Intex Pharma Testosterone Cypionate 200mg is an oil-based injectable testosterone ester supplied at 200mg per 1mL for intramuscular injection. Available from Intex Pharma UK, Testosterone Cypionate has a half-life of approximately 8 days, making it pharmacokinetically interchangeable with Testosterone Enanthate 300mg for both TRT and bodybuilding applications. A pharmacokinetic study published in Translational Andrology and Urology confirmed that intramuscular Testosterone Cypionate 200mg produces supraphysiological peak levels within 2 to 3 days, declining toward baseline by day 10, supporting once-weekly or twice-weekly injection frequency for stable serum concentrations. Every batch of Intex Pharma Testosterone Cypionate 200mg is independently tested by Janoshik Analytical with the Certificate of Analysis published in the product gallery.

Testosterone Cypionate 200mg vs Testosterone Enanthate 300mg: Which One to Choose
Testosterone Cypionate and Testosterone Enanthate are pharmacokinetically near-identical. Both are long-ester testosterone compounds with 8-day half-lives that produce the same anabolic and androgenic effects at equivalent testosterone doses. FDA prescribing information for Testosterone Cypionate confirms that both formulations exhibit identical serum testosterone profiles after intramuscular injection. The differences are practical, not pharmacological.
Testosterone Cypionate 200mg vs Testosterone Enanthate 300mg
| Parameter | Testosterone Cypionate 200mg (this product) | Testosterone Enanthate 300mg |
|---|---|---|
| Concentration | 200mg/mL | 300mg/mL |
| Injection volume for 500mg/week | 2.5mL per week | 1.67mL per week (less oil) |
| Injection volume for TRT (150mg/week) | 0.75mL per week (easier to measure precisely) | 0.5mL per week |
| Half-life | ~8 days | ~8 days (identical) |
| Best for | TRT and lower-dose protocols where precise measurement of smaller volumes matters. Users who prefer the standard US-prescribed concentration | Higher-dose blast cycles where less injection volume is preferred. Users who want fewer mL per injection at bodybuilding doses |
| Price | £37.00 | £41.00 |
The practical takeaway: Testosterone Cypionate 200mg is the better choice for TRT and cruise doses (100 to 200mg/week) because the lower concentration allows more precise volume measurement with a standard syringe. Testosterone Enanthate 300mg is the better choice for blast doses (300 to 600mg/week) because the higher concentration means less oil injected per session. Both produce identical results at the same testosterone dose. For the complete guide to running testosterone as a beginner, see the Intex Pharma beginner cycle guide.

Testosterone Cypionate 200mg: Applications and Dosing
| Application | Weekly Dose | Volume per Week | Notes |
|---|---|---|---|
| TRT / cruise | 100 to 200mg | 0.5 to 1.0mL | Maintains physiological testosterone. Split into 2 injections per week (0.25 to 0.5mL each) for more stable serum levels and reduced oestrogen conversion |
| Cutting base | 150 to 200mg | 0.75 to 1.0mL | Provides anti-catabolic support during caloric deficit. Pairs with Retatrutide 2mg for appetite control and Clenbuterol 40mcg for thermogenesis |
| Moderate blast | 300 to 500mg | 1.5 to 2.5mL | Standard bodybuilding dose. Monitor oestradiol and adjust AI as needed. Run HCG 5000IU at 250 to 500IU twice weekly for testicular maintenance |
| Test base with 19-nors | 150 to 300mg | 0.75 to 1.5mL | Base alongside Nandrolone Decanoate 300mg or Trenbolone. Include Cabergoline 0.25mg for prolactin management per the cabergoline dosing for Deca and Trenbolone guide |
Run pre-cycle bloodwork before starting any testosterone protocol. Monitor testosterone, oestradiol (sensitive LC-MS/MS), haematocrit and lipids mid-cycle. For bloodwork interpretation, see the testosterone bloodwork interpretation guide. Plan PCT with Nolvadex 20mg per the PCT protocol with HCG and Clomid.

Testosterone Cypionate 200mg: Frequently Asked Questions
What is the difference between Testosterone Cypionate and Testosterone Enanthate?
Pharmacologically, almost nothing. Both are long-ester testosterone compounds with approximately 8-day half-lives that produce identical anabolic and androgenic effects at equal testosterone doses. The ester weight differs slightly (Cypionate delivers marginally more testosterone per milligram due to a lighter ester), but the difference is clinically insignificant. The choice is practical: Cypionate at 200mg/mL suits TRT dosing precision, while Enanthate at 300mg/mL suits higher blast doses with less injection volume.
How often should I inject Testosterone Cypionate 200mg?
Once or twice weekly. Twice-weekly injections (splitting the total weekly dose into two equal shots) produce more stable serum testosterone levels, reduce the peak-to-trough fluctuation that drives oestrogen conversion and side effects, and make the protocol feel smoother with fewer mood and energy swings compared to a single weekly injection.
Is Testosterone Cypionate 200mg good for TRT?
Testosterone Cypionate 200mg is the standard TRT formulation prescribed worldwide. The 200mg/mL concentration allows precise dosing at typical TRT ranges (100 to 200mg weekly) using standard syringes. At 150mg weekly, you inject 0.75mL: easy to measure accurately and split into two 0.375mL doses for twice-weekly administration.
Do I need PCT after Testosterone Cypionate?
Yes, if you are cycling off rather than staying on TRT. Exogenous testosterone suppresses the HPTA (hypothalamic-pituitary-testicular axis). When you stop injecting, natural production does not restart automatically. PCT with Nolvadex 20mg and optionally HCG is required. Wait approximately 2 weeks after your last Cypionate injection before starting PCT to allow the ester to clear.
Can I switch between Testosterone Cypionate and Enanthate mid-cycle?
Yes. The pharmacokinetics are near-identical. Maintain the same weekly testosterone dose in milligrams and adjust the injection volume for the different concentration. Switching from Cypionate 200mg/mL to Enanthate 300mg/mL at 500mg weekly means changing from 2.5mL to 1.67mL per week. No washout period is needed.
Is Intex Pharma Testosterone Cypionate 200mg third-party tested?
Yes. Every batch is independently tested by Janoshik Analytical for compound identity, concentration and sterility. Accurately dosed testosterone is essential for stable serum levels, consistent oestrogen management and predictable cycle outcomes. Verify the Certificate of Analysis at the Intex Pharma COA guide.
