Hemi Pharma TMP Mix 400

Hemi Pharma TMP Mix 400 is the most premium injectable blend in the range, available exclusively through hemipharmauk.uk, the official UK website for Hemi Pharma pharmaceutical products. Each 10ml vial contains three long-ester compounds — Testosterone Enanthate, Methenolone Enanthate (Primobolan) and Drostanolone Enanthate (Masteron Enanthate) — combined at a total of 400mg per mL. Every vial carries a unique QR code that connects directly to the Hemi Pharma manufacturer database and confirms the batch, compound and concentration before the seal is broken.

The TMP Formulation — Three Compounds, One Injection

Hemi Pharma TMP Mix 400 combines three of the most respected injectable compounds in the Hemi Pharma range into a single vial. TMP stands for Testosterone, Masteron and Primobolan — three compounds that individually represent distinct pharmacological approaches to body composition and that, when combined in the enanthate ester at this ratio, create one of the most refined advanced cutting and recomposition blends available in the UK market.

Testosterone Enanthate forms the hormonal base at 200mg per mL. It provides the anabolic stimulus, maintains physiological androgen levels and supports all the functions that testosterone performs in an anabolic cycle — protein synthesis, nitrogen retention, IGF-1 stimulation and HPTA suppression management. At 200mg per mL of the total 400mg blend, testosterone enanthate provides the foundation upon which the other two compounds build.

Methenolone Enanthate (Primobolan) contributes 100mg per mL. Primobolan is a DHT-derived anabolic steroid that does not aromatise to oestrogen, does not convert to DHT further and is considered one of the mildest and most side-effect-friendly injectable compounds available. Its primary anabolic actions are nitrogen retention, preservation of lean muscle mass during calorie restriction and slow but highly retainable quality lean mass gains. Primobolan’s low androgenic activity relative to its anabolic effect makes it particularly valued in recomposition and advanced cutting cycles where the objective is maximum muscle preservation with minimum side effect load.

Drostanolone Enanthate (Masteron Enanthate) contributes 106.61mg per mL as confirmed by independent Janoshik testing. Masteron Enanthate is a DHT-derived anabolic steroid with significant anti-oestrogenic properties. It binds to the aromatase enzyme and reduces the conversion of testosterone to oestradiol, acting as a natural on-cycle oestrogen management tool alongside the Anastrozole that higher-dose cycles may still require. It produces pronounced muscle hardening, improved vascularity and enhanced muscle density that becomes increasingly visible as body fat percentage reduces. The enanthate ester means these effects build steadily over weeks rather than appearing and disappearing rapidly as with the propionate ester used in shorter cycles.

Janoshik Batch Test Results — All Three Compounds Above Declared Amounts

Hemi Pharma TMP Mix 400 Batch 1000 was submitted to Janoshik Analytical for independent testing in October 2024 under Task Number #51222. The results confirm all three compounds at or above declared amounts — a result that demonstrates manufacturing consistency of the highest standard across a three-compound blend, which is significantly more challenging to achieve than single-compound formulations.

Testosterone Enanthate returned 220.41mg per mL against a declared 200mg per mL. Methenolone Enanthate returned 105.98mg per mL against a declared 100mg per mL. Drostanolone Enanthate returned 106.61mg per mL against a declared 100mg per mL. The total measured active compound per mL is 433mg across all three compounds. The full certificate is published on the Hemi Pharma lab results page and is independently verifiable at janoshik.com using the key Y9ABGEMRVILH. This is the most important piece of evidence on this page. Every compound declared is present above the stated amount, independently confirmed by a laboratory that has no commercial relationship with Hemi Pharma.

Why This Specific Combination Works

The TMP Mix 400 formulation is built around a pharmacological logic that experienced users will recognise immediately. All three compounds use the enanthate ester, making the release profile, injection frequency and cycle management identical across the entire blend. There is no multi-ester complexity to manage as with Sustanon 250. All three compounds are administered in a single injection twice weekly and all three peak, sustain and clear on the same timeline.

Testosterone provides the anabolic base and hormonal foundation. Primobolan provides lean mass preservation and nitrogen retention without adding androgenic load or oestrogenic activity. Masteron Enanthate provides hardening, anti-oestrogenic activity and vascularity enhancement while also elevating the free testosterone ratio by suppressing SHBG. The three compounds complement each other across every mechanism without duplication or conflict. Testosterone aromatises to oestrogen and Masteron partially controls that aromatisation from within the blend itself, reducing but not eliminating the need for an external aromatase inhibitor depending on individual response and total dose.

This combination is specifically suited to advanced cutting and recomposition cycles where the objective is maintaining or building lean muscle mass while reducing body fat, with the hardening and vascularity effects of Masteron and the lean mass preservation of Primobolan amplifying the visual result of the testosterone base. It is not a bulking compound. There is no rapid mass-building ester in this formulation. It is an advanced aesthetic cycle compound that rewards patience and produces results that are sustainable beyond the cycle end.

Benefits of Hemi Pharma TMP Mix 400

Lean muscle preservation and accrual is the primary benefit of the TMP Mix 400 combination. Primobolan at 100mg per mL provides meaningful nitrogen retention and lean mass maintenance that protects hard-earned muscle during calorie deficits. Combined with the testosterone base maintaining anabolic signalling, muscle loss during aggressive cutting phases is significantly reduced compared to testosterone-only cycles at equivalent total androgen dose.

Muscle hardness and density improve progressively over the course of a TMP Mix 400 cycle as Masteron Enanthate builds to stable blood levels. Users typically report the hardening effect becoming pronounced from week four to six onward, intensifying throughout the cycle as body fat reduces and the muscular effects of drostanolone become increasingly visible beneath the skin.

Vascularity increases significantly from the combination of reduced subcutaneous water retention, Masteron’s direct effect on androgen receptor activity in adipose tissue and the elevated free testosterone from Masteron’s SHBG suppression. Users consistently report that vascularity on TMP Mix 400 exceeds what they achieve with Testosterone Enanthate alone at equivalent testosterone doses.

Natural on-cycle oestrogen management is partially provided by the Masteron Enanthate component. At the doses delivered by TMP Mix 400, the anti-oestrogenic activity of Masteron Enanthate at 106mg per mL may reduce or eliminate the need for an aromatase inhibitor in users who are sensitive to oestrogen management requirements. This is individual and dose-dependent and should always be confirmed with blood work rather than assumed.

Injection volume efficiency at 400mg total compound per mL means a substantial multi-compound cycle is delivered in a single low-volume injection. A 1ml twice-weekly injection schedule delivers 400mg of combined Testosterone Enanthate, Primobolan and Masteron per week — equivalent to running three separate compounds at meaningful individual doses without the administrative complexity of managing three different vials on three different schedules.

Side Effects of Hemi Pharma TMP Mix 400

The side effect profile of Hemi Pharma TMP Mix 400 is significantly milder than comparable-dose testosterone-only or testosterone plus trenbolone cycles. Neither Primobolan nor Masteron aromatises to oestrogen. The only aromatising compound in the blend is Testosterone Enanthate at 220mg per mL. At twice-weekly administration of 1ml per injection, the total weekly testosterone enanthate dose is 440mg — a moderate performance dose with predictable oestrogen management requirements that are partially offset by the Masteron component.

Androgenic side effects including acne, oily skin and accelerated hair loss in genetically predisposed individuals are possible, primarily driven by the testosterone component and the DHT-related activity of Masteron and Primobolan. Neither Masteron nor Primobolan aromatises, so oestrogen-related side effects are primarily driven by the testosterone fraction.

HPTA suppression is complete. All three compounds suppress natural testosterone production. Post cycle therapy using Hemi Pharma Tamox and Clomiphene Citrate is required at the end of every TMP Mix 400 cycle. Primobolan is often marketed as mild enough to not require PCT. This is incorrect. At the doses delivered by this blend, HPTA suppression is complete and PCT is mandatory.

Cholesterol impact is present with all three compounds. Masteron and Primobolan both reduce HDL cholesterol to a meaningful degree. Combined with testosterone, regular lipid panel monitoring throughout the cycle is recommended.

Cycle Guide — Hemi Pharma TMP Mix 400

Hemi Pharma TMP Mix 400 is an advanced compound suited to users with multiple cycle experience who understand the pharmacology of each component individually before combining them in a blend. It is not suitable for first-time or early-intermediate users.

A standard TMP Mix 400 cycle runs 1ml to 1.5ml twice weekly for twelve to sixteen weeks. At 1ml twice weekly the weekly dose is 440mg Testosterone Enanthate, 212mg Methenolone Enanthate and 213mg Drostanolone Enanthate based on the Janoshik-confirmed concentrations. At 1.5ml twice weekly the weekly dose is 660mg Testosterone Enanthate, 318mg Methenolone Enanthate and 320mg Drostanolone Enanthate. One 10ml vial provides five weeks of supply at 1ml twice weekly, or approximately three weeks at 1.5ml twice weekly. A full twelve-week cycle at 1ml twice weekly requires approximately two to three vials.

TMP Mix 400 can be used as a standalone cycle compound without additional injectables, which is one of its primary practical advantages. The testosterone provides the hormonal base, Primobolan provides the lean mass preservation and Masteron provides the hardening and partial oestrogen management. Some advanced users add Hemi Pharma Trenbolone Acetate for additional anabolic stimulus, though this significantly increases the compound load and should only be considered by experienced users who have run each compound individually.

PCT Timing After Hemi Pharma TMP Mix 400

All three compounds in TMP Mix 400 use the enanthate ester. PCT begins approximately two weeks after the last injection, consistent with the clearance window for all enanthate-ester compounds. A standard PCT protocol uses Hemi Pharma Tamox at 20mg per day and Hemi Pharma Clomiphene Citrate at 50mg per day for four to six weeks. Hemi Pharma HCG is best used in the final two weeks of the cycle before PCT begins. View the full Hemi Pharma PCT range.

Administration and Storage

What is Hemi Pharma TMP Mix 400 used for?

Hemi Pharma TMP Mix 400 is an advanced cutting and recomposition compound. The Testosterone Enanthate provides the anabolic base, Methenolone Enanthate preserves lean muscle mass during calorie restriction and Drostanolone Enanthate produces hardening, vascularity and partial on-cycle oestrogen management. It is not a bulking compound and is not suitable for first-time or early-intermediate users.

Does Hemi Pharma TMP Mix 400 require an aromatase inhibitor?

The Drostanolone Enanthate component provides partial anti-oestrogenic activity by competing with the aromatase enzyme, which may reduce oestrogen conversion from the Testosterone Enanthate component. Whether an aromatase inhibitor such as Hemi Pharma Anastrozole is required depends on individual response to the testosterone dose delivered by the blend. Blood work during the cycle is the only reliable way to confirm whether additional aromatase inhibition is needed.

When does PCT start after Hemi Pharma TMP Mix 400?

PCT begins approximately two weeks after the last injection of Hemi Pharma TMP Mix 400. All three compounds use the enanthate ester with consistent clearance timing. A standard PCT uses Hemi Pharma Tamox and Clomiphene Citrate for four to six weeks beginning two weeks after the last injection.

How often should I inject Hemi Pharma TMP Mix 400?

Twice weekly injection is recommended to maintain stable blood levels of all three enanthate-ester compounds. All three compounds in the blend share the enanthate ester, so a consistent twice-weekly schedule produces stable and predictable blood levels across the entire formulation without the ester mismatch management required by multi-ester blends.

Is Hemi Pharma TMP Mix 400 suitable for beginners?

No. Hemi Pharma TMP Mix 400 is an advanced compound for experienced users who understand the pharmacology of each component — Testosterone Enanthate, Primobolan and Masteron Enanthate — individually. Users should have completed multiple single and dual compound cycles before running a three-compound blend at this concentration.
