This page carries the GP Test E 200 / EQ 200 mix by Geneza Pharmaceuticals, offered here at Best Anabolic Steroids. The pack positions equal parts of boldenone undecylenate and testosterone enanthate in oil, and the two act as one formula rather than as two products poured together.
Below is reference reading drawn from the label and from published pharmacokinetics, including the ranges the two components carry in the sources kept for this project. Read it as background rather than as a prescription, and not as a plan for treating any condition.
Product Overview
Boldenone undecylenate and testosterone enanthate are both injectable androgens sitting on long ester chains, and the combination is built so that the vial delivers a testosterone base and a slower second action from a single draw. The undecylenate arm is the long one, measured around fourteen days at the injection site, while the enanthate arm clears in roughly four and a half days. Read together, the blend releases across a span of about five to fourteen days.
Boldenone is the drier of the two: it aromatises weakly and it drives appetite and red cell production more than it holds fluid. Testosterone enanthate supplies the floor that a cycle needs and brings the estrogenic side of the pair with it. For the profile of the boldenone half on its own, the source sheet behind Boldenone Undecylenate covers it, and the estrogenic behaviour is the same one described across the Testosterone Ester Range.
Because the vial already contains a testosterone base, a cycle built on it does not need a separate testosterone product. What it does need is estradiol management read from blood work, and a recovery plan, because the blend suppresses the axis like any suppressive androgen.
Dosage Protocol
A blend like this has no approved dose. The rows are arithmetic worked out from the two component ranges - boldenone 200-600 mg weekly and testosterone enanthate 250-750 mg weekly at a one-to-one ratio - and are not an instruction.
| Beginner | 400 mg weekly for 12-14 weeks; that is one millilitre, giving 200 mg of each compound |
| Intermediate | 600 mg weekly for 14-16 weeks, which is one and a half millilitres a week |
| Advanced | 800 mg weekly for 14-16 weeks, two millilitres, and only with hematocrit, lipid and estradiol tracking |
| Female | Not recommended; virilization is possible from either half of the blend and no safe protocol exists |
| Administration | Intramuscular oil depot, at least twice a week; the fourteen-day undecylenate arm needs that frequency and the ratio holds at any volume |
The one-to-one ratio does not change if the weekly volume changes: doubling the millilitres doubles both compounds together, which is why the numbers move in whole or half millilitres rather than by adjusting one half.
Suggested Protocols
This blend is a self-contained base, so the second compound is chosen for flavour rather than for a hormonal floor.
Estrogen control is set from a result, and Arimidex is the usual aromatase choice when estradiol reads high. The boldenone half does not convert much, so a low dose assessed on blood work is usually enough.
What to Expect
- Mood and libido move first. The testosterone enanthate arm lifts well-being towards the end of the first week or by week two, before anything visible changes.
- A slow build on the other half. Noticeable gains tied to boldenone usually appear from week six to week eight, which is why these cycles are written long.
- Quality weight by week six to ten. Lean, relatively dry mass arrives in that window, and appetite often rises with it.
- Reds cells climb. Boldenone stimulates erythropoiesis, so hematocrit can drift up on a long cycle and belongs on the blood panel.
- Drier than straight testosterone. The lower aromatisation of the boldenone half means less fluid than an equal dose of a testosterone-only vial, but the enanthate half still holds some.
- Detection is the real limit. Boldenone metabolites have been reported in urine for up to five months, so this is not a blend for anyone subject to testing.
Side Effects and Management
The picture is the enanthate half plus one extra marker: the red cell count that boldenone pushes.
Post-Cycle Therapy
Recovery timing on this blend is the awkward part, because the two esters clear on different schedules and the longer one decides.
Storing the Mix
This is a heavier oil than a single 250 mg/mL ester, so it wants a steady room-temperature shelf, an upright vial and a lid kept tight. Sunlight and damp are the two enemies of an oil depot, and a cold fridge does nothing useful except thicken the solution and invite condensation under the cap.
Because the blend carries two compounds in one barrel, the pint on arrival matters more than usual: confirm the strength, the ratio printed on the label and the batch code against the product page before the first draw. Rotating injection sites keeps a long user comfortable, and a fresh needle for each shot protects the multi-dose container.
If a cleaner, single-hormone base is wanted instead, Test Blend 350 carries testosterone alone in three esters and leaves the fold much sooner.
