Product Overview
Primoplex 100 is the Axiolabs methenolone enanthate, supplied as a 10 ml multi-dose vial at 100 mg/ml. Methenolone is a DHT-derived injectable androgen with a moderate anabolic and a weak androgenic profile, and the enanthate ester is its longest form: half-life around ten and a half days, two injections a week, and weeks of clearance after the last shot.
Its reputation rests on being gentle rather than strong. Nothing here is converted to estradiol, so fluid does not build up and gynecomastia does not form part of its profile, and no hepatic risk is described for the compound. What it will not do is deliver size quickly: the effect builds over weeks, clean and dry, which is why cycles run for ten to sixteen weeks.
The honest cost is efficiency. Methenolone gives less result per milligram than most injectables, so a proper cycle uses a lot of hormone and a lot of vials, and it still suppresses natural production while it runs.
Dosage Protocol
Bands below restate reference material for methenolone enanthate; they are a starting point for comparison rather than an approved schedule.
| Beginner | A first run sits at 200-300 mg weekly across 10-12 weeks; that measures 1-1.5 ml from this vial across two shots |
| Intermediate | 400-500 mg each week for 12 weeks, usually beside a testosterone base |
| Advanced | 600 mg each week for 12-16 weeks, with nothing above that confirmed in the sources checked |
| Female | Low doses under supervision only; methenolone is gentler than most, but virilization remains a real risk |
| Administration | Intramuscular, twice a week; the long ester is what makes a long cycle practical in the first place |
A cycle of this length asks for monitoring rather than hope. Lipids and hematocrit drift over ten to sixteen weeks even when the compound is mild, and the last injection sets the start of recovery, which is later than after any short-ester product on the same shelf.
Suggested Protocols
Methenolone is almost always paired with a testosterone ester, because it does not supply enough androgen on its own to cover a full cycle.
A mass build instead of a recomp is served better by Equiplex Forte 300 or Sustaplex 350, both of which deliver more per milligram. Methenolone is bought for its manners, not its power.
What to Expect
- A slow start. The first changes are usually noticed between week three and week five, which is why a four week experiment with this compound tells you nothing.
- Clean gains by week six to eight. Quality muscle arrives without a bloated look, and bodyweight moves gradually rather than in jumps.
- Nothing watery. No water retention and no breast tenderness, because the compound does not aromatize.
- Fewer complaints than most. Milder in practice than the stronger injectables, which is not the same as harmless.
- Lipids and the axis still move. HDL falls and natural production is suppressed even at moderate doses, so blood work stays part of the job.
- It is expensive per milligram. Getting a result takes volume, and volume takes vials; that is a planning fact, not a flaw.
Side Effects and Management
Post-Cycle Therapy
Methenolone is mild on the way in and slow on the way out. The enanthate ester is the reason recovery starts late.
Because cycles here are long, hematocrit and blood pressure belong in the mid-cycle blood work as well, not only in the recovery panel. A gentle compound taken for sixteen weeks is still sixteen weeks of exposure.
Storage and Handling
The vial is an oil: room temperature, dark, upright, capped, and never frozen. Swab the stopper with alcohol before every draw, fit a fresh needle each time, and rotate injection sites to keep the oil from irritating the same spot twice a week. At 100 mg/ml the millilitres per dose are large, so a 500 mg week means 5 ml of oil across two injections; that volume is worth splitting sensibly rather than concentrating into one site. Retire a vial that has gone cloudy or gritty.
Buying Primoplex Online
Primoplex 100 sits in the Axiolabs injectable line, and the concentration, vial size and price are shown before checkout, so the volume a full cycle requires can be worked out honestly at the planning stage. Other mild or dry options of the line, such as Mastaplex 100 and Ultraplex 150, are listed on the same shelf. Parcels leave in plain packaging, domestic and international shipping are both offered, and questions about dosing, cycle length or pairing the vial with a base can be answered before the order is placed.
