Trestolone Enanthate — MENT Long-Ester by Dragon Pharma

Trestolone Enanthate (MENT Enanthate) is Dragon Pharma's long-ester formulation of Trestolone (7α-methyl-19-nortestosterone) at 100mg/ml — the same active compound as MENT 50 (Acetate) with the Enanthate ester replacing the Acetate ester, extending the half-life from ~8 hours to ~7-10 days and reducing injection frequency from daily to twice weekly. For full compound background — anabolic ratio 2,300, androgenic ratio 650, contraceptive history, no testosterone base requirement, and 7α-methyl-estradiol aromatisation — see the MENT 50 page. This page focuses on what the ester change means in practice.

The Ester Difference — What Enanthate Changes vs Acetate

The compound is identical; the ester determines the practical experience of using it:

Parameter Trestolone Enanthate (this product) MENT 50 Acetate
Ester Enanthate Acetate
Half-life ~7–10 days ~8 hours
Injection frequency Twice weekly Daily (or EOD minimum)
Time to peak levels 2–5 days after first injection Hours after each injection
Steady-state Reached in ~3–4 weeks Daily injections stabilise within days
Dose adjustment flexibility Low — effects of a dose change take days High — daily dose changes take effect quickly
PCT timing after last injection 14–21 days 3–5 days
Concentration 100 mg/ml 50 mg/ml

Who Should Choose Enanthate vs Acetate

The ester choice should be driven by practical protocol requirements:

  • Choose Trestolone Enanthate if: you are running a planned, structured cycle of defined length (10-16 weeks) where twice-weekly injection is preferred; you have prior Trestolone experience from MENT 50 and understand your estrogen management requirements; you want the stable blood level profile of a long-ester compound rather than daily injection peaks and troughs; your cycle includes other Enanthate-ester compounds (Testosterone Enanthate, Masteron Enanthate, Primobolan Enanthate) making twice-weekly injection-day coordination straightforward
  • Choose MENT 50 (Acetate) if: this is your first Trestolone cycle and you want daily dosing flexibility to quickly reduce dose or stop if side effects emerge — the Acetate's short half-life means a dose can be skipped and blood levels drop within 24 hours; you prefer the dose control that short-ester daily injection provides; or you are running a short cycle (4-8 weeks) where the Enanthate's 3-4 week ramp to steady-state takes up too large a proportion of the cycle length

Blood Level Curve — The Long-Ester Profile

Understanding the Enanthate blood level profile is essential for managing Trestolone's specific challenges:

  • After the first injection, Trestolone Enanthate levels build gradually — meaningful blood levels are reached by day 3-5, with steady state achieved around weeks 3-4 of twice-weekly dosing
  • This ramp-up phase means side effects also emerge gradually — estrogenic effects (from 7α-methyl-estradiol) and progestin effects build over 2-4 weeks rather than appearing immediately as with Acetate
  • Critically: the slow ramp also means that estrogen management problems (gynecomastia development) can be insidious with Enanthate — it may not be obvious that estrogen is becoming problematic until it is well-established. Starting AI management from injection day 1 is advisable with Enanthate
  • After the last injection, blood levels decline over 2-3 weeks — PCT should not begin until 14-21 days post last injection to avoid starting PCT while active compound is still present

Dosage and Administration

Experience Level Weekly Dose Volume at 100mg/ml Frequency Cycle Length
First Trestolone Enanthate cycle 100–200 mg/week 1–2 ml/week Twice weekly (0.5–1ml per injection) 10–14 weeks
Experienced 200–350 mg/week 2–3.5 ml/week Twice weekly (1–1.75ml per injection) 10–14 weeks

Note that 200mg/week Trestolone Enanthate delivers approximately 200mg of Trestolone with no ester mass deduction — but given the anabolic ratio of 2,300 vs testosterone's 100, this represents an anabolic equivalent well above equivalent testosterone doses. Conservative starting dose is warranted. Estrogen management with Arimidex or Aromasin from day 1 — 7α-methyl-estradiol aromatisation requires AI just as with Acetate, though standard E2 blood tests do not detect 7α-Me-E2 specifically.

Side Effects

  • Same compound, same side effect profile as MENT 50 — estrogenic (7α-Me-E2), progestin activity, complete HPG suppression, androgenic effects despite 5-AR resistance
  • Insidious estrogen buildup — the gradual blood level ramp of the Enanthate ester means estrogenic issues may develop slowly rather than immediately — start AI from injection day 1
  • Complete HPG suppression — Post Cycle Therapy required; begin 14-21 days after last injection
  • HCG during cycle is advisable given Trestolone's complete suppression depth

PCT and Protocol

  • PCT begins 14-21 days after last Enanthate injection — the same timing as any Enanthate ester compound
  • Clomid and Nolvadex for PCT — Trestolone's deep suppression may require a longer than standard 4-week PCT
  • Cabergoline during cycle for prolactin from 19-nor progestin activity — same as with MENT 50

"Trestolone Enanthate delivers the same anabolic ratio of 2,300 as MENT 50 in a twice-weekly injection format — the practical choice for structured longer cycles where daily Acetate injection is impractical and stable long-ester blood levels are preferred."

Storage and Handling

The active compound is identical — both are Trestolone (7α-methyl-19-nortestosterone) with anabolic ratio 2,300. The ester determines the release profile. MENT 50 (Acetate) has an ~8-hour half-life requiring daily injection; blood levels rise and fall quickly, and the dose can be adjusted same-day. Trestolone Enanthate has a ~7-10 day half-life requiring twice-weekly injection; levels build gradually over 3-4 weeks to steady state. The Enanthate provides more stable blood levels but less flexibility for rapid dose adjustment.

Primarily for injection frequency convenience — twice weekly versus daily. For structured 10-16 week cycles where Trestolone is the planned primary compound and side effects are already understood from prior experience, the Enanthate's twice-weekly schedule is practically easier. It also stacks naturally with other Enanthate-ester compounds on the same injection days. The Acetate is preferable for first Trestolone cycles where daily dosing provides rapid response to any side effects, or for shorter cycles where the Enanthate's slow ramp takes too long.

From injection day 1 — do not wait for side effects to appear. Trestolone aromatises to 7α-methyl-estradiol (more estrogenic than regular estradiol) and the Enanthate ester's gradual blood level buildup means estrogenic issues can develop insidiously over 2-4 weeks before becoming obvious. Starting Arimidex or Aromasin from the first injection prevents this slow buildup. Note that standard E2 blood tests measure regular estradiol and do not detect 7α-methyl-estradiol — AI dosing requires symptom-based titration.

14-21 days — the same as any Enanthate-ester compound. The Enanthate half-life of ~7-10 days means meaningful blood levels persist for 2-3 weeks after the last injection. Starting PCT before this period results in attempting HPG stimulation while active suppressive compound is still circulating. HCG during the cycle (not just bridge to PCT) is advisable given Trestolone's complete HPG suppression depth.

No — same as MENT 50 Acetate. Trestolone's androgenic ratio of 650 provides sufficient androgenic environment without exogenous testosterone, as confirmed in NIH male contraceptive trials. Users can run Trestolone Enanthate as the sole injectable compound. However, stacking with Testosterone Enanthate for enhanced mass building is common — the matched esters allow both on the same twice-weekly injection days.

100-200mg/week is appropriate for a first Trestolone Enanthate cycle — 50-100mg per twice-weekly injection at 100mg/ml. Despite Trestolone's exceptional anabolic ratio (2,300), starting conservatively allows assessment of individual estrogen response, which is difficult to predict precisely given that standard E2 tests don't capture 7α-methyl-estradiol. Experienced users extend to 200-350mg/week after establishing their AI requirements.
