Protocol
Testagen (20mg Vial)
Complete dosage protocol and reconstitution guide for Testagen (20mg Vial).
Calculator preset
Run the vial math before tracking.
At ~6.67 mg/mL, 1 unit ~ 66.7 mcg ; 100 mcg ~ 1.5 units and 200 mcg ~ 3 units . Doses are small - a 30/50-unit syringe reads best.
01 · At a glance
Quickstart Highlights
Testagen is a synthetic tetrapeptide with the sequence Lys‑Glu‑Asp‑Gly (KEDG), an anterior pituitary‑derived bioregulator studied for its role in modulating endocrine function, particularly the pituitary–gonadal axis [1] [2] . Preclinical research indicates effects on thyroid hormone normalization and male reproductive hormone modulation [3] [4] . This educational protocol presents a once‑daily subcutaneous approach using a practical dilution for clear insulin‑syringe measurements.

Dosing & Reconstitution Guide
A practical calculator-ready setup based on the imported protocol reference. Use these values as a math starting point, then verify every entry against your own vial, diluent, and professional guidance.
Standard / Gradual Approach (3 mL = ~6.67 mg/mL)
100–300 mcg once daily (gradual titration).
Reconstitution Steps
- Draw 3.0 mL bacteriostatic water with a sterile syringe.
- Inject slowly down the vial wall; avoid foaming.
- Gently swirl/roll until dissolved (do not shake) [5] .
- Label and refrigerate at 2–8 °C (35.6–46.4 °F) , protected from light.

Supplies Needed
Keep this as a planning checklist. TNHL does not sell or verify supplies on this page, and no supplier quality claims are made here.
- 12 weeks (~25 mg used) ≈ 2 vials
- 16 weeks (~36 mg used) ≈ 2 vials
- 8 weeks: 56 syringes
- 12 weeks: 84 syringes
- 16 weeks: 112 syringes
- 8 weeks (1 vial): 3 mL → 1 × 10 mL bottle
- 12 weeks (2 vials): 6 mL → 1 × 10 mL bottle
- 16 weeks (2 vials): 6 mL → 1 × 10 mL bottle
- Per week: 14 swabs (2/day)
- 8 weeks: 112 swabs → recommend 2 × 100‑count boxes
- 12 weeks: 168 swabs → recommend 2 × 100‑count boxes
- 16 weeks: 224 swabs → recommend 3 × 100‑count boxes
Protocol Overview
- Goal: Support endocrine function research, particularly pituitary–gonadal axis modulation [1] [2] .
- Schedule: Daily subcutaneous injections for 8–12 weeks (extend to 16 weeks if desired).
- Dose Range: 100–300 mcg daily with gradual titration.
- Reconstitution: 3.0 mL per 20 mg vial (~6.67 mg/mL) for accurate unit measurements.
- Storage: Lyophilized frozen; reconstituted refrigerated; avoid repeated freeze–thaw.
Dosing Protocol
- Suggested daily titration approach.
- Start: 100 mcg daily; increase by ~50 mcg every 2 weeks as tolerated.
- Target: 200–300 mcg daily by Weeks 5–12.
- Frequency: Once per day (subcutaneous).
- Cycle Length: 8–12 weeks; optional extension to 16 weeks.
- Timing: Any consistent time; rotate injection sites.
Storage Instructions
- Lyophilized: freeze at −20 °C (−4 °F) ; after reconstitution, refrigerate at 2–8 °C (35.6–46.4 °F) ; avoid freeze–thaw cycles.
- Storage: Lyophilized frozen; reconstituted refrigerated; avoid repeated freeze–thaw.
- Keep mixed and unmixed items clearly labeled so inventory and dose logs stay accurate.
04 · Good to know
Important Notes
- Practical considerations for consistency and safety.
- Use new sterile insulin syringes; dispose in a sharps container [7] .
- Rotate injection sites (abdomen, thighs, upper arms) to reduce local irritation [8] .
- Inject slowly; wait a few seconds before withdrawing the needle.
- Document daily dose and site rotation to maintain consistency.
- Due to very low injection volumes (≤5 units), a 30‑ or 50‑unit syringe is recommended for precision.

The library page pairs that educational context with calculator-ready vial math, so users can understand the protocol structure and then track their own entered values in one place.
06 · Daily habits
Lifestyle Factors
- Keep meals, training, sleep, and recovery notes in the journal so trends are easier to review.
- Track body metrics only if they are relevant to the user's goal and approved data sources.
- Use consistent timing and logging habits so adherence data is meaningful.
07 · What to expect
Potential Benefits & Side Effects
- Testagen observations should be recorded conservatively: expected research endpoints, tolerability notes, injection-site reactions when applicable, sleep, appetite, energy, mood, and any adverse or unusual response.
- This section is not a claim of therapeutic benefit.
08 · Technique
Injection Technique
- Wash hands with soap and water.
- Wipe the vial stopper and chosen site with alcohol, then let both dry.
- Confirm the vial concentration, calculator result, and intended draw amount before loading the syringe.
- Use the route and needle technique directed by a qualified professional or product instructions.
- For subcutaneous injections, rotate sites and inject slowly to limit leakage and irritation.
- Do not reuse needles or syringes.
- Dispose of sharps in a puncture-resistant container.
- Return stored items promptly to the correct temperature.
- Log dose, site, date, time, inventory change, and any observation.
