Product Overview
Best Anabolic Steroids lists GP Cock Bombs 70 from Geneza Pharmaceuticals: 50 oral tablets, described by the pack name as carrying 70 mg in total per tablet. The product is not a hormone and not an anabolic compound. It is a combination of two pharmaceuticals from the same class, sildenafil citrate and tadalafil, the actives behind the two best known erectile dysfunction medicines.
The class works on a single pathway. Sexual stimulation releases nitric oxide, which drives the production of cyclic GMP in the arterial smooth muscle of the penis; that messenger relaxes the vessels and lets blood in. An enzyme called phosphodiesterase type 5 dismantles cyclic GMP, and a PDE5 inhibitor slows that dismantling down. The important consequence is in the mechanism itself: no arousal means no signal to preserve, so a tablet on its own achieves nothing.
Two molecules from different sides of the class were chosen for the combination. Sildenafil enters and leaves quickly, so it suits a single planned occasion, while tadalafil stays in the body for the better part of a day, which is why it is often called the weekend product. Putting one tablet together from a short-acting and a long-acting agent is a formulation decision, not a therapeutic one: the pairing has not been approved by any regulator, and the individual substances are normally sold as separate medicines with their own dosing limits.
Dosage Protocol
This tablet has no approved dose, and no published schedule covers two agents from the same class inside one day. What the sources do contain are reference regimens for each component on its own, and those figures do not transfer to a tablet that already holds both.
| Sildenafil reference | One hour ahead of activity; 25-50 mg is the opening range and 100 mg is the top of the label in one day |
| Tadalafil reference | 10 mg for a single occasion, or 2.5-5 mg every morning as a steady background; never more than 20 mg in a day |
| Combination | Nothing is established for the two actives together; the extra fall in blood pressure is not characterised |
| Onset | Sildenafil is felt in 20-30 minutes and covers four to six hours; tadalafil starts near 30 minutes and can reach 36 hours |
| Female | Not applicable here: the label covers men with erectile dysfunction |
| Administration | By mouth, roughly 30-60 minutes ahead; a heavy greasy meal delays uptake, while grapefruit and CYP3A4 inhibitors push the level up |
Because the tablet is fixed, the components cannot be balanced against each other. Onset, duration and side effect profile differ between them, and the profile of one molecule is not the profile of the other: the visual symptoms belong to sildenafil and the muscle aches to tadalafil. Anyone wanting the long window alone is better served by a single-agent product than by a blend, which is also true of anyone who wants only the short one.
The one rule that is not a matter of preference concerns nitrates. Nitrate medicines, nitric oxide donors and riociguat must be avoided altogether with this class, because the combined drop in blood pressure can be sudden and severe. That interaction does not depend on the dose.
Suggested Protocols
This is a symptomatic product, used when it is needed rather than on a schedule. In a bodybuilding context it appears mainly during cycles that interfere with erection quality.
What to Expect
- Sildenafil acts inside half an hour. The window then closes within four to six hours, and stimulation is required throughout for any effect at all.
- Tadalafil stretches the day. Its terminal half-life is around 17.5 hours and the effect is described out to 36 hours, which is why it is used differently.
- Daily tadalafil builds slowly. A steady level is reached near the fifth day at 2.5-5 mg a day, and the pharmacology is linear between 2.5 and 20 mg.
- The two halves feel different. Visual symptoms track sildenafil and back or muscle pain tracks tadalafil.
- Food and timing matter. A heavy meal delays the effect, and grapefruit or drugs that block CYP3A4 push concentrations up.
- No sport benefit is established. Despite the vasodilation, the sources do not support an ergogenic effect in training.
Side Effects and Management
The class is well characterised on its own, and the practical risk here comes from the combination and from one interaction that must be ruled out before anything is swallowed.
Post-Cycle Therapy
Recovery therapy is not part of this product, and that is a factual statement rather than a simplification. PDE5 inhibitors act on the enzyme that breaks down cyclic GMP in vascular tissue; they do not interact with the gonadal axis, they do not suppress luteinising hormone, and they trigger no shutdown that would need to be reversed. Where a cycle has caused the problem this tablet is bought for, the therapy belongs to that cycle, not to the tablet.
