Product Overview
Primobol Inject is the British Dragon version of methenolone enanthate, sold as a 100 mg per ml oil for deep intramuscular use. Methenolone comes from the dihydrotestosterone branch, but its anabolic-to-androgenic ratio sits on the mild side, which is the whole reason it has a following: it produces steady, modest gains with no estradiol conversion and no fluid retention. The enanthate ester is the longest in the methenolone family, with an elimination half-life of roughly ten days, so a single injection holds level for a long time and the cycle runs for months rather than weeks.
That profile sets the expectations honestly. Methenolone is not a fast drug, and users who run it too low or for too short report very little, because the compound adds quality rather than scale weight. What it does give, when the dose and duration are adequate, is dry muscle gain with a low side-effect load and a look that holds during a calorie deficit. It is frequently described as a beginner-friendly injectable for that reason, provided the user accepts the long time frame and the cost of running enough of it.
The practical partner is a testosterone ester that supplies the androgen base, since methenolone suppresses natural production without replacing it. On this catalogue that base is usually Testabol Depot, and estrogen control follows that base with Anastrozole rather than with anything aimed at the Primobol. A dry oral such as Oxanabol 10 is often added for the final weeks of a cutting phase.
Dosage Protocol
Weekly figures below are taken from the reference sheet for methenolone enanthate in this folder. No approved human dose exists for the product itself.
| Entry level | 200-300 mg a week, split into two shots, over 10-12 weeks; the mild profile means the wait for a visible result is long |
| Established users | 400-500 mg a week for 12 weeks, usually beside a testosterone base rather than on its own |
| Upper end | 600 mg a week for 12-16 weeks; nothing above this figure is supported by the sources consulted |
| Female | Only low doses with close supervision are described anywhere, and no verified female protocol exists; the virilization risk is lower than with most compounds but not absent |
| Administration | Deep intramuscular injection twice weekly; the long ester makes a 10 ml vial last a short time at high weekly totals, so plan supply against dose |
Suggested Protocols
Three arrangements reflect how methenolone is actually run. Each one keeps a testosterone ester in place, because the compound alone does not cover the androgen side.
What to Expect
- Slow build. The compound accumulates rather than spikes, and the first changes are usually reported around week three to five.
- Weeks 6-8. A clean, dry increase in muscle quality without the puffiness that comes with aromatizing compounds.
- No fluid, no gyno. Methenolone does not convert to estradiol, so neither water retention nor gynecomastia is part of its own profile.
- Strength. Gains are steady rather than dramatic and hold up during a calorie deficit, which is why it is popular in a diet.
- Mild side-effect load. Most users describe fewer complaints than on stronger injectables, provided the testosterone base is managed sensibly.
- Cost of mildness. Underdosing produces almost nothing; the drug rewards a full dose and a long run, and punishes neither patience nor money.
- Limit. It is a finishing and quality compound, not a mass builder, and it does not replace calories or training.
Side Effects and Management
Methenolone is among the better-tolerated injectables, which does not mean it is side-effect free; the list is short but real.
Post-Cycle Therapy
The roughly ten-day half-life sets a longer clearance than most injectables, so recovery starts later than a short-ester cycle would.
