Product overview

Geneza Pharmaceuticals GP Test Blend 350

GP Test Blend 350 is a Geneza Pharmaceuticals testosterone product that puts three esters into one oil at 350 mg per ml: testosterone propionate, cypionate and enanthate, with the two long esters holding most of the label. The concentration is higher than the classic 250 mg per ml blends. It is the same idea as Testo Blend 350 and Sustaplex: fast esters give an early rise, slow esters hold the level, and a smaller injection volume carries the same total dose as a lower-strength blend.

How Test Blend 350 Works

Esterases in blood and tissue strip the ester from the molecule at different speeds, so the blend releases in stages: the short fraction acts within a day or two and the long fraction keeps releasing for weeks. Free testosterone then binds the androgen receptor, and part of the dose is converted by aromatase into estradiol and by 5-alpha reductase into dihydrotestosterone, which is why water retention and scalp hair effects belong to the class. The pituitary reads the rising level and reduces LH and FSH, shutting down natural production.

Dosage & Administration

No medical dose is stated, because this vial is a research product and not a licensed medicine. What matters with a 350 mg per ml blend is arithmetic: a smaller volume holds the same milligrams, so the week total should be worked out from the concentration instead of copied from a 250 mg per ml product. The slow esters also delay the fall after the last shot, which stretches the recovery window. Estrogen control with Arimidex is added only when needed, and recovery is Nolvadex 20 mg daily for four weeks with Clomid as the alternative. Keep the vial at room temperature, away from light, heat and moisture.

Stacks

Blend 350 as the Mass Base

GP Test Blend 350 as the only androgen, injecting on a fixed weekly schedule so the fast esters in the blend are covered before they fade.

PCT: required - the blend suppresses natural testosterone.

High-Concentration Base With a Milder Oral

Because 350 mg per ml needs a smaller volume, the blend is often used when injection volume is the limiting factor, with a mild oral filling the rest of the run.

PCT: required - Nolvadex 20 mg daily for 4 weeks, Clomid as the alternative.

Consult a healthcare professional before any cycle. Doses are common community protocols.

FAQ

Before you ask

Questions, answered

GP Test Blend 350 is a Geneza Pharmaceuticals testosterone product holding three esters in one oil at 350 mg per ml. It is used in laboratory work as a concentrated mixed-ester testosterone sample, and in sports as an androgen base that starts quickly and lasts, because the short esters act within days and the long esters keep the level up. It is not a licensed medicine.

No published medical schedule exists for this vial. The concentration is the key number: at 350 mg per ml one millilitre carries far more testosterone than a millilitre of a 250 mg per ml blend, so weekly milligrams should be calculated rather than guessed from another product. The short esters in the mix set how often injections have to be repeated.

The class warnings are acne, oily skin, scalp hair loss, mood changes, irritability, aggression, sexual dysfunction and shrinkage of the testicles, plus more serious risks of raised blood pressure, heart problems, stroke, liver damage and blood clots. Testosterone aromatises to estradiol, so water retention and breast tenderness can appear. High-concentration oils can also cause more injection-site discomfort than dilute ones.

Mainly in concentration, and therefore in volume. The same weekly milligrams need about two thirds of the liquid at 350 mg per ml compared with 250 mg per ml, which suits users who want smaller or fewer shots. The esters still govern the release curve, so the blend is not faster or slower as a class, only more concentrated.

Yes. The blend suppresses the body's own testosterone output, so recovery is planned after the last injection. The usual protocol is Nolvadex 20 mg daily for four weeks, with Clomid as the alternative. Because the long esters in the blend keep releasing for weeks, the level falls slowly rather than the day after the last shot.

Yes, the vial is listed on this page with international and U.S. domestic shipping options.
