Mass Cycle - Testosterone and Deca

What is in this Mass Cycle pack

A classic mass run built from Dragon Pharma products: a higher testosterone dose for the base and nandrolone decanoate to drive size.

• Testosterone Enanthate 250 - two 10 ml vials at 250 mg/ml.
• Deca 300 - one 10 ml vial at 300 mg/ml.

How to run it

Testosterone enanthate

Dose: 500 mg per week for 10 weeks, split into two injections of 1 ml, for example Monday and Thursday. Two vials cover the full ten weeks.

Deca

Dose: 300 mg per week for 10 weeks, 1 ml once a week. Decanoate is a long ester: one weekly injection is enough, and it keeps building for weeks after the last shot.

Injection basics

Two compounds, at least three pins a week if you split the testosterone. Rotate sites and keep a written schedule: this cycle is long enough that consistency decides the result.

Support on cycle

At 500 mg of testosterone per week, an aromatase inhibitor is more likely to be needed than on a first cycle. Symptoms to watch: nipple tenderness, sudden water retention, mood swings. Deca adds its own considerations: 19-nor compounds can raise prolactin and often reduce libido during the run. Both AI options are in on cycle support, Cabergoline is in post cycle therapy.

Bloodwork

Baseline, week 5, and after the cycle. Add prolactin. Deca affects cholesterol values, so include a full lipid panel.

What to expect

Steady size, improved joint comfort, and more water retention than testosterone alone. Gains come slower than with orals but hold better. This is a long cycle by design: ten weeks of injections, then three weeks of waiting, then recovery.

Buying the items separately

Both products are also listed on their own in our injectable steroids section, and nandrolone decanoate has its own category page covering every ester.

How this compares to a testosterone-only cycle

A testosterone-only cycle at 500 mg per week is lighter on recovery and easier to read from bloodwork. Adding decanoate brings more size and better joints at the cost of a slower recovery and a three week wait before PCT. If this is your first heavier cycle, run testosterone alone once and add Deca next time.

General information for adults researching performance compounds, not medical advice. Doses and durations differ from person to person; decisions about your health belong with a qualified professional.

When recovery starts

Wait about 21 days after the last injection of this cycle. Decanoate clears slowly, and starting PCT early wastes it while the compound is still active.

Standard protocol

• Weeks 1 and 2: Clomid 50 mg per day.
• Weeks 3 and 4: Clomid 25 mg per day, or Nolvadex 20 mg per day if Clomid is hard to tolerate.

Both, plus HCG, are in our post cycle therapy section.

While you wait

The three weeks between the last injection and PCT are not a rest period: keep training and eating, and expect libido and mood to dip as levels fall. HCG can be used at the end of the cycle for testicular function, not during PCT.

Ancillaries

Arimidex or Aromasin for estrogen symptoms, Cabergoline if prolactin rises: on cycle support.

Bloodwork after PCT

Total testosterone, LH, FSH, estradiol and prolactin four weeks after PCT ends, plus a lipid panel. Deca cycles recover more slowly than testosterone-only cycles, so do not rush the next one.
