Contraindications: Parabolan 100 must not be used by individuals with prostate or breast carcinoma, severe hepatic impairment, hypersensitivity to Trenbolone or oil-based injectable excipients, or active cardiovascular disease. Females should not use this compound due to its pronounced androgenic activity and high virilisation potential. Anyone under 21 or still in natural hormonal development should not administer anabolic steroids.
Side Effects: Trenbolone Hexahydrobenzylcarbonate is associated with androgenic effects (acne, scalp hair thinning, oily skin), cardiovascular strain (elevated haematocrit, adverse lipid shift — LDL increase, HDL suppression), significant HPTA suppression, potential insomnia, night sweats, and elevated aggression. 'Tren cough' — a transient, intense bronchospastic response — may occur immediately after injection in a subset of users.
Monitoring: Baseline and on-cycle bloodwork (full blood count, comprehensive metabolic panel, lipid panel, LH/FSH/total testosterone) is recommended before cycle initiation and at the 4–6 week mid-cycle mark. Blood pressure should be self-monitored weekly. Haematocrit elevation above 52% warrants cycle modification or cessation. Liver enzymes may be mildly elevated due to systemic anabolic load.
PCT: Post-cycle therapy with a SERM (Nolvadex or Clomid) should commence approximately two weeks after the final injection, once plasma Trenbolone levels have substantially cleared. Suppression from Trenbolone is pronounced; bloodwork-guided PCT duration of 4–6 weeks is appropriate, with confirmation of HPTA recovery via LH, FSH, and free testosterone assay before discontinuing SERM therapy.
