Testosterone Replacement Therapy in Canada | TRT Compounds, Protocols & Ancillaries
Canada Steroid Depot's TRT category stocks the complete range of testosterone formulations and ancillary compounds used in testosterone replacement therapy research. From long acting injectable testosterone esters favored for stable serum concentrations, to short acting esters for more frequent dosing protocols, to transdermal gels for needle free administration. TRT research encompasses not only testosterone formulation selection but also the management of estrogen, hematocrit, fertility preservation, and HPG axis considerations that arise during long term testosterone administration.
Injectable testosterone esters for TRT
Injectable testosterone esters are the most widely researched TRT administration format due to their predictable pharmacokinetics, cost effectiveness, and precise dosing. Testosterone Enanthate (half-life 7–10 days) and Testosterone Cypionate (half-life 8–12 days) are the two most commonly used long acting esters in TRT protocols. Typically administered once or twice weekly to maintain stable serum testosterone levels within the physiological reference range. Testosterone Propionate (half-life 2–3 days) is used in more frequent micro dosing protocols that more closely mimic the natural testosterone secretion pattern. Sustanon 250; a blend of four testosterone esters provides both rapid onset and sustained release but produces less stable serum concentrations compared to single ester protocols.
Testosterone gels and topical formulations
Transdermal testosterone gels offer a needle free alternative to injectable TRT, delivering testosterone through the skin for absorption into systemic circulation. Topical formulations produce more stable daily testosterone levels compared to weekly injections but require daily application and carry a transfer risk to partners or children through skin contact. CSD stocks testosterone gel formulations for researchers investigating transdermal testosterone delivery as an alternative or adjunct to injectable protocols.
Estrogen management on TRT
Testosterone aromatizes to estradiol via the aromatase enzyme and on TRT, elevated estradiol is one of the most commonly managed variables in long term testosterone research. Optimal estradiol range on TRT is an area of active research debate, but most protocols aim to keep estradiol within a range that preserves bone density, cardiovascular health, libido, and mood while avoiding estrogen excess symptoms. Aromatase inhibitors such as Anastrozole and Exemestane are the most commonly researched estrogen management compounds on TRT. CSD stocks a full range of AIs in the Estrogen & Prolactin category.
Fertility preservation on TRT
Exogenous testosterone suppresses the HPG axis, reducing LH and FSH secretion and consequently suppressing spermatogenesis and intratesticular testosterone production. For researchers investigating fertility preservation concurrent with TRT, the most commonly studied approaches include HCG monotherapy or HCG co-administration alongside testosterone to maintain intratesticular testosterone and testicular volume, FSH supplementation for spermatogenesis support, and Gonadorelin pulsatile therapy as an HPG axis preserving alternative to conventional TRT. CSD stocks HCG, FSH, HMG, and Gonadorelin in the Fertility category.

Testosterone Enanthate and Testosterone Cypionate are pharmacologically very similar; both are long acting testosterone esters with half-lives of 7–12 days, both are typically administered once or twice weekly, and both produce comparable serum testosterone levels at equivalent doses. The primary difference is the ester chain length. Cypionate has a slightly longer half-life and is more commonly prescribed in North America, while Enanthate is more common in Europe. In research practice the two are largely interchangeable.
Physiological TRT doses in research contexts typically range from 100–200mg per week of Testosterone Enanthate or Cypionate, administered as a single weekly injection or split into two equal doses. The goal is to restore serum total testosterone to the mid to upper physiological reference range (typically 500–900 ng/dL) while minimizing supraphysiological peaks and troughs.
HCG co-administration alongside TRT is commonly researched as a strategy to maintain testicular function, intratesticular testosterone production, and fertility during long-term testosterone replacement. Typical HCG protocols alongside TRT use 250–500IU administered twice weekly. HCG maintains testicular size and spermatogenesis in research subjects who wish to preserve fertility during testosterone administration.
