What is Supertest 375 (Sustanon)?

Supertest 375 is formulated with multiple testosterone esters, typically including:

• Testosterone Propionate – fast-acting ester for immediate results.
• Testosterone Phenylpropionate – medium ester for steady release.
• Testosterone Isocaproate – medium-long ester for hormone stability.
• Testosterone Decanoate – long ester for sustained performance.

This combination delivers immediate anabolic benefits while maintaining stable testosterone levels over time, making it a preferred choice for both bulking and cutting cycles.

• Oily skin, acne, or hair thinning in predisposed individuals
• Elevated blood pressure
• Suppression of natural testosterone (PCT required)

Friendly Suggestion

Since many UGL testosterone blends can be under-dosed or misrepresented, always choose trusted pharmaceutical brands like Xeno Labs USA. For peace of mind, check user reviews on Reddit, Trustpilot, and bodybuilding forums before purchasing.

And remember—after completing a testosterone cycle, always follow with a proper PCT to restore natural hormone levels, maintain fertility, and preserve your gains.
