Tresto Ace 100 – Trestolone Acetate

Tresto Ace 100 is Syncom Labs' injectable form of trestolone acetate (MENT), a nineteen-nor anabolic steroid built on a short acetate ester. It binds strongly to the androgen receptor and drives fast gains in muscle and strength while also supporting fat loss, which is why it is used as a base compound in advanced recomposition cycles. It is a potent compound reserved for users who already have prior cycle experience.

Because acetate is a short ester, trestolone acetate needs to be injected frequently rather than once a week, typically every other day (EOD) to keep blood levels stable. As a guide rather than medical advice, a common protocol is around 25 mg EOD, giving roughly 75-100 mg per week, run for no more than 8 weeks and paired with a testosterone base throughout. The full usage guide on this product page has the complete protocol.

Yes. Trestolone suppresses natural testosterone production quickly and heavily, so an exogenous testosterone base of around 100-150 mg per week is run alongside it to maintain normal androgen function. An aromatase inhibitor such as anastrozole is also typically included, since trestolone can raise oestrogen-related side effects including gynaecomastia. PCT should begin about 3 days after the last injection, once both compounds have started clearing.

Users report severe suppression of natural testosterone, raised blood pressure, gynaecomastia, acne, hair loss, and worse cholesterol markers. Baseline bloodwork before starting, with follow-up checks around week 4 and after the cycle, should track testosterone, oestradiol, liver enzymes, lipids and blood pressure so the aromatase inhibitor dose can be adjusted if needed. This is not a compound for a first cycle.

Both are potent nineteen-nor compounds valued for recomposition, but they differ on oestrogen: trestolone aromatises and needs an AI on hand, while trenbolone does not aromatise at all. Both use a short acetate ester and are typically injected EOD to keep blood levels stable, but trestolone is generally considered even more suppressive to natural testosterone. Many experienced users treat trestolone as the more experimental, harder-hitting option of the two.
