  Boldenon 300 300mg/ml 10ml Vial by GenTec

  GenTec Boldenon 300 is a 300 mg/ml Boldenone Undecylenate injectable in a 10 ml multi-dose vial, purpose-built to support metabolic efficiency through improved glucose partitioning and sustained lean-tissue accrual during resistance-focused training blocks. Its moderate androgenic character drives preferential glycogen delivery into active muscle fibres while restraining the estrogenic fat accumulation associated with higher-aromatising androgens. Every production batch is subject to HPLC concentration verification and LAL endotoxin screening within a GMP-compliant facility prior to vial release.

  Drostan-E 250mg/ml 10ml Vial by GenTec

  Drostan-E by GenTec delivers drostanolone enanthate at 250 mg/ml — the highest concentration available in this class — as a long-acting injectable whose enanthate ester fundamentally extends active-release duration, enabling a reduced injection schedule while maintaining stable androgen levels across structured cycle protocols. Understanding ester selection is central to practical cycle design: the enanthate variant suits longer, less-frequent dosing frameworks, whereas shorter esters demand more injections to sustain comparable serum presence. HPLC-verified batch concentration and LAL endotoxin testing are applied per vial lot, with each certificate of analysis cross-referenced against stated label values before product release.

  NTD 400 400mg/ml 10ml Vial by GenTec

  GenTec NTD 400 is a 400mg/ml tri-ester injectable blend — Nandrolone Decanoate 100mg, Drostanolone Enanthate 100mg, Testosterone Enanthate 200mg — formulated specifically for cruise & blast mass-building protocols in a 10ml multi-dose vial. Each millilitre delivers 4,000mg of total active ingredient across the full vial, with long-acting esters sustaining stable plasma levels throughout extended blast phases without the need for daily injections. Quality assurance is enforced through HPLC concentration verification, LAL endotoxin testing, and GMP-compliant aseptic fill-and-finish; batch certificates are available per lot.

  Deca 300 300mg/ml 10ml Vial by GenTec

  GenTec Deca 300 is a Nandrolone Decanoate injectable solution formulated at 300 mg/ml in a 10 ml multi-dose vial, engineered for complete systemic bioavailability by bypassing first-pass hepatic metabolism — a pharmacokinetic advantage that no oral nandrolone format can replicate. Because the active compound enters the bloodstream directly through intramuscular absorption rather than the gastrointestinal tract, virtually 100 % of the administered dose reaches systemic circulation as active hormone. Each production batch undergoes HPLC potency verification and LAL endotoxin testing; sterility compliance is confirmed against GMP Annex 1 particulate standards before release.

  Testo-C 300 300mg/ml 10ml Vial by GenTec

  GenTec Testo-C 300 is a multi-dose injectable oil solution delivering Testosterone Cypionate at 300 mg per millilitre — engineered around the principle that intramuscular depot administration bypasses hepatic first-pass metabolism entirely, yielding near-complete systemic bioavailability compared to oral testosterone formulations that typically retain only 2–12% of the administered dose after liver processing. Each 10 ml vial supplies a full anabolic cycle dose at a high-concentration 300 mg/ml specification, maximising the amount of active testosterone reaching circulation per injection. Batch-release integrity is maintained through reversed-phase HPLC potency verification and LAL endotoxin screening; every vial cleared under GMP-compliant manufacturing conditions before distribution.

  Testo-E 300 300mg/ml 10ml Vial by GenTec

  GenTec Testo-E 300 is an oil-based injectable androgen delivering Testosterone Enanthate at 300 mg per millilitre in a 10 ml multi-dose vial — purpose-built for practitioners who follow contemporary evidence-guided dosing frameworks that favour moderate, precisely calibrated weekly administrations over legacy high-dose regimens. Modern dosing research consistently points toward 150–300 mg per week as the effective range where anabolic return is maximised while side-effect burden remains manageable and bloodwork stays within controllable parameters. Quality assurance at GenTec is enforced through HPLC-verified content uniformity and LAL endotoxin testing; every released lot satisfies GMP-aligned release criteria before distribution.

  Testo-Mix 400 400mg/ml 10ml Vial by GenTec

  GenTec Testo-Mix 400 is a high-concentration, oil-based injectable testosterone blend formulated at 400mg/ml across a 10ml multi-dose vial, built around a staggered four-ester pharmacokinetic architecture that delivers both rapid androgenic onset and sustained serum coverage within a single administration. The ester range extends from fast-hydrolysing propionate — producing measurable androgenic activity within the first 24 hours — through to slow-clearing decanoate, whose half-life of approximately 14–16 days anchors the terminal phase of each injection interval. Finished-product release is subject to HPLC concentration verification and LAL endotoxin screening; every batch must clear both analytical gates before distribution.

  Test-P 150 150mg/ml 10ml Vial by GenTec

  GenTec Test-P 150 is a high-concentration androgenic injectable supplying 150mg of Testosterone Propionate per millilitre — formulated to engage androgen receptors with the full binding affinity of endogenous testosterone, accelerated by the propionate ester's rapid hydrolysis kinetics. At 150mg/ml, each millilitre delivers 50% greater active compound than conventional 100mg/ml preparations, compressing effective dosing volumes without sacrificing androgenic precision. Batch integrity is confirmed through HPLC quantitative analysis and LAL endotoxin assay; GMP-qualified manufacturing partners supply the API under documented qualification audits.

  Tren-A 100 100mg/ml 10ml Vial by GenTec

  GenTec Tren-A 100 is a nandrolone-derived 19-nor anabolic steroid formulated at 100mg/ml in a 10ml multi-dose vial, distinguished by trenbolone's exceptionally high androgen receptor (AR) affinity — a binding characteristic that sets it structurally apart from testosterone-based compounds. Unlike simple testosterone esters, trenbolone acetate engages the AR with a dissociation constant that reflects its DHT-lineage architecture, enabling potent downstream anabolic signalling at comparatively lower circulating concentrations. Sterility and dosing precision across this vial are maintained through aseptic fill-and-finish operations independently verified by LAL endotoxin testing and HPLC quantitative assay on each production batch.

  Tren-E 200 200mg/ml 10ml Vial by GenTec

  GenTec Tren-E 200 is a sterile oil-based injectable solution delivering Trenbolone Enanthate at 200mg per millilitre across a 10ml multi-dose vial — engineered to circumvent hepatic first-pass metabolism that renders oral anabolic alternatives significantly less efficient. Because the active compound enters systemic circulation directly via intramuscular depot, virtually every milligram administered reaches androgenic target tissues without enzymatic degradation in the gut wall or liver. Quality control covers each production lot through HPLC-confirmed potency verification and LAL endotoxin screening conducted under GMP-compliant fill-and-finish conditions.

  Tri-Tren 250 250mg/ml 10ml Vial by GenTec

  GenTec Tri-Tren 250 is a 250 mg/ml multi-ester trenbolone injectable — combining Trenbolone Acetate, Enanthate, and Hexahydrobenzylcarbonate in a single 10 ml vial — engineered as the androgenic foundation for cycles in which human growth hormone supplies the primary anabolic stimulus. Three staggered ester fractions sustain circulating trenbolone across the full weekly dosing interval, maintaining androgenic signalling through every phase of HGH's slow, cumulative IGF-1 timeline. Each batch is released only after HPLC concentration verification and LAL endotoxin clearance are satisfied under GMP-compliant fill-and-finish conditions.
