Getting Started

Your First Dose: What to Know

You have your prescription, your medication has arrived from a licensed compounding pharmacy, and your provider has outlined your protocol. Now it is time to begin. The first few days and weeks of peptide therapy are important — not because dramatic changes happen immediately, but because this is when you establish the habits, tracking, and communication patterns that determine your long-term success.

Before Your First Dose

Before administering anything, make sure you have completed the following:

• Read all materials from your pharmacy and provider. This includes the patient leaflet, reconstitution instructions (if applicable), dosing schedule, and storage requirements. If anything is unclear, call your provider or pharmacist before proceeding.
• Confirm your dosing schedule. Know exactly how much to administer, how often, at what time of day, and by what route (subcutaneous injection, oral, nasal, etc.). Write it down or set a recurring reminder on your phone.
• Prepare your workspace. If you are doing subcutaneous injections, designate a clean, well-lit area for preparation. Have your supplies organized: vial, syringe, alcohol swabs, sharps container.
• Reconstitute if necessary. Many peptides arrive as lyophilized (freeze-dried) powder and must be reconstituted with bacteriostatic water before use. Follow your pharmacy's reconstitution instructions precisely — the amount of water determines the concentration per unit on your syringe. If you are unsure, refer to our Reconstitution Guide.
• Store properly. Most reconstituted peptides must be refrigerated (36-46 degrees F / 2-8 degrees C). Unreconstituted vials should be stored according to the label — typically refrigerated or at room temperature depending on the compound. Never freeze reconstituted peptides. Review our Storage and Handling Guide for details.

Injection Technique (for Injectable Peptides)

Most peptide therapy involves subcutaneous injections — small injections into the fatty tissue just below the skin. If this is your first time self-injecting, it is completely normal to feel anxious. The needles used are very small (typically 29-31 gauge, half-inch length), and the injection itself is usually painless or causes only a brief pinch.

Key injection basics:

• Wash your hands thoroughly before handling supplies
• Clean the injection site and the vial rubber stopper with an alcohol swab
• Draw the prescribed amount into the syringe, removing air bubbles
• Pinch the skin at the injection site (abdomen, thigh, or upper arm are common)
• Insert the needle at a 45-90 degree angle, inject slowly, withdraw, and apply gentle pressure
• Rotate injection sites to prevent tissue irritation or lipodystrophy

What to Expect in the First Few Weeks

Peptide therapy is not an overnight transformation. Most compounds require consistent use over weeks to months before measurable results appear. Here is a general timeline, though individual responses vary:

Week 1-2:

• You may notice improved sleep quality (especially with GH-releasing peptides taken before bed)
• Some people report a mild increase in energy or mood
• Injection site reactions (mild redness, itching) are common and usually resolve quickly
• Possible temporary water retention or mild flushing after injection

Week 2-4:

• Sleep improvements typically become more consistent
• Recovery from exercise may begin to improve
• Appetite changes may occur (especially with GH-releasing peptides or GLP-1 agonists)
• Skin quality and hair texture improvements may begin (subtle)

Month 2-3:

• Body composition changes may become measurable (reduced body fat, improved lean mass)
• Joint and tissue healing protocols (BPC-157, TB-500) often show noticeable improvement by this point
• Cognitive and mood benefits may become more apparent
• Lab markers should begin to shift — this is when your provider will likely order follow-up labs

When to Contact Your Provider

Contact your provider promptly if you experience any of the following:

• Significant swelling, redness, or pain at injection sites that does not resolve within a day
• Signs of infection: fever, warmth, streaking redness, or pus at injection site
• Persistent headaches, joint pain, or unusual numbness or tingling
• Significant water retention or swelling in hands, feet, or face
• Any symptom that feels wrong or unusual to you — trust your instincts
• You accidentally administered the wrong dose

Tracking Your Progress

Start a simple tracking system from day one. This gives both you and your provider objective data to evaluate your progress and adjust your protocol:

• Daily log: Date, time of injection, dose, injection site, any immediate reactions
• Weekly check-in: Sleep quality (1-10), energy level (1-10), recovery quality, mood, any side effects
• Monthly measurements: Weight, body composition (if you have a scale that measures it), progress photos (optional but useful), subjective assessment of how you feel compared to baseline
• Lab results: Record all lab values over time to track trends
