Order GP Sust 270 from Geneza Pharmaceuticals here at Best Anabolic Steroids. The page covers one oil vial: 270 mg of testosterone per millilitre carried on five different esters, 10 ml to the container. Nothing accompanies the hormone in the oil - the five chains are simply testosterone attached to molecules of different lengths.
What follows is laboratory reference reading assembled from the label values and from published pharmacokinetics. It explains how the blend behaves in the body and how the numbers behind it are usually read. Treat it as reference material rather than a prescription, and note that nothing in it is a care plan for any condition.
Product Overview
One millilitre divides as follows: acetate contributes 20 mg, propionate 30 mg, phenylpropionate and isocaproate 60 mg each, and decanoate takes the largest share at 100 mg. The two short chains open the curve within a day or two of a shot, the middle pair carries the level through the week, and the decanoate arm supplies the long tail that lets a twice-weekly schedule hold steady between pins.
The hormone is identical to every other testosterone ester. What changes with the ester is onset, how often the vial has to be opened and how long the washout runs before recovery drugs make sense. For a single-ester comparison against this formula, Testosterone Ester Range sets enanthate, cypionate, propionate and undecanoate side by side.
Because the vial is pure testosterone, the whole dose aromatises and it suppresses the axis like any other suppressive androgen. Users who want a slower, heavier companion for a mass phase often read about Nandrolone Deca and NPP Range next to it. The reason to pick a blend is fewer injections, not a different outcome.
Dosage Protocol
This product holds no approved dose. The bands below come from vendor references together with the general testosterone ranges kept in this folder.
| Beginner | 270 mg weekly for 10 weeks; at this strength that is 1 mL a week split across two shots |
| Intermediate | 400-600 mg weekly for 10-12 weeks, divided into two injections |
| Advanced | 600-750 mg weekly for 12-16 weeks, still on a twice-weekly rhythm |
| Female | No documented protocol in the sources; virilization remains possible at any dose |
| Administration | Intramuscular oil depot on a two-shot week, spaced three to four days apart, with the sites rotated |
A second vendor profile quotes much wider bands - 250-500 mg weekly for a first attempt, up to 750-1000 mg or more for experienced users. Both sets are recorded here rather than averaged, and the upper figures belong only to people who track blood work.
Suggested Protocols
Three arrangements cover most of what people do with a five-ester testosterone.
Estradiol is steered by a blood result rather than by feel: Arimidex is the usual aromatase option quoted with a testosterone base. Where a wetter oral kickstart is preferred, Oxymetholone is the other four-week choice, and it is never run past that point because of its liver load.
What to Expect
- Activity inside two days. The acetate and propionate arms release within 24 to 48 hours, so something is happening well before the long chains do any work.
- A clinical peak to compare against. In the four-ester clinical reference, plasma testosterone tops out near 70 nmol/L about one to two days after a single 250 mg injection before sloping away.
- The usual testosterone timeline from week three. Strength, fullness and libido shift in weeks three to six, and fluid and blood pressure track estradiol instead of the ester list.
- Water and pressure arrive early if estradiol is ignored. Five esters do not soften the aromatisation of the whole dose.
- The tail is slow. In the clinical reference the level returns to the bottom of the normal male range about three weeks after the last shot, which sets the recovery calendar.
- Result still follows food and training. The blend changes the release curve only; calories, protein and sleep decide what the curve produces.
Side Effects and Management
Every item here comes from one place: the whole dose aromatises, and a suppressive androgen switches the axis off.
Post-Cycle Therapy
The decanoate arm governs the wait, so recovery starts on a known date rather than on a feeling that the shot has worn off.
Handling and Storage
An oil depot lives best in a dry cupboard at room temperature, lid tight and out of direct light. Cold is not the friend of an oil solution: refrigeration can thicken it and, worse, let condensation in around the stopper. Before a shot, warming the vial in the hand thins the oil and eases the push through a fine needle.
Check the printed strength and the batch on the label when the parcel arrives, and keep the vial upright. Sites should be rotated rather than reused, and a fresh needle for every draw keeps the multi-dose container clean for its ten millilitres.
For a shorter-ester alternative with the same hormone, Test Blend 350 concentrates the work in propionate, cypionate and enanthate, and clears sooner before recovery begins.
