Prima 100 - Geneza Pharmaceuticals

Buy GP Prima 100 by Geneza Pharmaceuticals at XSteroids. Each ten millilitre bottle carries methenolone enanthate at 100 mg per ml, the ester that made the trade name Primobolan Depot familiar to a generation of trainers. This page goes through what the single vial holds, how the enanthate tail sets the injection rhythm, what a slow course tends to feel like, how a weekly amount is settled on, which compounds belong next to it, how the axis is taken back afterwards, and which markers decide how long a run may go.

Methenolone is a controlled anabolic steroid in the United States and is banned in sport at all times. The bottle here wears a Geneza Pharmaceuticals label and is supplied as a research product for laboratory and bodybuilding study, so the figures below are reference values drawn from the literature and from what lifters report rather than directions for any reader.

What GP Prima 100 Is and What You Are Buying

Methenolone, also spelled metenolone, is a dihydrotestosterone relative that was built to keep anabolic signalling while dropping much of the androgenic punch. Enanthate is the ester attached at the 17 position, a straight chain that dissolves in oil, stays in the muscle after a shot and is slowly clipped free by enzymes. The 100 mg per ml figure describes ester weight per millilitre, and no outside laboratory has assayed these lots, so the printed number stays a label claim.

The best known reference is Primobolan Depot for the injectable and plain Primobolan for the oral acetate. Both carry the same hormone; the ester and the route are what differ, and this card covers the injectable enanthate in the 100 mg vial.

How Methenolone Enanthate Works After a Shot

Oil deposited in muscle works as a depot. Esterases free the enanthate tail at their own pace, and only the released hormone reaches circulation. Methenolone docks with the androgen receptor in muscle, helps nitrogen stay in tissue and lifts protein turnover, yet its androgenic signal is weak beside testosterone, which is why records describe it as a gentle builder rather than a dramatic one.

The enanthate chain is the longest in this group, with a half life close to ten and a half days, and that single number drives everything. Shots fall once or twice a week, blood levels climb for a few weeks before they level off, and an adjustment made now is judged a fortnight later. Estrogen never enters the picture, because methenolone does not aromatise, so the water and gyno worries that follow testosterone do not appear here.

What to Expect Across a Long Course

Nothing about this compound is loud. Strength edges upward, the physique tightens instead of swelling, and the scale barely shifts because little of the change is fluid. Most of the visible work lands between weeks six and twelve, so a run cut short at four weeks has judged the drug before it could act.

What also has to be expected is a quiet axis. Even a mild androgen pulls luteinising hormone and follicle stimulating hormone down, so natural production drops and fertility can dip while the course is on. The mirror rewards patience with this one and punishes a short run.

GP Prima 100 Dosing and Course Length

Weekly figures reported for the enanthate sit between roughly 200 and 600 mg, split across one or two injections because the ester releases so slowly. A first look at the compound often starts near the bottom of that spread, while experienced users push toward the top or add an oral for the opening fortnight instead of raising the injectable.

The ester cannot be steered quickly, so dose decisions wait for steady blood levels and a blood draw rather than a reaction to a single session. Courses of eight to twelve weeks are normal, and their length is set by how the markers behave, not by a fixed count of weeks.

Three readings carry the plan: total testosterone for the base, a full blood count, and the lipid panel. A haematocrit drifting above the usual band, falling HDL or a haemoglobin that keeps climbing are the cues to shorten the run or lower the weekly total. A red flag in any of them outranks how a training block happens to feel.

Stacking GP Prima 100

Methenolone brings neither estrogen nor testosterone, so a base belongs alongside it. Testosterone Esters and Suspension from Geneza Pharmaceuticals run from propionate to undecanoate and let the base be short or long to suit the plan, while GP Sust 270 does the same job from a single vial.

In a cutting phase a second hard compound usually joins. Drostanolone from Geneza Pharmaceuticals adds density without water, and Oxandrolone from Geneza Pharmaceuticals is the oral pick when appetite and recovery matter. GP Bold 300 fits a slower, fuller look on the same timeline.

Recovery After the Last Prima Injection

The ten day half life sets the tempo here. Hormone keeps arriving for about two weeks after the final shot, and a SERM started before that only races against hormone still on its way in. Wait for clearance, then run a SERM for four to six weeks and keep training steady while natural output comes back.

Geneza keeps two SERMs for that window, GP Nolvadex (tamoxifen) and GP Clomiphene, and one of them is usually enough. Nothing that suppresses the axis has a place in the same stretch.

Methenolone Side Effects and Precautions

With nothing converting to estrogen, the bloat, nipple tenderness and pressure creep seen on testosterone are far less of a feature. What remains is the androgen side: oily skin and breakouts, slower recovery once the dose climbs, and suppression of the body's own testosterone that is certain rather than merely possible.

Methenolone is a Schedule III item in the United States and a class S1 substance on the WADA list, so it is off limits in sport the whole year round. This page describes a research reagent, and none of it is a course of treatment.

Storage Instructions

Stand the bottle upright in a dry cupboard at room temperature, away from sunlight, radiators and steamy rooms. An oil needs no refrigerator, and freezing ruins it. Note the lot number and the expiry date when the vial is first opened, and throw out any bottle that turns cloudy, leaks or carries floating specks.
