Essential Safety Guides ​

Blood Testing and Monitoring ​

Regular blood testing is the cornerstone of safe hormone therapy practice. Key tests to monitor include:

For Transfeminine Individuals:

  • Estradiol (E2) - Target: 100-200 pg/mL (trough)
  • Total Testosterone (T) - Target: < 50 ng/dL
  • Liver Function Tests (ALT/AST) - Especially important with spironolactone or bicalutamide
  • Potassium - Critical when taking spironolactone
  • Prolactin - Monitor for elevated levels
  • Hemoglobin/Hematocrit - Watch for polycythemia risk
  • Lipid Panel - Cholesterol and triglycerides
  • SHBG - Sex Hormone Binding Globulin levels

For Transmasculine Individuals:

  • Total Testosterone (T) - Target: 300-1000 ng/dL (trough)
  • Estradiol (E2) - Target: < 50 pg/mL
  • Hematocrit/Hemoglobin - Monitor for polycythemia (Hct > 54% concerning)
  • Liver Function Tests (ALT/AST)
  • Lipid Panel
  • Red Blood Cell Count
  • Vitamin D levels

Injection Safety ​

Proper injection technique reduces risks of infection, pain, and complications:

Supplies Needed:

  • Appropriate syringe size (1mL for most hormones, 3mL for testosterone undecanoate)
  • Correct needle gauge and length (see injection guides)
  • Alcohol swabs for skin preparation
  • Sharps container for safe disposal
  • Bandages or adhesive strips

Injection Sites:

  • Intramuscular (IM): Thigh (vastus lateralis), hip (ventrogluteal), shoulder (deltoid)
  • Subcutaneous (SubQ): Abdomen (away from navel), thigh, upper arm
  • Site rotation: Essential to prevent lipohypertrophy and scarring

Technique Tips:

  • Always use aseptic technique
  • Never reuse needles or syringes
  • Proper disposal in puncture-proof sharps container
  • Apply pressure after injection to minimize bruising
  • Monitor for signs of infection (redness, swelling, warmth, pus)

Medication Sourcing and Verification ​

Reducing risks associated with medication quality and authenticity:

Supplier Evaluation:

  • Look for community-vetted sources with transparent testing
  • Check for batch numbers and expiration dates
  • Verify packaging matches legitimate pharmaceutical products
  • Start with small test orders when trying new suppliers

Red Flags to Watch For:

  • Prices that seem too good to be true
  • Vendors who refuse to provide product photos or batch information
  • Pressure to use untraceable payment methods only
  • Numerous reports of under-dosed or contaminated products
  • Lack of community reputation or history

Verification Methods:

  • Compare pills to known legitimate samples (size, color, markings)
  • Use reagent test kits when available (for certain compounds)
  • Community testing initiatives for hormone concentration
  • Visual inspection of packaging quality and seals

Harm Reduction Practices ​

Core principles for safer DIY-HRT:

Start Low, Go Slow

  • Begin with lower doses than standard regimens
  • Increase gradually based on blood tests and tolerance
  • Allow time for your body to adjust between changes

One Change at a Time

  • Modify only one medication or dosage at a time
  • Wait 4-8 weeks between changes to assess effects
  • This helps identify which change caused any observed effects

Regular Monitoring

  • Schedule blood tests every 3 months initially
  • Track symptoms alongside lab results
  • Adjust based on both objective data and subjective experience

Community Engagement

  • Participate in harm reduction forums and groups
  • Share experiences (both positive and negative) to help others
  • Learn from the experiences of more experienced community members
  • Contribute to collective knowledge through reviews and feedback

Emergency Preparedness ​

Knowing when to seek immediate medical attention:

Seek Emergency Care For:

  • Signs of allergic reaction (difficulty breathing, swelling of face/lips/throat, hives)
  • Signs of blood clot (sudden leg swelling, pain, redness; chest pain; shortness of breath)
  • Signs of infection at injection site (increasing redness, warmth, swelling, pus)
  • Severe abdominal pain (especially with spironolactone use)
  • Yellowing of skin or eyes (jaundice - possible liver issue)
  • Severe depression or suicidal thoughts
  • Chest pain or palpitations
  • Severe headache with vision changes or neurological symptoms

When to Contact a Healthcare Provider (Non-Emergency):

  • Persistent side effects that impact quality of life
  • Concerns about dosage effectiveness
  • Questions about medication interactions
  • Need for documentation or referrals
  • Routine check-ups and preventive care

Community Resources ​

Testing Collectives ​

Many communities organize group blood testing to reduce costs:

  • Pool resources to purchase multiple tests at discounted rates
  • Share transportation costs to testing facilities
  • Provide mutual support during the testing process
  • Often organized through Discord servers or local meetups

Educational Materials ​

  • Video tutorials for safe injection techniques
  • Guides on proper medication storage and handling
  • Calculators for accurate dosing based on concentration
  • Interactive tools for tracking symptoms and lab results

Peer Support Networks ​

  • Online communities for sharing experiences and advice
  • Local meetups for in-person support and resource sharing
  • Mentorship programs connecting experienced and newer practitioners
  • Crisis support lines and mental health resources
