provider before use, especially with medical conditions
  • • Watch for allergic reactions, injection site reactions, side effects
  • • Do not share needles or vials - risk of infection
  • • Improper storage or reconstitution can render peptides inactive or harmful
