Research chemical vendors can't legally label products with the real name, so Testagen often appears under coded SKUs. If you're shopping and see any of these, it's the same compound:

Your draw
What it actually is
Testagen is a short synthetic peptide from the Khavinson bioregulator family. This class is proposed to bind regulatory regions of DNA in specific tissues and normalize gene expression, meaning effects show up in bloodwork and tissue function rather than as an acute feel.
2mg daily for 30 consecutive days, then a 2 month break, 2 to 3 courses per year. Nothing is felt acutely: this class works slowly by design.
Why people use it
- Reproductive and testicular function support with age
- Interest in Khavinson's Russian longevity research
- Non-hormonal approach, no HPTA suppression

Typical timeline
General pattern for the Bioregulator category. Individual response varies.
- Days 1–10No acute effects. This class works at the gene expression level — subtle by design.
- Days 10–20Organ-specific improvements accumulate. Bloodwork often reflects the change more than symptoms do.
- Post-cycleBenefits persist 2–4 months. Standard cadence is 20–30 days on, then a 2-month break, 2–3 cycles per year.
The reconstitution math
- 1Reconstitute the 20 mg vial with 2 mL of bacteriostatic water. Tilt — don't shake.
- 2Concentration becomes 10,000 mcg/mL (10 mg/mL).
- 3For a 2 mg dose, draw 0.200 mL — that's 20 units on a 1 mL insulin syringe.
- 4One vial gives you approximately 10 doses.
Reminder: 100 units on an insulin syringe = 1 mL. Always start at half the listed dose for the first week and rotate injection sites between arms, legs, abdomen, and glutes.
